Fossils in the ‘Cradle of Humankind’ may be more than a million years older than previously thought - Purdue University News

As I have pointed out many times here and on the social media, as well as in my popular book, What Makes You So Special: From The Big Bang to You., far from the often repeated creationist lie that there are no transitional fossils, there are actually so many of them that they serve only to cloud, not clarify the picture. Just when you think there is a nice direct line from a species of Australopithecus up to say, Homo erectus and thence to us, up pops another Australopithecus that might be a side branch or it might be an early ancestor of Homo sapiens. In the end we are left with a confusing collection of ancient African fossils that might or might not be our direct ancestors or might or might not be the ancestors of am extinct side branch, with no real way to determine which.

The picture is confused further when the fossils from which DNA has been extracted show that early hominins had a tendency to spread over a very wide range, evolve for a while in isolation, but not enough to be incapable of interbreeding with a cousin species, then come back together again and exchange DNA by interbreeding, so we may in fact never have had a single original distinct ancestral species but we are the descendants of two or more that hybridized.

Now the picture has been clarified a little by a scientists from Purdue University, West Lafayette, Indiana, USA, the University of the Witwatersrand, Johannesburg, South Africa, and the University Toulouse Jean Jaurès, Toulouse, France, who have used a new dating method developed by Dr Darryl Granger of Purdue University to reassess the date of several hominin fossils found in the Sterkfontein Caves, South Africa and pushed their dates back more than a million years. This makes them older that 'Lucy' (Au. afarensis) who is believed to be close to our direct Australopithecine ancestor, if not actually our ancestor. It is hoped, that more accurate dating will leader to a more accurate placing of these fossils over time, so making lineages easier to identify.

Climate Emergency News - Temperature Change Will Impact on Bumble Bees

Climate change negatively impacting bumblebees: Study - SFU News - Simon Fraser University

A stark reminder of the effects of climate change and the danger this represents to life on Earth, was published recently in the form of a study into the effects of global warming on the population of bumblebees in North America. The study was conducted by scientists from Simon Fraser University, Burnaby, B.C., Canada, led by Hanna Jackson, in collaboration with scientists from the U.S.-based Pollinator Partnership, the Xerces Society for Invertebrate Conservation, and the Department of Biological Sciences at the University of Southern California.

Their findings were published, open access, in the Royal Society's Biology Letter

bumblebees are essential pollinators on which many plants depend for their reproduction and without which many plants would not produce the next generation. They are also essential for pollinating a number of human food crops from oilseed rape to fruit, so a significant loss of bumblebees would be economically catastrophic.

The Simon Fraser University press release explains the team's methodology and main findings:

Atheism - Winning in Australia

Census 2021 results: Christianity plummets as ‘non-religious’ surges

Figures released today show that, like elsewhere in the civilised, advanced world, Australians are abandoning religion in droves. The percentage of Australians who described themselves as 'Christian' in the 2021 census fell below 50% to 44% for the first time in Australia's history.

This figure has fallen from 52% in just 5 years. In 2011 it stood at 61%. When a census was first conducted in Australia in 1911, 96% of Australians identified themselves as Christian.

These figures are revealed in the first tranche of data to be released from last years census. The percentage who ticked the 'no religion' box stood at 39%, up from 30% just 5 years ago, and almost double what it was in 2011. Those who identified as Catholic fell 3 percentage points to 20% and Anglican fell 3 percentage points to 10%. Falls in other minor Christian denominations brought the total figure for Christians as a whole down to 44% from the 52% recorded just 5 years ago.

The percentage of Australians self-identifying as 'non-religious' is highly significant because it shows the extent to which 'non-religious' has become acceptable in Australia. In the mid-1960s only 1% of Australians so self-identified. What we are seeing in Australia is what we saw in the UK, where the social stigma of having no religion, so being perceived wrongly as immoral and untrustworthy, has gone, to be replaced by a more realistic perception of intelligence, compassion and integrity, so more and more people are coming out of the closet.

Covidiot News - Another Reason Why Pregnant Women Should Be Vaccinated Against COVID-19

Covid-19 vaccination during pregnancy reduced the risk of hospitalisation with COVID-19 for babies under 6 month-old by 80% for the Delta variant and by 40% for the Omicron variant.

COVID-19 Vaccination in Pregnancy Helps Protect Infants from Needing Hospital Care for COVID-19 | Lurie Children's

Contrary to the antivaxx propaganda coming from the extreme right in the USA, a new study, sponsored by the US Center for Disease Control and Prevention (CDC), has shown that COVID-19 vaccination during pregnancy reduced the risk of babies under 6 month old needing hospitalization due to COVID-19 infection, by 80% during the Delta wave and 40% during the Omicron wave.

The study, led by Dr. Bria M. Coates, MD, was conducted by investigators from the Ann & Robert H. Lurie Children’s Hospital, Chicago and the Northwestern University Feinberg School of Medicine, Chicago. It included infants younger than 6 months of age who were admitted to 30 paediatric hospitals in 22 states from July 1, 2021, to March 8, 2022. Dr Coates and his colleagues found that most infants (90 percent) who needed intensive care due to COVID-19 infection were born to mothers who were not vaccinated during pregnancy.

The results were published a few days ago in the New England Journal of Medicine.

The Ann & Robert H. Lurie Children’s Hospital press release explains the importance of these findings:

Fake News - Why People Believe False Stories and Disinformation

Why We Fall for Disinformation | Psychology Today

In a report published recently by the US Center for Naval Analysis (CNA) a team of psychologists analysed the reasons why so many people are falling for disinformation. The problem us due to the way we have evolved to deal with information and the fact that this has ill-prepared us to deal with the vast amount of information now being directed at us by modern technology.

In fact, some of the time-tested tools make us dangerously vulnerable to disinformation, especially disinformation designed to mislead and garner support for extremist groups for whom the truth would be toxic. We see this today in the form of disinformation about, for example, COVID-19, the measures to reduce its spread and the vaccines designed to protect us from it. We also see it in relation to politics, political movements and parties, international affairs, religious fundamentalism and anti-science propaganda, such as climate change and evolution, and especially conspiracy theories such as those promulgated by QAnon and former President, Donald Trump's supporters, intended to radicalise, undermine confidence in institutions, and garner support for extreme solutions to non-existent problems.

In other words, disinformation campaigns are designed to benefit those whom the report calls 'malign actors', for whom the truth would be dangerous and who know they need their target marks to believe falsehoods and mistrust the evidence.

In the abstract to their report, the psychologists, Heather Wolters, Kasey Stricklin, Neil Carey, and Megan K. McBride, say:

Confidence in U.S. Supreme Court Sinks to Historic Low

Confidence in U.S. Supreme Court Sinks to Historic Low | Gallop

According to the latest Gollop Poll, the damage the disastrous president, Donald Trump, did to American democracy continues to fester.

This time it is a dramatic collapse in the level of trust in the Supreme Court that Americans have, since Trump appointed overtly partisan Republican placemen to SCOTUS while in office. A flourishing democracy needs an independent judiciary, not an overtly partisan one, but SCOTUS is now expected to deliver verdicts demanded by the right-wing political fringe and religious fundamentalists, while ignoring the wishes and opinions of mainstream Americans. Consequently, the percentage of Americans who say they have a great deal or quite a lot of trust in SCOTUS has fallen to a new low of just 25%, an 11 percentage point fall in just the last year.

Evolution News - How Humans Evolved to Get Along With Neighbours

Shared grooming among bonobos is indicative of their group dynamics, which includes tolerance and cooperation.

Bonobos’ tolerant, peaceful group relationships paved way for human peacemaking – Harvard Gazette

Despite our long history of often religiously-inspired wars, and divisions into mutually-hostile camps, humans are actually quite good at getting along with neighbouring social groups, and peace-making is generally considered a noble activity, while war-mongering is generally despised.

In this respect we much more closely resemble the peaceable bonobos with whom we share 99% of our genes, than the equally closely related chimpanzees.

Not surprisingly, because it is an innate human trait, early Christians tried to claim credit for the idea that peace-making is a skill to be admired, with "Blessed are the peace-makers". The pity is, because they only saw things in selfish terms, they made it look like something only worth doing for a personal reward and not for the greater social good, because it leads to greater human happiness. Ironically, with peace-making featuring in their Beatitudes (Matthew 5:9), it may well be the result of evolution and an indication of our common ancestry with the bonobo.

But how did we get this way?

Covidiot News - More Figures Show How Antivaxxer Covidiots Were Culling Their Own Supporters with COVID-19

High vaccination rates blunted Delta variant surge in some US states | For the press | eLife

Figures published yesterday in eLife, show that, during the Delta variant wave of COVID-19 in the summer of 2021, areas with a high level of vaccine take-up in the USA had a lower peak of hospitalisations and deaths, and a shorter duration of the wave, compared to areas where the take-up was low.

The summer of 2021 was of course when pro-Trump QAnon, antivaxxers and evangelical Christians were loudest in campaigning to mislead people about the severity of the pandemic and the effectiveness/harmful effects of the COVID-19 vaccine, as a direct consequence of then president Trump's incompetent response to the crisis where he was out of his depth, so sought to minimise it to justify his inaction and indecision, so setting the scene for his supporters in the far right Trumpanzee cults. Consequently, those parts of America where a large number of people, mostly Trumpanzee Republicans, were refusing to get vaccinated or take sensible precautions against catching the virus and passing it on to others.

Now figures are showing the harm that did to those who fell for the lies emanating from the White House, and so made themselves vulnerable to the potentially life-threatening condition.

Why vaccination against malaria quickly loses its protective effect

Scientists in Germany have worked out why immunity to malaria is not very effective and has a very short duration.

Malaria is one of the world's biggest killers. It is caused by a number of different, closely related Plasmodium parasites, normally transmitted by Anopheles mosquitos. The commonest parasite is Plasmodium falciparum and the most efficient vector is Anopheles gambiae. According to the US Center for Disease Control (CDC):

Malaria is one of the most severe public health problems worldwide. It is a leading cause of death and disease in many developing countries, where young children and pregnant women are the groups most affected. According to the 2021 World Malaria Report:

• Nearly half the world’s population lives in areas at risk of malaria transmission in 87 countries and territories.
• In 2020, malaria caused an estimated 241 million clinical episodes, and 627,000 deaths. An estimated 95% of deaths in 2020 were in the WHO African Region.

Now Scientists from the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) who studied the human immune response after immunization with the malaria pathogen Plasmodium falciparum have discovered that the immune response has a very short duration. They concluded:

Evolution News - How Plants Colonised the Land.

The diversity of flora and fauna as we know them today and the substrate on which thrive are thanks to a single species of algae that first went ashore more than 500 million years ago. This and all other drawings in the publication are by the paper’s first author, Dr. Mona Schreiber.

Universität Düsseldorf: The Greening Ashore.

A team led by evolutionary biologist Prof. Dr. Sven Gould of Heinrich Heine University Düsseldorf (HHU) has been studying the current state of research on the plant colonisation of land that occurred some 500 million years ago. The findings from this illustrated overview study published by Dr. Mona Schreiber as lead author have now appeared, open access, in the latest issue of the journal Trends in Plant Science.

It was to take several hundred million years for Earth to cool sufficiently for oceans and landmasses to form then the conditions on land were far from conducive to the life that was evolving in the oceans to begin to colonise that land. Until about 500 million years ago, seismic activity meant the atmosphere was toxic and a weaker magnetic field meant UV light was more intensive. Then things began to change, and all terrestrial plant life has developed from the first plant species, a streptophyte alga, that began to move out of the oceans onto land. This was followed by simple animal life which in turn created the opportunities for tetraploid vertebrates to exploit by coming onto the land, developing air-breathing and a tetrapodal lifestyle.

Evolution News - Why Cave-Dwelling Species Appear to be Degenerate

White, fat and blind — Economy and evolution in caves: Current Biology

One of the aspects of evolution that creationists find difficult to cope with is the fact that, in the right environmental conditions, evolution can result in a loss of complexity, whereas, to make it easier to attack, creationist dogma defines evolution as an increase in complexity (which they then claim is impossible due to misrepresentation of the Second Law of Thermodynamics and Shanning Information Theory). For example, many parasitic organisms, particularly intestinal worms, have lost their digestive systems and absorb nutrients directly from the pre-digested contents of their host’s gut.

Other examples can be found in species adapted for living in caves which often lose their eyes and/or pigmentation. Once it was thought that these were examples of regression as these were the remnants of competition with their fitter, surface-dwelling relatives which had taken shelter in the safety of caves. Darwin found them difficult to explain because there seemed to be no obvious way in which a loss of function could be advantageous. At one point, Darwin seemed to accept a Lamarckian explanation for the loss of eyes in that their loss was a direct consequence of their lack of use.

Malevolent Designer News - Where Creationism's Favourite Sadist Released the Black Death on Humanity

The Black Death was one of Creationism's divine malevolence's earlier attempt to kill millions of people, and it was spectacularly successful, reducing the population of Eurasia by up to 60% between 1346 and 1353, and wiping out some villages completely - that is, of course, if you buy into the intelligent [sic] design hoax that says complex organism must have been designed because evolution doesn't happen, and even if it does, it can't account for complexity [sic].

The Black Death, which theologians at the time were in no doubt was some form of divine retribution - for whatever they said it was for. The shock of it to devout European Christian culture caused all sorts of obscure sects to arise, like the flagellants, who walked about beating themselves with whips. The obvious fact that praying to dead ancestors called saints and begging them to intercede with God and put a stop to the plague, wasn't working, coupled with a widespread belief that it was the routine debauchery and corruption within the Catholic Church that had resulted in divine retribution, eventually led to a fundamental reassessment of how people saw their relationship with God, culminating in the Protestant Reformation.

The pandemic was caused by the organism Yersinia pestis and a large team of researchers, including scientists from the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, the University of Tübingen, Germany, and the University of Stirling, Scotland, UK have worked out exactly where it started, something that has long been a mystery. They did this by studying the genome of ancient samples of Y. pestis

Superstition News - Abandonment of Religion Accelerating in USA

Belief in God in U.S. Dips to 81%, a New Low

A new Gallop survey shows an accelerating fall in belief in God amongst American adults, and this trend hold true across all demographic grouping, whether age, race, geography of political leaning.

Belief in God is now at it's lowest (81%) since Gallop started polling on the issue. During the years 1944 to 2011 it had averaged just over 93% (range 92%-98%) but since then it has fallen by 12 percentage points, with half that fall occurring over the last year. To put that another way, the number of people admitting to not believing doubledlast year and now stands at 19% of American adults. An astonishingly high level of belief for an advanced economy, compared to that in most of Europe, but a very encouraging recent trend.
