Tiny Genomes and the Origin of Complex Cells

Symbiotic bacteria that dwell within insect cells are intricately intertwined with their hosts, prompting scientists to question when these bacteria stop being bona fide organisms and become part of the cell.

A New Approach to Building the Tree of Life

More genetic data is available than ever before to help build evolutionary trees, but scientists are finding that different genes even in the same organism can tell conflicting stories.

Hunger Game: Is Honesty Between Animals Always the Best Policy?

Game theorists have developed a new model of communication among animals. It suggests evolution will produce a situation in which members of a species are honest most of the time, but not always.
