4 points of natural selection
Students read an article and watch a video to learn more about the four points of Darwin's natural selection. Students add the main ideas to their brainstorming document and then use the document to develop a Mind Map. Extend In groups, students create a comic strip about the four points of natural selection and share it with their peers.* Evaluate 1 pt. According to the theory of natural selection, some individuals are more likely than others to survive and reproduce because they: pass on to their offspring their newly acquired traits. are better adapted to their environment than others and will pass on those adaptations to future offspring. do not pass on newly acquired traits.Figure 19.3B. 1 19.3 B. 1: Types of natural selection: Different types of natural selection can impact the distribution of phenotypes within a population.In (a) stabilizing selection, an average phenotype is favored.In (b) directional selection, a change in the environment shifts the spectrum of phenotypes observed.In (c) diversifying selection ...

Natural selection, process in which an organism adapts to its environment through selectively reproducing changes in its genotype.Natural selection is a mechanism, or cause, of evolution. Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations. Random mutations are the initial cause of new heritable traits. For example, a rabbit can't choose to have a different fur color.

In short, Darwin’s theory of evolution is the process of natural selection by which nature selects the fittest, best-adapted organisms to reproduce, multiply ... Natural selection. Natural selection is a process by which a species changes over time in response to changes in the environment, or competition between organisms, in order for the species to ...Darwin's process of natural selection has four components. Variation. Organisms (within populations) show individual variations in appearance and behavior. Domain. Some traits are consistently passed down from parents to offspring. High population growth. Differential survival and reproduction.A third key point is that while the variations occur on the genetic level in a random fashion, natural selection as a process does not occur by chance. Natural selection occurs as a result of the interaction between the environment and the population. It is on this level that the first two key points described above converge.... four giraffes stand in savannah, Kenya, Masai Mara National Park. blickwinkel/F. Stober/Alamy.

W. Tutt suggested that the peppered moths were an example of natural selection. He recognized that the camouflage of the light moth no longer worked in the dark forest. Dark moths live longer in a dark forest, so they had more time to breed. All living things respond to natural selection. Over 100 other species of moth were observed ...Artificial selection is the identification by humans of desirable traits in plants and animals, and the steps taken to enhance and perpetuate those traits in future generations. Artificial selection works the same way as natural selection, except that with natural selection it is nature, not human interference, that makes these decisions. john fiske elementary schoolelementary school principalmarcasite. The Darwinian Theory of Evolution is founded on two fundamental ideas: branching descent and natural selection. 1. Branching Descent: a. New species emerge from a single common descendant.
