Hoje é só actividade. Uma notícia no site da Discovery diz o seguinte:

Chimpanzees share 99.4 percent of functionally important DNA with humans and belong in our genus, Homo, according to a recent genetic study.
Previous studies put the genetic similarity between humans and chimps at 95 to 99 percent, so the new figure suggests chimps and humans are even more closely related than previously thought.
[...]The researchers then took the DNA data and estimated genetic evolution over time. They determined that humans and chimps shared a common ancestor between 4 and 7 million years ago. That ancestor diverged from gorillas 6 to 7 million years ago.
"Chimps are more like a human than a gorilla," said Goodman. [...] Goodman added, "In terms of culture, social behavior, language and other factors, we share many things in common with chimpanzees."


A BBC acrescenta:
"Humans, or Homo sapiens to give the species its scientific name, are the only living organism in the genus at the moment - although some extinct creatures such as Neanderthals (Homo Neanderthalis) also occupy the same grouping.
[...]Dr Wildman said: "You could say that humans and chimps are as similar to one another as say horses and donkeys.
[...]The Detroit team says its work supports the idea that all living apes should occupy the higher taxonomic grouping Hominidae, and that three species be established under the Homo genus: one would be Homo (Homo) sapiens, or humans; the second would be Homo (Pan) troglodytes, or common chimpanzees, and the third would be Homo (Pan) paniscus, or bonobos. Not all scientists will accept the new classification."

Seja como for. Eu cá o que sei é que gosto de salientar a nossa parecença com estes bichos, especialmente em argumentos sobre a "superioridade Humana".
