☆☆☆☆☆Artificial Selection Answer Artificial Selection is the breeding of certain traits (better traits) over other traits. For example, breeding a good male horse with excellent racing qualities with a healthy female horse so that the offspring will have the desired traits such as the racing qualities. Another example is breeding good size fruits or vegetable together to keep on getting the good size.
Selection done by humans looking to maximize traits in animals under domestication. These traits are not always for the benefit of the organism though. Men raise these animals and mate the ones they think will breed true for a man favored trait and cull the rest of the organisms by killing them, or by not allowing them to breed.
a species can gradually change into new species
sex cells
random chance.
found how to get product for growt hair
Food supply
There must be genetic variation in the population
The system must not be in hardy-weinberg equilibrium.
resources must be limited in the ecosystem
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.
When there is low gene flow
When there is no selective pressure
When there is a bottleneck
A scientist should observe the natural world without changing or destroying it.
The method an organism uses to produce offspring
the way that a species creates offspring
Random processes are not part of the theory of evolution by natural selection.
A structure that is a member of another structure is a structure within a structure.
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.
Each individual in a population behaves in a slightly different manner.
