Which type of moth is more likely to survive in a forest of trees with silver bark: a silver moth or a black moth?

What is binomial nomenclature

What is B-moose
400
The structure of an animals body that allows it to solve problems related to survival
What is body plan
400
survival of the fittest; the organisms that have adapted the best are the ones that will survive and reproduce
What is natural selection
400
The process of natural selection producing a new species out of existing species over thousands or millions of years
What is speciation
400
Describe one way in which natural selection differs from artificial selection.
What is When humans pick and choose what traits they want later generations of organisms to have. Natural selection means that pressure within the environment favor the survival of individuals with certain traits over individuals who lack those traits.
