In development, it’s all about the timing

Closely related organisms share most of their genes, but these similarities belie major differences in behavior, intelligence, and physical appearance. Scientists are beginning to appreciate that the timing of the events that happen during development plays a decisive role in defining an organism. Now, a team of scientists has identified LIN-42 as a key regulator of developmental timing, governing a broad range of events throughout maturation.
