Is the species a generalist or a specialist and how does this niche impact the species of the wild.  The giant panda, native to China, and the raccoon, native to North America, share a common ancestor. However, their current status in the wild is anything but common.

Synthesis:  How does reproductive isolation differ in sympatric modes and allopatric modes of speciation?

What is an example of how migration causes changes in gene frequencies?         Genetic material can become lost over time due to lack of reproduction when animals migrate.         When animals migrate, their genes mutate on their own, changing the frequency that a gene allele shows up.         When animals migrate, the mating becomes less random, causing inbreeding and, therefore, shifts in the proportion of alleles.         Seeds of plants are carried to different locations and introduced to a new population, adding their own genetic material and, therefore, changing gene frequencies.

Why climate change is crucial to the survival in the population of sea turtles? Discuss.
