Components of Natural Selection Classification Evolution Name: ___________________________#_____ Date. ______________________ Per. ________ Determine the correct classification for each of the listed statements. Write the number in the correct box. Statements: 1. A population of salmon contains some salmon that are stronger swimmers than others. Overproduction 2. After reaching maturity, hawks engage in an elaborate mating ritual and have offspring as a result. 3. Many rabbits do not survive because of predation by coyotes and hawks or not enough available food. 4. Rabbits that live to maturity may mate and produce offspring. Genetic Variation 5. Roaches lay many eggs. 6. Salmon that live to maturity may mate and produce offspring. 7. Roaches that live to maturity may mate and produce offspring. 8. A population of rabbits contains some rabbits with fur better camouflaged in their environment. Struggle to Survive 9. Many salmon do not survive to adulthood because of predation by bears or sharks. 10. Hawks are killed by power lines, hunters, and other predators. 11. Salmon lay many eggs in gravel beds each year before dying. 12. A population of roaches contains some pesticide-resistant roaches and some that are not resistant to pesticides. Successful Reproduction 13. Rabbits reproduce quickly and produce many offspring with each litter. 14. Many roaches do not survive because they come in contact with pesticides. 15. Some hawks have better eyesight than other hawks. 16. Hawks lay 1-3 eggs per year. Which two components are essential in order for natural selection and evolution to change the genetic composition of a species? _______________________________________________________________________
