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.

"It was completely unexpected," he says. "We sat there banging our heads against the wall. Darwin's hypothesis has been with us for so long, how can it not be right?"

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.
