Zakaria comes from the island blue. He is blue, he travels to island green and mates- what is this mechanism?
gene flow
genetic drift
non-random mating
natural selection
18
What best fits the theory of Natural Selection?
Animals better adapted to environment, survive and reproduce
Features that enable survival in a habitat
A feature used more is stronger. One not used disappears.
Adaptations that are passed on to offspring.

chance
adaptations
selection

adapations
variations
accumations
accommodations
