by Laura Klappenbach in About Animals / Wildlife
Something dramatic happened to a lot of very big animals between 20,000 and 10,000 years ago. During this time period, 34 major groups of large animals died-out. Among those that disappeared, were ten species that weighted more than a ton. Giant sloths, mammoths, mastodons, giant kangaroos, and moa were just a few of the fast-vanishing fauna.

O sumiço de dezenas de gêneros de grandes mamíferos americanos (e de TODOS os bichos com mais de uma tonelada) do nosso continente provavelmente é o maior dos mistérios do fim do Pleistoceno, a Era do Gelo. Uma pesquisa recente parecia ter dado um jeito no mistério -- mas só parecia. O estudo deixa em aberto tantas perguntas quanto as que responde, ou até mais.
Que fezes, diria você. E, sim, fezes aqui é a palavra apropriada, porque a equipe capitaneada por Jacquelyn L. Gill, da Uni........ Read more »
