The idea that life on earth has changed over time due to hereditary changes in DNA

Explanation:

1) Although we may have descended from apes, evolutionary theory is about how we evolved through changes in DNA and through, well, evolution.

2) Extinction actually can cause a major issue in a food chain, causing all animals that ate the extinct animal to possibly die, and all the animals that were eaten by the extinct species could overpopulate.

3) Biology and religion are two very touchy topics, however, evolution is backed by many years of evidence and proof. Religion is touchy.

4) Yes, we all began changing due to DNA and hereditary changes.

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.
