3 evolution based questions

1. If we maintain a strict biological definition of “species”, H. sapiens and H. neanderthalensiswere NOT separate species as they successfully interbred. What impact might this information have on assigning a date to the origin of humans? Does this change your definition of “human”? Why or why not?

2. Select one of the topics (Homology or Central Dogma) and describe how the scientific method was employed in the study of evolution. Be sure to include the steps of the scientific method and how they were used in your particular example.

3. Search the Internet for examples where knowledge of evolution has informed modern medicine, or other fields of biology such as anatomy, embryology, or genetics. Be sure to thoroughly explain how evolution helped to inform this particular disease/research/field. Include a citation.

Answers have no specific guidelines. Any length or word count will be fine.
