The white tailed dear is a medium sized dear that is native to the U.S, Canada, Mexico, Central America and South America. They are found in croplands, hardwoods, and pasture lands and they are usually around and/or with, fawns.
Their closest relatives are the Mule Deer, Moose, Elk and Caribou.
All their families are herbivores and ruminants. Their stomachs have four chambers and they all have all antlers.
The skeleton of the white tailed deer.
Their bone structures are quite similar which is proof of evolution because one was before the other.
Vestigial structures are genetically determined structures that have lost some or all of their ancestral functions.
It passes through the rumen to the omasum where water is removed. Finally, the food enters the last chamber, the abomasum, where it is sent on to the small intestine where the nutrients in the food are absorbed.
A transitional fossil is any fossilized remains of a life form that exhibits traits common to both an ancestral group and its derived descendant group and it shows the intermediate states between an ancestral form and that of its descendants.
From bottom to top, the embryo is the start of the deer, as it grows, and the final stage of the embryo.
Comparative embryology is used to show how all animals are related and scientists have proven that embryos of different animals shows similarities which implies that they share a common origin.
