1. Imagine you are a scientist trying to determine the evolutionary relationship between 2 different groups of snakes. The first group of snakes lives in North America, the second lives in Africs. The 2 groups are very structurally similar, although North American snakes are brown and white and the African snakes are green. The two groups of snakes have nearly identical chromosome structures. Do you think these 2 groups of snakes share a common ancestor? Why or why not?

2. Would you classify the 2 groups of snakes as the same species? Why or why not?

1. Yes, I would conclude that they have a common ancestor, but you have to state the time frame, say they don't have a common ancestor going back thirty thousand years, but four hundred thousand years ago they do have a common ancestor. That common ancestor would be located on the point that the continents seperated, and they evolved along the same lines, but slightly different.
2. This question is unancerable, because to be the same species they have to be able to mate with eachother and have offspringthat can have other offspring, since you didn't give such info, we can't tell.
