What is artificial selection (selective breeding)?
When u take one organism like a dog and mix it with other traits you want in a dog or an organism and breeds them together
It can be used to increase the amount of food by making more food and what you like in that food so you can have more of it
Adaptation: Bear sleeping in a cave during the winter months
Adaption: birds flying south for the winter
