"Dinosaurs' Impact on Human Aging: Unveiling the Longevity Connection"

A new hypothesis suggests that the dominance of dinosaurs millions of years ago may have led to a "longevity bottleneck" in mammals, including humans. During the age of dinosaurs, smaller mammals had to reproduce quickly to survive, potentially discarding genes for longer lifespans. The research notes that ancient mammalian ancestors lost certain enzymes that repair damage caused by ultraviolet light, possibly due to becoming more nocturnal. Other signs, such as the inability to continuously grow teeth like reptiles, also point to genetic selection dating back to the time of dinosaurs. Understanding the factors behind aging could help in fighting age-related diseases.
