Introduction:
Speciation is the process by which species evolve from an ancestral population. The rate of speciation (although slow) depends on a number of factors such as diet, dispersal ability, and sexual selection.

- The crab spider, Thomisus spectabilis, sits on flowers and preys upon visiting honeybees. Do honeybees distinguish between flowers that have crab spiders and flowers that do not? To test this, Heiling et al. (2003) gave 34 bees a choice between 2 flowers: one with, and one without a crab spider. In 24 of the 34 trials, the bees picked the flower that had the spider. In the other trials, the bees chose the spiderless flower. With these data, carry out the appropriate hypothesis test (one- or two-tailed), using the normal approximation to the binomial distribution to determine Z. For a one-tailed test, use the formula =(1-NORM.DIST(Z,0,1,TRUE) in Excel calculate P. For a two-tailed test, use the formula =2(1-NORM.DIST(Z,0,1,TRUE). State your answer for the value of P to three decimal places, and include the leading zero. Do all of the math in Excel DO NOT round the value of Z. Substitute the cell (e.g. B1) for Z in the formula for P.arrow_forwardhow does natural selection and adaptation happen in pests with the use of pesticides?arrow_forwardIf you designed an experiment to determine how temperature and the species composition of seeds affect the growth and reproduction of seed-eating birds, what would be the independent and dependent variables?arrow_forward
