Evolution

Humans have a nonfunctional appendix located near the junction of the small intestine and large intestine. The DNA sequence for histone proteins is highly conserved for multiple species. Most marsupials are indigenous to Australia, but marsupial species such as the opossum exist in the Americas and are not closely related to the Australian marsupials. Acquired characteristics, such as the presence of a docked tail in certain dog breeds, can he passed along to offspring.
