Pre-Comp Jeopardy : Evolution

Question 1

What is speciation?

Answer 1

When a new species arises/evolves from a preexisting one

Question 2

What are the two types of speciation we talked about?

Answer 2

Allopatric, peripatric

Question 3

In asexual reproduction, _______________ is a source of genetic variation.

Answer 3

mutation

Question 4

What is an advantage of sexual reproduction?

Answer 4

Quality over quantity, more genetic variation, increased chances for variance = better adapted in case of widespread disease or disaster

Question 5

What is a disadvantage to sexual reproduction?

Answer 5

Takes a longer time, requires more energy, requires a mate

Question 6

When is it clear that speciation has occurred?

Answer 6

When the new species can no longer reproduce and create fertile offspring

Question 7

What’s the difference between anagenesis and cladogenesis?

Answer 7

Anagenesis is the loss of the preexisting species, cladogenesis is the arising of a new species while the preexisting one is still alive

Question 8

How can the theory of evolution be used to argue or predict that there was once a single common ancestor to all eukaryotic organisms?

Answer 8

If everything is evolving outward, if we trace back along the evolutionary pathway billions of years back, then it would make sense that everything originated from one point.
