“Why did most mammals stop laying egg? The credit or blame probably goes to virus -a distance relative of HIV that has infected mammals so thoroughly that there are now thousands of old broken copies of the virus littering your DNA. Part of one virus, called syncytin, still works. Syncytin effectively transforms the pregnant mother into a walking egg by passing nutrition and oxygen across the womb.” 🤯

“Controversial studies suggest that people prefer mates who smell different to themselves. This difference in odour is caused by the MHC, which controls the expression of cell surface receptors & plays a key role in immunity. Intriguingly, it has been suggested that women taking the contraceptive pill prefer males with MHC similar to their own, while those not taking it prefer different odours.”

“No scientific theory is worth anything unless it enables us to predict something which is actually going on. Until that is done, theories are a mere game of words.”

“Darwin noted that extinction happens gradually. A species dwindles, until competition or some unlucky event finally nudges it over the edge. […] Now that humans can colonize every environment from seabed to space, we have ourselves become a major cause of extinction; come the next big extinction, will we die like dinosaurs or brazen it out like brachiopods?”
