C- Adaptation
A variation means there is a ________ mutation
gene
What is survival of the fittest mean?
how well an organism can survive and reproduce in its environment
What is a preserved remains or traces of an organism that lived in the past?
A) fossils
B) species
C) evolution
A-fossils
TRUE OR FALSE: Evolution and natural selection are alike
TRUE
What does variation mean
any difference between individuals of the same species
What is the main difference between microevolution and macroevolution AND give an example of each
Microevolution: small gradual changes (birds have bigger bodies)
Macroevolution: big changes over time (dogs to wolves)
In the tropical rainforests, birds have evolved to eat the brightly-colored fruits. The fruits have evolved their attractive color so the birds will eat them and spread their seed.
- what is this an example of
Coevolution
Is a snail shell an example of a body or trace fossil and how do you know?

A) scientific theory
B) evolution
A- scientific theory
Evolution

- snail shell, turtle dropping, mosquito in amber, dino tracks

TRUE OR FALSE: Lamark discovered the Theory of Evolution and Darwin developed the first attempt at a scientific theory of evolution
False- other way around
Which sentence describes a mutation AND how do you know:
- Diego works with a botanist to study roses and their resistance to pests and diseases
-One of the roses he examines has a flower growing in a flower
- Most roses have thorns as protection against pests.
One of the roses he examines has a flower growing in a flower because flower growing in a flower is a harmful mutation
What is epigenetics?
The study of small changes to DNA that turn genes on or off but do not change the genetic code itself.
What are the examples of homologous structures, AND how do you know?
Human, lizard, whale, bird
What is evidence provided by the fossil record?
that organisms can change over time
What are Analogous Structures?
body parts have a similar function but different structure.
