The fossil record indicates that multicellular organisms have existed longer than unicellular organisms on Earth. 7. r observations 8. Choose the two that apply. Which of the following were Darwin's two majo that led him to his theory of evolution by natural selection? A. More offspring are produced than the environment can support B. Traits that get used are passed on to the next generation C. Alleles segregate independently of one another during meiosis D. Organisms within a species vary in many traits E. Acquired characteristics are passed on to the next generation 9. The swaying of the Costa Rican leaf mantid is an example of a _ adaptation A. behavioral B. biochemical C. structural 10. Who independently, yet simultaneously, came up with the idea that traits are selected by the natural environment, presented the idea along with Darwin, but doesn't get the same amount of name recognition or credit as Darwin? A. Jean Baptiste Lamarck B. Aristotle C. Charles Lyell D. Carolus Linneaus E. Alfred Russell WallaceExplanation / Answer
6 a. Genetic engineering ( genetic engineering may or may not affect evolution. We know variations in sequence of genes serve as source 9f change. Climate change should occur that selects individuals with variations and that survive and produce more offprings).
7 b false. Unicellular organisms mainly bacteria have ruled the earth
8a more offsprings are produced than environment can support. D. Organisms within a species vary in many traits
9 a) behavioural adaptation (these are adaptations organism do to survive ie how it acts to a stimulus)
10 e. Alfred Russel wallace
