The Fongoli savanna in southeast Senegal offers a unique ecosystem. Temperatures can rise above 110 degrees Fahrenheit with brush fires sweeping across. The chimpanzees who live on these savannas weren't well understood. Erin Wessling at the Max Planck Institute for Evolutionary Anthropology studied these chimpanzees. She compared these chimps to forest chimpanzees. The Fongoli savanna... Continue Reading →
The Newly Discovered And Nearly Extinct Tapanuli Orangutan Species
Up to today, there were two known Orangutan species, both critically endangered. There are about 4,000 more Sumatran orangutans (Pongo abelii) than Bornean orangutans (Pongo pygmaeus) currently living in the Indonesian rainforest. A new orangutan family member, the Tapanuli orangutans (Pongo tapanuliensis), was described in a paper published Thursday in Current Biology. And with less than 800 individuals, that makes...

The Completed Bonobo Genome
The bonobo genome is sequenced. The letter reporting was recently published in Nature, and is available openly under the title, "The bonobo genome compared with the chimpanzee and human genomes." Kay Prüfer from the Max Plank Institute for Evolutionary Anthropologyis the lead author. There are some interesting preliminary comparisons such as: Bonobos and chimps have 99.6% sequence similarity... Continue Reading →
A New Primate Species From Myanmar Points To “Out Of Asia”
In the current early edition of the journal PNAS a new paper raises a suggestion that the common primate ancestor originated in Asia and not Africa through the discovery of a new species. This new 37-million-year-old fossil was discovered in the Pondaung sediment at Thamingyauk locality in Myanmar. The species has been named Afrasia djijidae based... Continue Reading →
