How do species change over geologic time? - American Geosciences Institute B) Low levels of genetic variation may make hybrid species more likely, so neither species will go extinct. Another theory is that individuals of a species could look different today if they had different genetic mutations. How is this best explained?Ducks with less webbing worked harder than ducks with more webbing to eat aquatic plants. There is some debate over whether individuals or the population adapt to change.

Individual differences with a genetic basis lead to in successive generations. What are the 2 main reasons for variation between organisms of the same species? Individuals of the same species generally \\ experience prezygotic barriers to reproduction. All rights reserved. Explanation: Species evolve over time scales/generations, and individuals that possess traits that are advantageous in the current environment can live at a higher frequency and transfer those advantageous traits on to their offspring. The most common mechanism for this is natural selection, in which individuals with beneficial heritable traits reproduce more than organisms without these traits, causing an increase in the frequency of the trait within the population. Fusce dui lectus, congue vel laoreet ac, d, congue vel laoreet ac, dictum vitae odio. Of course, the source of that female preference probably resides somewhere in the DNA, too.
