Did you know that people can live for 200 years? However, dinosaurs did not allow this to happen.

According to a recent study, humans could have lived for up to 200 years longer if dinosaurs had not existed.

Microbiologist Joao Pedro de Magalhaes of the University of Birmingham in the United Kingdom has highlighted a clear contrast between how swiftly mammals, such as humans, age and how reptiles and amphibians age.

The disparity is most likely due to the dinosaurs' dominance on this planet millions of years ago, particularly during a critical phase in mammalian history.

The microbiologist describes his "longevity bottleneck" hypothesis in a newly published paper, explaining that when dinosaurs ruled the Earth,

 it became important for the much smaller mammals to reproduce quickly for survival, which likely led to the discarding of genes for longer lifespans as evolution progressed.

"Some of the earliest mammals were forced to live towards the bottom of the food chain, 

and have likely spent 100 million years during the age of the dinosaurs evolving to survive through rapid reproduction," said de Magalhaes, in a research published by Science

"That long period of evolutionary pressure has, I propose, an impact on the way that we humans age," he went on to say.

According to the findings, the ancient ancestors in the eutherian mammal lineage are likely to have lost particular enzymes during the time when dinosaurs were prevalent, including enzymes that aid in the repair of UV-light damage to our skin.
