Species' Evolutionary Choice: Disperse Or Adapt?

Dispersal and adaptation are two fundamental evolutionary strategies available to species given an environment. Generalists, like dandelions, send their offspring far and wide. Specialists, like alpine flowers, adapt to the conditions of a particular place. Ecologists have typically modeled these two strategies, and the selective pressures that trigger them, by holding one strategy fixed and watching how the other evolves. New research published in the journal Evolution illustrates the dramatic interplay during the co-evolution of dispersal and adaptation strategies. read more
