The video segments have been carefully selected to engage students with key curriculum concepts. But as the environment changes, we may find that what was once an adaptation may no longer be useful.
This film describes natural selection and adaptation in populations of rock pocket mice living in the American Southwest. Nonetheless, Darwin is celebrated for the big ideas that he got right, including descent with modification and adaptation by natural selection.
Mice living on light-colored sand tend to have light-colored coats, while mice living on patches of dark-colored rock have mostly dark-colored coats.
This collection of science videos and media-enhanced lesson plans draws upon the powerful documentaries of public television’s award-winning natural history series, Nature. Although it is possible for evolution to occur quickly, the more rapidly the planet changes, the harder it is for evolution to keep pace and the more serious the risk of a massive rise in extinctions becomes. Understanding Adaptation. Defender: Natural Selection This game will teach you about forms of adaptation and the role they play in natural selection. Those who deny natural selection often have misunderstandings of biological adaptation. In evolutionary theory, adaptation is the biological mechanism by which organisms adjust to new environments or to changes in their current environment. Adaptations are well fitted to their function and are produced by natural selection. You will have to defend your territory by placing animals with different adaptations on your land. Natural selection implies that if organisms are surviving, they are adapted.
Your knowledge about adaptations will help you earn extra points!
Adaptation always involves a change of some sort, either in an organism or group of organisms, that is advantageous in the given environment. Natural selection, process that results in the adaptation of an organism to its environment by means of selectively reproducing changes in its genotype, or genetic constitution. So, a review of this topic is in order. Darwin, Charles: On the Origin of Species Title page of Charles Darwin's On the Origin of Species by Means of Natural Selection, 1859.
