Creationists assert that humans are the special creation of their designer god, placing humanity at the pinnacle of 'creation'. Even those theists who accept the Theory of Evolution but believe it was guided by God with humans as the intended ultimate outcome, regard humanity as their deity's supreme achievement.
If this claim were accurate, it would be reasonable to expect humans to possess the optimal anatomical and physiological characteristics across all biological systems. In reality, numerous species exhibit superior traits and abilities compared to humans—traits which, had they been bestowed upon humans, would have significantly improved our wellbeing and survival capabilities.
For instance, birds have a respiratory system far superior to mammals, including humans, enabling efficient oxygen exchange during flight. Raptors possess remarkable eyesight, allowing them precise vision at speeds that would render nearby objects a mere blur to human vision. Elephants, sharks, and naked mole rats exhibit extraordinary resistance to cancer. Furthermore, many mammals experience lower perinatal mortality rates than humans even with modern medical intervention.
As highlighted in a recent study published in PLOS Biology, bats tolerate viral infections that are often fatal to humans, so they can harbour evolving viruses that, when they find their way into humans, can result in serious pandemics such as the recent COVID-19 pandemic.
If we entertain the creationist argument, their purported intelligent designer had already perfected these advantageous traits in other species. Yet, paradoxically, humans were deprived of these beneficial adaptations. This scenario suggests a designer whose decisions could only be interpreted as either incompetent or malevolent. It is the equivalent of a car manufacturer having designed a super-efficient, low-emission and cheap engine in one of its models, continuing to fit an old, expensive, wasteful and polluting engine to its top of the range model.
However, the evolutionary explanation — that different species evolved distinct traits adapted specifically to their environmental pressures — fully clarifies why humans possess adequate but not necessarily optimal traits. Unfortunately for creationists, adherence to their dogma forces them to dismiss this rational explanation, instead endorsing a narrative that inadvertently portrays their intelligent designer as either incompetent, malevolent, or potentially both.
That bats have superior immune system to humans has long been known, but why that is in terms of their cell physiology is still something of a mystery. Now, however, a team of researchers led by Washington State University molecular virologist Michael Letko has developed two lines of bat cell cultures which can be used to study how their immune system responds to different viruses, for example, the ebola virus, with a view to utilising that information to treat infections in humans.
Their findings are the subject of a research paper in PLOS Biology and are explained in a Washington State University (WSU) news item:
