Suppose two populations of a single species of lemur are separated for thousands of generations. The environments of the lemurs are slightly different. What will most likely happen to the two populations?
What is both populations will become new species
200
What is artificial selection
What is the breeding of plants and animals with desired traits to attempt to produce offspring with these same traits
200
What is kingdom
What is the highest level of classification of living things; humans belong to the kingdom Animalia
200

What is a moose
400
What is body plan?
What is the structure of an animal's body that allows it to solve problems related to survival
400
What is natural selection
What is survival of the fittest; the organisms that have adapted the best are the ones that will survive and reproduce
400
What is speciation
What is the process of natural selection producing a new species out of existing species over thousands or millions of years
400
Describe one way in which natural selection differs from artificial selection
What is natural selection is two plants or animals breeding and artificial selection is when humans breed plants or animals for specific trait
