2. There are 3 types of polar bears: bears with thick coats, bears with thin coats, and bears with medium coats. It is the fall season and will soon be winter. The temperatures are dropping quickly 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. Which bear will natural selection select AGAINST? b. Identify Darwin's 4 points in the scenario above. i. How does the population have variation? ii. Which variation is an adaptation (beneficial)? jii. How is the population overproducing? iv. Which population will descend with modification? FOR?

They pass on to their offspring new characteristics they acquired during their lifetimes. b. They are better adapted to exist in their environment than others. c. They do not pass on to their offspring new characteristics they have acquired during their lifetimes. d. They tend to produce fewer offspring than do others in the same environment.
There are three types of polar bears - ones with thick coats, ones with thin coats, and ones with medium coats. It is fall and soon it will be winter. the temperatures are dropping rapidly and the bears must be kept warm or they will freeze to death. the bears have had an average of 2 cubs each, but due to the extreme temperatures, many mother bears have only one cub left. Darwin's 2nd point is that some variations are favorable. Which of the variations would be favorable in this environment for the population of polar bears?
1. Which of these populations has all the characteristics needed to evolve by natural selection? A. a population of lizards may be brown or red. The temperature of the eggs determines the color of the baby lizards, and a brown parent lizard is equally likely to give birth to either color of offspring. B. a population of spiders includes individuals that build their webs in triangle shapes and others that build their webs in round shapes. They inherit their web-building strategies from their parents and all shapes are equally successful at catching insects. C. some gazelles are capable of running faster than others, a skill that is partially genetic Faster gazelles tend to live longer and have more offspring. A. Population A B. Population B C. Population C 2. Your friend asks you "If evolution is real, why aren't humans perfectly adapted by now! why do people still get heart disease and cancer and die?"

Which of the following is not true of natural selection? (a) natural selection acts to preserve favorable traits and eliminate unfavorable traits (b) the offspring of individuals that are better adapted to the environment will make up a larger proportion of the next generation (c) natural selection directs the course of evolution by preserving the traits acquired during an individuals lifetime (d) natural selection acts on a populations genetic variability, which arises through mutation (e) natural selection may result in changes in allele frequencies in a population

Mutations in genes produce new variations in a population. e. Some new variations are passed to the next generation.
Which of the following ideas is not included in Darwins theory? a. All organisms that have ever existed arose through evolutionary modifications of ancestral species. b. The great variety of species alive today resulted from the diversification of ancestral species. c. Natural selection drives some evolutionary change. d.
