Natural Selection
In a population of organisms, a selection pressure favors the individuals whose characteristics are best-fit to survive it. Gradually, more and more of these individuals will live on and reproduce, while more and more of the others will die off (natural selection). Gradually, over millions of years, the gene pool of this ancestral species will change to that of these best-fit individuals, a process called adaptation.
To clarify, here's a hypothetical example. A population of beetles living on a rocky beach is composed of gray and yellow individuals. A species of bird new to this beach (selection pressure)appears and makes its home there. Its diet consists of beetles, so it targets the beetle population for its meals. However, the only individuals it can see are the yellow ones because the gray ones blend in with the rocky ground. As a result, fewer and fewer yellow ones are able to survive, reproduce, and generate more of their own kind, and the population becomes more and more gray. This survival of best-fit individuals is natural selection. Give it a few million years, and the yellow variety will be wiped out, while the gray variety will be thriving; a change in the gene pool has occurred (adaptation).

What modern synthesis theory states that evolution occurs through changes in the gene pool of?
population
The process of change that occurs during an organism's life to produce a more complex organism?
evolution. good luck! i had the same question.
Adaptation to a changing environment occurs most efficiently through which process?
Sexual reproduction
What process occurs when an egg cell blood and pieces of uterine lining leave the body through the vagina?
That's the process of menstruation - or a 'period'.
Where did evolution occur?
The only known instance of evolution occurring is here, on Earth. Logic dictates, however, that evolution occurs wherever there is life.
What is the name of the process of which evolution occurs?
The best answer is death.
Why is the species rather than the individual considered to evolve?
Evolution is a gradual process that occurs through natural selection. Natural mutation results in some offspring.
What is the ability of an organism to change internally and externally in relation to its environment?
The process where organisms evolve through time is called evolution. This natural phenomenon occurs as a result of changes in the environment.
What modern synthesis theory states that evolution occurs through changes in the gene pool of?
population
Is the process of change that occurs during an organisms life to produce a more complex organism.?
evolution
The smallest unit in which evolution occurs is?
The smallest unit in which evolution occurs is a population.
How does a banana brown?
This occurs through the process of oxidation.
Generally evolution by natural selection occurs quite slowly over?
Evolution through natural selection occurs slowly over millions of years. It has been hypothesized that evolution is the result of positive mutations that occur in a community of organisms that help them survive better. Evolution is essentially descent with modification.
Do all caterpillars go through metamorphosis?
by definition, all caterpillars will undergo metamorphosis into a moth or butterfly. all species of living things evolve, which is an entirely different biological process. evolution occurs during the course of many generations; no single individual undergoes evolution.
What is the name of the hypothesis that evolution occurs at an irregular rate through geologic time?
That theory is called punctuated equilibrium.
What form does chlorine occurs in nature?
it occurs as compounds, reacted with other elements, and can be separated through the process of electrolysis
Why anode gets thinner after electroplating?
because of dissolution process that occurs for anode through electroplating process
