Lab 2 Natural Selection

Question 1

Evolution by natural Selection is widespread in?

Answer 1

In the late’s 1800’s

Question 2

The main tenets of evolution are?

Answer 2

1) Species descended from ancestral species
2) Species change over time
3) Natural selection explains adaptive complexity- traits enhance fitness in the local environment.

Question 3

Variation

Answer 3

Individuals of the same species must differ in traits
Ex: Variations in Humans: height, eye color, hair texture, etc.

Question 4

Heritability

Answer 4

Traits must have a genetic basis and offspring but resemble their parents.
Ex: eye color, and height

Question 5

Differential reproduction is?

Answer 5

not random

Question 6

Differential reproduction is based on?

Answer 6

heritable variation

Question 7

Some parents leave progeny because they posses?

Answer 7

Beneficial traits, enhancing their ability to acquire resources, avoid predators, find mates, etc.
