Biology 42: Lab 22 Selection & Microevolution Name ____________ Introduction: Using the Hardy-Weinberg Equation/Looking at Microevolution What are the factors that lead to evolutionary change? Using mathematical equations‚ Hardy & Weinberg in the early 20th century showed that evolutionary change – measured as changes in allele frequencies in a population from one generation to the next – will not occur unless certain kinds of “evolutionary agents” are affecting the population

Wild Animal Profiles African Elephant | Mammal. The largest living land mammal‚ the African elephant weighs 3500 to 7000 kilograms (3.5 to 7 tons) and stands 3.4 meters (11 feet) high. The elephant’s remarkable trunk serves variously as a nose‚ arm‚ hand‚ foot and multi-purpose tool. The trunk is strong enough to uproot a tree and delicate enough to pick berries‚ and it enables the elephant to reach as high as 7 meters (23 feet). Humans can hear only 20% of the vocal sounds an elephant makes;

precise conditions of temperature and precipitation can vary over small distances. Ecologists recognize at least ten different biomes. The world’s major biomes include tropical rain forest‚ tropical dry forest‚ tropical savanna‚ desert‚ temperature grassland‚ temperate woodland and shrub land‚ temperate forest‚ northwestern coniferous forest‚ boreal forest‚ and tundra. A unique set of abiotic factors‚ particularly climate and a characteristic assemblage of plants and animals define each of these biomes
