O Ability to see UV light Grades lembers nferences In the 1890s, hunting reduced the northern elephant seal population to only 20 individuals. Due to conservation efforts, their population size today is above 30,000. How would the genetic diversity of the northern elephant seal population compare to the genetic diversity of the southern elephant seal population, which was not heavily hunted? * g Online sela on Periods 1 and 2 riods MP1, Highschool The northern elephant seal would have much less genetic varlation than the southern elephent seal. hool MP3, The southern elephant sea would have much less genetic variation than the northern elephant seal.

Those that are not well adapted don't survive and reproduce. An adaptation is any characteristic that increases fitness, which is defined as the ability to survive and reproduce. 2. What characteristic of the mice is an adaptation that increased their fitness? ¹ Teachers are encouraged to copy this student handout for classroom use.

Question 1 Choose the following scenario that is best matched to the idea of evolution by natural selection. 2% of individuals in a population die in a flood; the population remains large and there is no apparent pattern to the deaths O A group of birds grow to different sizes depending on their diet and their overall size is not heritable. A snowstorm arrives killing smaller birds. Some bears are born with long, sharp claws for digging tubers (roots) out of the ground and eating them. Claw length "runs in families" with some families exhibiting longer claws. A late spring kills off many bears with short claws A person experiences wrinkled fingertips in the water, but they are smooth when not in the water

QUESTION 3 Darwin's theory of natural selection explains: O The way life began. O The way evolution works at the genetic level. The way dinosaurs became extinct. O That traits within a breeding population that are adaptive to specific environmental circumstances become more numerous in that population over time.
