Types of Selection

Master types of selection: directional, stabilizing, disruptive & sexual. Learn about isolation mechanisms in evolution!

Sort each image or description into the correct type of selection (I put larger images below just in case the ones you are sorting are too small) Directional Selection Only the darkest moths blend in with the bark; therefore, they survive and reproduce Stabilizing Selection short tails throw off a cats balance and long tails drag on the ground. Medium tails are best Disruptive Selection large beaks can crack seeds and small beaks can pick up insects. Medium beaks can't do either Sexual Selection A female chooses the male with the best territory Geographic Isolation Darwin's finches stopped mating because they lived on separate islands Temporal Isolation Species of flowers don't mate because they accept and release pollen on different days Behavioral Isolation Species of birds don't mate because they have different mating rituals Reproductive Isolation even if two organisms could have offspring, their offspring would be infertile
