What did Charles Lyell observe and come up with?
Earth is a few thousand years old
all populations evolve through natural selection
the human population will outgrow the available food supply

There is a species of squirrel that has adapted to ONLY eat one kind of berry in order to survive. Recently bears have came into the area and are eating a great number of the berries. The squirrel population will likely do what in response to this?
Decrease
Increase
Stay the Same
Mutate to have wings
An inherited trait that increases an organisms chance for survival is called what?
Genes
Genetic Drift
Adaptation
Heredity
The genes that are carried by all members of a population is considered that populations......

Genotype
Gene Pool
What is a non-adaptive trait?
a trait that does not help an organism surive and reproduce.
a trait that causes animals to be come more fit
a trait that allows animals to camoflauge
it causes a mutation
Can mutations be passed down to offspring?
Yes
No
Where do adaptations come from?
The individual organism decides to adapt
Mutations that give an organism an advantage in its environment
Genetic recombination during meiosis
Both mutations and genetic recombination are sources of adaptation
