Artificial Selection
Humans breeding plants and animals to have useful traits
Comparative Embryology
Study of the similarities and differences in embryos of different species.
Gene flow
Individuals move in and out of a gene pool
Diversity of Life
There are countless varieties of countless species.
Population
Natural Selection
Difference of fitness in a group
Paleontologist
Scientist that studies fossils
Mutation
Vary the alleles in a population
Natural Selection
Living things with beneficial traits produce more offspring.
Allele Frequency
Show how many of each allele is found in the population
Camparative Anatomy
Study of similarities and differences in structures of different species.
Macroevolution
Over geologic time; results from microevolution evolution
Genetic Drift
Random changes that happened in a small population
Name two aspects of Darwin's theory
- Species change over time
- Existence in population struggled due to population growth.
Speciation
New species evolves
Analogous Structures
Structures that are similar in unrelated species.
Microevolution
Short period of time
Bottleneck Effect
Sudden decrease
Fitness is...
... the ability to survive based of a species traits.
Gradualism
Takes a long time
Vestigil Structures
No longer needed structures
Coevolution
Species is symbiotic relationships tend to evolve together.
Founder Effect
New population starts from a small group
They show the changes in animals over time.
Punctuation Equalibrium
Conditions are changing evolution happens more frequently
