The four points of darwin's theory 1) organisms produce more offspring than can survive 2) variations exist within populations 3) Some variations are more advantageous than others 4) overtime, those with advantageous variations survive to reproduce
evolution the change in hereditary features of a population over time.
mutation permanent change in gene or chromosome
fossil evidence fossils provide information about condition on earth. C

The DNA sequences found in 2 different species are 95% the same. This suggest that the species may have similar evolutionary histories
The fact that healthy deer can outrun timber wolves is an example of natural selection
A maple tree releases hundreds of seeds in a single season. this is an example of over production
The shark has changed very little in the last 50 million years. Which statement best explains why The shark is well adapted to its relatively unchanged environment
compounds like the pesticide DDT may bring about the evolution of new strains or organisms by acting as a a selecting agent
