Darwin's Natural Selection Worksheet Read the following situations below and identify the 5 points of Darwin's natural selection. There are 2 types of worms: worms that eat at night (nocturnal) and worms that eat during the day (diurnal). The birds eat during the day and seem to be eating ONLY the diurnal worms. The nocturnal worms are in their burrows during this time. Each spring when the worms reproduce, they have about 500 babies but only 100 of these 500 ever become old enough to reproduce. 1) a. What worm has natural selection selected AGAINST? Darwin's 5 points: Identify the 5 points in the scenario above. Population has variations. Some variations are favorable.. More offspring are produced than survive. Those that survive have favorable traits. A population will change over time.. 2) There are 3 types of polar bears: ones with thick coats, ones with thin coats and ones with medium coats. It is fall, soon to be winter. The temperatures are dropping rapidly and the bears must be kept warm, or they will freeze to death. Many of the bears have had ~2 cubs each but due to the extreme temperatures, many mothers only have one cub left. a. What bear will natural selection select AGAINST? Darwin's 5 points: Identify the 5 points in the scenario above. Population has variations. Some variations are favorable.. More offspring are produced than survive. Those that survive have favorable traits. A population will change over time.. 3) FOR? a. What ostrich will natural selection select AGAINST? FOR? In ostriches, there are 2 types: ones that run fast and those that run slowly. The fast birds can reach up to 40 miles an hour. Jackals love to eat ostrich, and they can reach speeds of up to 35-40 miles per hour. A flock of ostrich will lay ~ 10 eggs (each mother only lays 1), but many rodents break into the eggs and eat the fetus before they hatch. FOR?
