The structure of DNA is stable but it can undergo mutation once in a while to provide the raw materials for natural selection to act upon.
lol from Kaplan huh?
They can produce enzymes under some conditions but not all. this is natural selection because producing them themselves makes it easier for them to stay alive.
Variation within species allows death to be a selector of survivors.
Natural selection with modification of traits. He could explain natural selection, however he had no explanation for modification of the traits from generation to generation (this had to wait for Gregor Mendel's theory of genetics, and the later discovery of nucleic acids and Watson and Crick's study of DNA to explain the storage of genetic information chemically).
Natural selection may ultimately be his downfall.
Yes, that would be called the Homologous structure, and that changes in natural selection.

How it can change in response to its enviroment
Yes, it is true.
To attract females. Natural Selection*
eszter likes boys <3
Knowledge to the structure of DNA.
natural selection and common descent
According to science, natural selection chooses the best features for the best survival. When those processes do not occur for some reason, the species does not survive.
