Study suggests survival may not always be about competition
Undergraduate student and postdoctoral researcher, during studies that ultimately challenged one of Darwin's hypotheses related to competition. Researchers' experiments on fresh-water green algae failed to support Darwin's hypothesis that closely related species will compete for resources more strongly with one another than with distant relatives.

Experiments on fresh-water green algae failed to support Darwin's hypothesis that closely related species exhibit the highest levels of competition for food and other resources because they occupy similar ecological niches.
