Your assumption that humans somehow live longer than most other animals seems to be a misconception. You see, it is not only humans, but most large animals around our size, and larger, which live longer (for example, sea turtles live up to 200 years).

Source: Wikipedia.org article, adapted under https://creativecommons.org/licenses/... license. An autosome is a chromosome that is not an allosome (a sex chromosome). Autosomes appear in pairs whose members have the same form but differ from other pairs in a diploid cell, whereas members of an allosome pair may differ from one another and thereby determine sex.
Humans have a total of 46 chromosomes in each body cell; 44 of these are autosomes. You get one set of 22 autosomes from your mom and another set of 22 from your dad. It is often easier to think about our autosomes in pairs because even though we have 44 autosomes, we actually only have 22 types. We have two copies of each type of autosome, one from each parent. Two chromosomes of the same type, called homologous chromosomes, are the same size and shape and have the same genes. Our paired autosomes are numbered 1 through 22.
