Gregor Mendel
Charles Darwin
Albert Einstein

The beaks changed over time because of the scarceness (small amount) of food.

What is the advantage to selectively breeding dogs?
Dogs can be bred with very specific traits such as size, personality and temperament.
Humans developed purebred
dogs to live and breed, so genetic problems continue to be passed on from parent to offspring-genetic
problems.
Genetic modification occurs when the genetic
material, the DNA, is changed to produce a desired trait.
Sharks are colored white on the underside and blue or gray on top. How is this trait an advantage for them?
It allows them to stay camouflaged on top by looking like the water.
It allows them to stay camouflaged on the bottom by looking like the light on the surface.
