a species can gradually change into new species
natural selection occurs when animals need it
The united states was not a member of the league of nations
The ability to survive and reproduce
A) natural selection ( apex (
The phenotype changed, which resulted in a black color adaptation.
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.
Why do organisms in different places have different traits (apex)
allele frequency change Apex :)
they are more likely to have individuals with an adaption
The beak could assist the bird with cracking open nuts,or attacking competitors.
The method an organism uses to produce offspring
the way that a species creates offspring
:D wee, ecosystems can have different conditions
Gene mutation causes the phenotype frequency in a population to change after each generation.
Finches developed many different adaptations. For example, one type of finch had a short strong beak meant for cracking seeds, while another had a long narrow beak for gathering food from the inside of flowers, and cacti, therefore making each species more adapted to its specific environment and more able to gather food then they would on another island with a different main food source.
Charles Darwin tried to answer why do different organisms live in different places.
Resources must be limited in the ecosystem APEX
What is the concept of natural selection
the moths with the highest fitness were selected for. (apex)
