☆☆☆☆☆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.
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.
It allows divergence to occur
It allows populations to become genetically different.
When there is low gene flow
When there is no selective pressure
When there is a bottleneck
A bipedal primate is referred to as a great ape, or a hominid.
Gene flow would increase between the two halves, and speciation would not occur
put the two groups in different enivorment apex
salmon before kangaroos
Apex is Mergus serrator and Mergus merganser.
