Eli5. What decides an animals longevity as for as mortality? A horse, way stronger and healthier than most humans, live only to around 20 to 30 years, yet the steady rate when humans expire is around 70 to 80 years. How does this work?
In: Biology
The faster a speices cells divide, the longevity of their organ tissue, the efficiency of their kidneys and liver, and their diet and lifestyle all factor into age.
Human tissue is pretty long lasting compared to most species, as cells divide DNA is slowly broken down, until cancer or organ failure or a dozen other diseases set in.
