Evolution
|
CHANGES in the gene pool over time
|
|
|
Adaptation
|
The traits that survive when the gene pool of a population changes in repsonse to its environment
|
|
|
Charles Darwin
|
Father of Evolution |
|
|
Competition
|
When organisms are going after the same resource. (food, land)
|
|
|
Diversity
|
different kinds of organisms or different kinds of alleles for the same trait.
|
|
|
Fossils
|
the trace remains of organisms.
|
|
|
What is the best evidence of evolution?
|
Fossils.
|
|
|
Galapagos Islands
|
Islands where Charles Darwin observed the adaptations of finches.
|
|
|
Habitat
|
A place where an organism lives.
|
|
|
Homologous Structures
|
Anatomical Structures that do the same job in different species.
|
|
|
Steps of Natural Selection
|
1. Overpopulation 2. Genetic Variation 3. Selection 4. Adaptation |
|
|
Species
|
A group of similar organisms that can reproduce with each other.
|
|
|
Variation
|
Differences within the same species (male and female humans)
|
|
|
Five ways micro-evolution can occur
|
