The four types of evidence for evolution upon which Darwin based his ideas were:
1-The geographic distribution of related species. The theory of evolution states that species evolve in geographic areas that were colonized by their ancestors.
2-The fossil record shows successions of organisms through time
3-Embryology: animal embryos in related species are very similar in the early stages of development but differentiate as they grow, thereby suggesting these species evolved from a common ancestor.
4-Comparative anatomy demonstrates physical and structural similarities between species. The species share anatomical similarities because they descend from a common ancestor (i.e., presence of homologies).
This is an emergency situation.
Calling 911 and activating Emergency Medical Services is first and foremost to
do.
Secure the victim from an unsafe
environment as much as possible without moving the victim. Do not shake the
