Watch The Video on Youtube And then answer each question with 6-10 sentence response.

“The Salamander’s Tale.”

For our purposes here, this means that we create an arbitrary division in time or space to create species. At what point in time or space do the salamander populations described in the video exist as truly separate species? Dawkins goes further to explain that discontinuous thinking poses problems in a host of other areas, such as race, politics, or abortion. Thus, the odd reference to abortion in the video. It’s unfortunate that the video was edited to exclude the longer discussion of discontinuous thinking but the reference to abortion remains. Because of this, I want you to disregard the reference to abortion and focus on the other aspects of the video. 

1.What are ring-species and how can they improve our understanding of biological evolution?

2. What is the evidence used in this case study? What conditions limit gene flow among the salamander populations?
