Question

Marianne is comparing two animals: a fruit fly and a fruit bat. She asks, "Do a fruit fly and a fruit bat share a common ancestor in their evolutionary history?" According to evolutionary theory, what is the answer to Marianne's question?

Answer 1

The answer is; YES

All organisms share one common ancestor in the beginning of life. Different species have branched at different times from common ancestors hence he evolutionary tree looks like tree called a cladogram. The nodes represent the common ancestry while branches depict divergence. Therefore even fruit flies and the fruit bats even though they do not belong to the same species shared a common ancestor at one time in history.
