Previous questions:
- Curtis Lively conducted many classic studies of sex using snails in New Zealand. In one study he found that highly disturbed habitats had the lowest proportion of sexually reproducing snails. These results are contradictory to the predictions made by the
a Tangled Bank Hypothesis
b Vicar of Bray Hypothesis
c Red Queen Hypothesis
- Lively also found high proportions of sexually reproducing snails in very stable, but highly competitive environments. These results are most consistent with the
a Red Queen Hypothesis
b Tangled Bank
c VIcar of Bray
Following up on the previous question, Lively also found that the stable, but competitive environments also had the most parasites. From this question and the previous two Lively should have concluded __ is(are) plausible explanations for the commonness of sexual reproduction in New Zealand snails.
a the Tangled Bank Hypothesis
b the Vicar of Bray Hypothesis
c the Red Queen Hypothesis
d the Red Queen and the Tangled Bank Hypotheses
e All answers are correct
