(HS-LS4-2) Natural selection leads to adaptation that is, to a population dominated by organisms that are anatomically, behaviorally, and physiologically well suited to survive and reproduce in a specific environment. That is, the differential survival and reproduction of organisms in a population that have an advantageous heritable trait leads to an increase in the proportion of individuals in future generations that have recombination, plays in natural selection. What evidence can be found to support the theory of evolution? Students will identify the possible physical/genetic traits of humans that could decrease their population. They will explain possibilities to increase the population. Given a graphical analysis of a decreasing species population students will construct a possible explanation and a possible solution to prevent extinction. Posttest
