Survival of the Smartest
Which scientist developed the theory of evolution by natural selection?
Charles Darwin
Darwin noticed finches had different beak shaped adapted to different what?
food sources
What are fossils?
What is the difference between Camouflage and Mimicry?
Camouflage is to blend in with the surroundings and mimicry is to look like another organisms to avoid or hide from prey.
What is the type of evidence that includes comparing bone structures of different animals?
Comparative anatomy
Traits that help organisms survive are called this
Adaptations
What is it called when humans choose which traits organisms will have?
Artifical Selection
What are homologous structures?
Structures that are similar due to common ancestry but have different functions
What is Embryology?
What is it called when all members of a species die out at one time.
Mass extinction
what is the process where organisms better apated to their environment survive and reproduce called?
Natural Selection
What are the 3 types of adaptations?
What are analogous structures?
Structures that have similar functions but different structures
What is the Geological time scale?
A timeline of Earth's history found in layers of rock
Fossils found on lower levels of Earth's layers are newer or older?
Older
What must exist for natural selection to occur?
Variation
A giraffe with a longer neck can reach more food and survive this is an example of what concept.
Adaptation
Comparing DNA between species provides what kind of evidence
molecular evidence (genetic)
What is the difference between gradualism and punctuated equlilbrium?
Gradualism is a slow change over time and punctuated equilibrium is a sudden change follow by a time of slow change
Natural Selection. A mutation becomes favorable and eventually dominates the population.
What does "survival of the fittest" mean
best adapted organisms are more likley to survive and reproduce
Mutation
What is Divergent Evolution?
Evolution through one common ancestor breaking off to form many different organisms
What is Convergent Evolution?
Organisms evolving from different ancestors but evolve similarly due to environmental factors
Behavioral Adaptation
