Fossil
|
Remnants of a organism from the past
|
|
|
Adaptation
|
a mutation that an organism is born with that helps the species survive to reproduce
|
|
|
Selective Breeding
|
breeding for wanted or necessary traits (dogs, horses)
|
|
|
Variation
|
Many traits in a gene pool
|
|
|
Overproduction
|
having more offspring that will survive so that more will survive to reproduce (if a monkey has 16 babies and only 8 survive, if the monkey had had 8 babies less would survive
|
|
|

|
Darwinism

|
|
speciation
|
When one part of the species is separated from the rest of the species and changes so much it can no longer mate

|
having exadurated traits that help get a mate (and reproduce)
|
|
|
Charles Darwin

|
|
|
Theory of Evolution
|
species gradually changed over many generations and became better adapter to the new conditions
|
|
|
What supports the theory of evolution
|
fossils, bacteria, genes
|
|
|
How does a new species form?
|
1. geographic isolation
2. random mutations |
