Question

Question 5 5 pts Why are long-term rates of evolution always much lower than short-term rates? Please check the two factors that appear to be parts of the explanation, and don't check the three that are wrong or not relevant here. Additive genetic variance gets used up by selection. Climate change -- the world is less stable now than in the past. Selection changes direction frequently. GxE interaction resists change and preserves genetic variance. Short-term weather and ecological perturbations tend to average out over longer and longer time scales.

Answer 1

The long term rates of evolution are much lower than short term rates of evolution due to

the climate change --the world is less stable now than in the past

and, the artificial selection changes direction frequently

that implies the rapid change in intensity and direction of selection in nature
