What is the theory that states that some competitors would be better equipped for survival than others and those less equipped would die.
The theory of evolution by natural selection
100
What causes evolution, according to the theory of evolution by natural selection?
Natural selection over generations
100
Bat wings, cat paws, and whale fins are an example of this
Homolgous structure
100
What is natural selection?
A process in which species that are best adapted to their environment are able to survive, reproduce and pass along their genetic information
100
True or false : populations evolve, not individuals.
True
200
What did Darwin observe on the Galapagos Islands?
The different islands all seemed to have their own slightly different species of birds that were also different than the mainland species.
200
What is the evidence for evolution? name two
Fossil record, comparative anatomy, vestigial structures, comparative embryology, comparative molecular biology, biogeography
200
How are fossils used as proof of evolution?
Fossils can show (1) modern species resemble ancient species, (2) some species have not changed much, and (3) that there are records of intermediate species
200
What is an adaptation?
Any inherited characteristic that increases an organisms chance of survival
200
What is the Hardy-Weinberg Equilibrium equation?
P2 + 2pq + q2 = 1
300
What was the name of the ship Darwin worked on as a naturalist from 1831-1836?
HMS Beagle
300
True or false: evolution happens quickly and can change in one generation
False
300
What are derived traits and ancestral traits?
Derived traits are new features that do not appear in fossils of common ancestors (such as feathers) and ancestral traits are more primitive and do appear in fossils of common ancestors (such as teeth and tails).

What adaptation do polar bears have and how does it help them?
Camouflage allows them to blend in to their surroundings
300
Explain which mouse is better adapted to this environment.
The grey mouse is better adapted to this environment. Its fur color blends in with the environment and therefore is not seen by predators.

True or False: Natural selection and evolution mean the same thing
False
400
Fill in the blank: The better an organism is adapted to its environment, the __________ its chances of survival and reproductive success/
Greater
400
How is embryology proof of evolution?
Many organisms of different species look similar during early stages of development.
400
What is mimicry?
An adaptation that harmless species exhibit that makes them look similar to harmful species.
400
If there is a population of 500 mice, and 100 mice try to leave and begin a new population, is the population in genetic equilibrium?
No there can not be immigration or emigration
500
Which principle of natural selection does this example describe: A bird laying 7 eggs every year.
Animals have more young than can survive on the available resources.
500
Name one of the principles of natural selection.
Variation among others of the same species, variations are inherited, animals have more young than resources will provide for, OR variations that contribute to reproductive success become more common in the next generation.
500
What is comparative molecular biology and how is it used to see how related 2 species are?
Comparative molecular biology involves comparing molecules (DNA or amino acids) of different species. The more similar the DNA is, the more recently they shared a common ancestor

In an environment with food that grows on trees; are animals with long legs more likely to survive than animals with short legs and why?
Yes, animals with long legs, necks or any trait that makes them taller will be more likely to survive because they have easier access to food.
