1a) You are studying two populations of pika. You find that the population inhabit in talus (broken rocks) are greyish. Another population live in coniferous forests have black fur. When individuals from each population are brought together in the lab, they produce offspring whose appearance is intermediate between the two parents. The offspring can breed and reproduce successfully with each other or pika of either parent population. You sequence three genes, Pigmentosa, Sparkly, and Zippy. For each of the three genes, the two populations differ from each other at a few nucleotides (<1%). Why is it hard to determine if these two pika populations belong to the same species or are two different species? In your answer/argument, refer to at least two pieces of evidence from the above scenario. Note, we are NOT asking you to determine if these are the same species or not 1b) We are sure that our closest living relatives are chimpanzees. There is a saying that humans evolved from chimpanzees. Explain why this is not an accurate view of human evolution. In your answer: be sure to indicate what misconceptions about evolution this view illustrates, and explain why there are physical similarities and differences between humans and chimpanzees (do NOT list the differences, just explain why/how they exist)
