☆☆☆☆☆a species can gradually change into new species
The peppered moth had white bodies and wings, peppered with black. This coloration blended well into the original British countryside, hiding them from their predator the birds. Factories of the early industrial revolution covered everything with soot. Now the white stood out against the black surroundings making them easy targets for birds. Over time the white moths were wiped out. But, a few of them were darker in color, these survived and multiplied such that the white peppered moth was replaced buy the dark ones.
Black moths were selected for when the trees turned black.
the moths with the high fitness were selected for
The black moths were more fit for survival, so their phenotype frequency increased.
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.
They make the species more genetically diverse
allele frequency change Apex :)
The method an organism uses to produce offspring
the way that a species creates offspring
selecting individuals at random. Apex 8)
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.
an experiment shouldnt cause harm- apex
Which statement is ture about all adaptations
A living thing rarely repeats a behavior in exactly the same way
span the full spectrum of a population's genetic variation.-apex
