- Describe Thomas Malthus’s theory of human reproduction. Does it make sense for some species—say, bacteria or rabbits? What do you think makes humans different?How old was the world thought to be when Darwin began his voyage? How old is it thought to be now?It is said that sexual reproduction is selectively advantageous to asexual reproduciton. Why is the case? A. Asexual reproduction produces much more genetic diveristy than sexual reproduction B. Asexual repoduction is only half as efficient as sexual repdocution in sending ones genes into the next generation C. Sexual reproduction increases genetic diversity and consequently slows the rate of evolution D. Sexual reproduction is much faster than asexual repoduction E. Sexaul reproduction produces variation among populations which can help increase fitness for certain individuals/increase selection for favorable trait
- Which question below directly corresponds to whether Lamarck or Darwin are correct about their theories of the mechanisms of evolution? A.)
