Document Summary
***-biological species concept- when two individuals in a population mate and produce vial species in nature (not a zoo or laboratory). Book definition- definition of a species as a group of populations whose members have the potential to interbreed in nature and produce viable, fertile offspring, but do not produce viable, fertile offspring with members of other such groups. If two animals come into contact with each other from different geographic regions and mates to form a hybrid, they most likely had a very common ancestor. Regardless of the breed, dogs can mate and make dogs. People look different because for thousands of years, people have been geographically separated. So people have diverged genetically over hundreds and thousands of generations. Populations were isolated from one another for a long period of time. Now we are starting to change that, and mix genotypes due to airplanes and ship and slowly we"re making a new genotype.
