There is a dizzying diversity of species on our planet. From genetic evidence we know that all of those species evolved from a single ancient ancestor. But how does one species split into many? Through the evolutionary process of speciation—which begins when populations become isolated by changes in geography or by shifts in behavior so that they no longer interbreed. The speciation process is the basis of earth’s biodiversity. Filmed and photographed by Tim Laman. Explore more at www.birdsofparadiseproject.org
