Q

4 key points of natural selection

A

More offspring made then survive
Individuals have variation
Offspring of survivors make up most of the new generation

A

DNA, Atp, similar enzymes

18
Q

What is stabilizing selection

A

Selection that favors medium phenotype

19
Q

What is directional selection

A

Favors one extrem phenotype

20
Q

What is disruptive selection

A

Favors either extreme phenotype

21
Q

What is gradualism

A

Originate due to gradual changes

22
Q

What is punctuated equilibriums

A

Originate in short rapid bursts then long periods

23
Q

What is adaptive radiation

A

One species evolves into many different species in habitats

24
Q

What is divergent evolution

A

When species that were similar become different

25
Q

What is convergent evolution

A

Organisms in different places evolve similar traits due to natural selection
