☆☆☆☆☆Gene flow is genes moving between two populations.
the transfer of genes from one gene pool to another
two populations transferring genes
Vestigial structures do not harm the organism. Nature selects against only harmful traits.
It tells you when the animal that made a fossil was alive.
Radio carbon dating proves scientifically the age of a given material. If a fossil is found embedded in material that is x number of years old and a similar fossil is found x number of years older or younger then we can surmise the evolution of that species. There are thousands of examples of theoretical evolution using this method.
They are thought to have separate paths of evolutionary development.
They developed along different evolutionary paths.
They had independent evolutionary development.
When there is low gene flow
When there is no selective pressure
When there is a bottleneck
Natural selection occurs when four conditions are met:
1. There is variation among individuals.
2. That variation is at least partially heritable.
3. That variation is linked to differential reproductive success.
4. More individuals are born than can survive and reproduce.
The proteins in the amino-acids might have been responsible for the change in the hemoglobin between gorillas and humans.
evolution is considered a theory and not a hypothesis or law because there is no real proof or evidence to prove evolution.

The allele frequency does not change.
They can produce fertile offspring.
