01 What are Darwin's four observation Concesing natural Selection ? Ans #abservaton 10%- - Members of a population often then very greatly in their traits #observation and Trait are inherited for parents - 20 offspring obsenection and All species are capable of producing sose offspring than the environmeut can support #obsequation 4th owing Eesouces, many of these to lack of food or other sharing do not survite. Ans lost and briefly exprain which each one with an example . ) In this example a group of mice with heritable variation in fear color (black ustan) has just moved Por to a new career where the rocks are black 4 This environment Features hawks, which like to eat mice and can see than tan once more easily than the blace oneg against the black rock. & Because the books can see and catch the tan mice more easily, a relatively foroge Frection of the tan mive are eaten, while a much smaller traction of the black mire are

eaten. If we look at the ratio of black mice to tan mice is the Gloroiving (not eaten) group, it coill be ligher than in the starting population. - 4) en colon is a besofable toast (one that can be passed from poreut to child, so, the Prcreased Laction of black mice is the surviving group means an pocreased Fraction of brack Gaby mice Pr the next generasi - After the serccal generation of selection the population might be made up almost entirely of black nice. This change in the heritable Features of the population is an example of evolution. Ans How does satural Selection impact impact evolution or Natural selection lead to evolutionary Change when lodividuals with certain charactée stics have a greater survival.or reproductive rate than other posdividuals Por a population and pass on these inheritable genetic Characteristics to their offspring ,
