Textbook Question
Chapter 15, Problem 4TS
Both Darwin and Wallace, while observing life on islands, concluded that natural selection is the mechanism for biological evolution. The Hawaiian and nearby islands once had at least 50 species of honeycreepers, and they lived nowhere else on Earth.
Natural selection occurs everywhere and in all species. What characteristics of islands allow the outcome of natural selection to be so obvious.

From the natural population, 20 plants are taken into the laboratory and developed into separate true-breeding lines by self- fertilization-with selection for high, low, or medium number of seeds-for 10 generations. The average variance in the tenth generation in each of the 20 sets is about equal and averages 5.8 across all the sets. Estimate the broad-sense heritability for seed number in this population.
