Dinosaurs may be to blame for human aging

The dominance of dinosaurs may have led to mammals losing their longevity genes, suggest researchers at the University of Birmingham. This evolutionary shift prioritized rapid reproduction over longevity.
A microbiologist at the University of Birmingham University of Birmingham named João Pedro de Magalhães has proposed that the rule of dinosaurs forced mammals to speed up their reproductive cycles by eliminating key longevity genes. This was reported by UNN with references to BioEssays and Popular Mechanics.

The evolutionary pressure that dinosaurs exerted as predators for 100 million years may have caused "the genes that regulated the mechanisms of repair and regeneration in mammals. This hypothesis was put forward by Professor of Molecular Biogerontology University of Birmingham, João Pedro de Magalhães, in a study published in the journal BioEssays.
According to the microbiologist, the era of dinosaur dominance completely changed the evolutionary path of almost every mammal on Earth, refocusing evolutionary efforts on rapid reproduction instead of long life.
My hypothesis is that such prolonged evolutionary pressure on early mammals to reproduce rapidly led to the loss or inactivation of genes and pathways associated with longevity

The theory is confirmed by the lack of mammalian regenerative abilities similar to those of reptiles and amphibians. those of reptiles and amphibians.
Although it is only a hypothesis at this point, there are many interesting aspects to consider, including the prospect that cancer is more common in mammals than in other species due to the rapid aging process
