Humans are affecting the evolution of animals and plants

Like in a theatre where actors interact to perform the script of a given play, species on Earth interact with each other in an ecological arena, interpreting millions of years of evolution. The famous ecologist G.E. Hutchinson made that analogy back in 1965, calling attention... click to read more

Knowledge of predator-prey relationships is necessary to better understand ancient ecosystems, like the 131-120 million-year-old Jehol Biota in northeastern China. Through... click to read more
