4. Which is an example of artificial selection?
-There are 4 different species of Hyena
-Red fox and Fennec Fox
-Fancy Pigeon breeds raised by Mike Tyson
-A Peacock and a Peahen
Answer: Fancy Pigeon breeds raised by Mike Tyson
Explanation:
Having 4 species of hyena and having a Red fox and Fennec fox are not artificial selection; they are natural species differences. Having a peacock and a peahen is an example of dimorphism. Fancy pigeon breeds are artificially selected for their most desirable characteristics - humans interfere with natural selection.
Answer:
Fancy Pigeon Breeds raised by Mike Tyson
Explanation:
This is because the selection is being performed by a human for artificial and cosmetic reasons and the pigeons are being bred for their "fanciness." Natural selection happens because an animal needs to adapt for survival reasons, whereas this artificial selection isn't happening "naturally" for survival reasons, only for looks, etc.
