Darwin
Who was a naturalist who studied plants and animals?
Charles Darwin
Those with advantageous traits survive.
Survival
True or false: Mutations can lead to new traits that may help or hurt survival.
True
Why does convergent evolution happen?
Adapting to similar environments
The process by which species change over time
Evolution
How long did he travel on the Beagle?
5 years
Organisms compete for resources.
Competition
What kind of mutation is this?
The dog went to the park.
The brown dog went to the park.
Insertion
Evolution occurs when related species become more different.
Divergent evolution
The idea that organisms with beneficial traits survive and reproduce
Natural Selection
What species did he study?
Finches
Individuals in a population have different traits
Variation
Is this the definition for homologous structures or analogous structures
Structures are similar in different species
Homologous
Reminder: Analogous structures have similar functions but different origins.
Occurs when different species develop similar traits.
Convergent evolution
The study of where species live around the world
Biogeography
Their beaks
Survivors pass on their traits to the next generation.
Reproduction
What are the three types of mutations?
Substitution, deletions, insertions
What is punctuated equilibrium?
Punctuated equilibrium is a theory that evolution happens in quick bursts.
Changes in an organism's DNA that can lead to variation
Mutation
Naturalist
Physical and behavioral
Give an example for analogous structures.
Wings in birds, bats, insects
What is coevolution?
When two or more species influence each other's evolution.
The preserved remains of past organisms providing evidence of evolution
Fossil
