New Human Ancestor Species Found

• Researchers in the Philippines announced that they have discovered a species of ancient human previously unknown to science named Homo luzonensis.

About:

• Names: The species is dubbed Homo luzonensis, after the island of Luzon in Philippines.

• Site of discovery: The researchers from France, the Philippines and Australia found the remains in the Callo Cave, where a bone dating back 67,000 years was discovered in 2007. Thus it was initially named Callao Man.

• Timeline: It lived on the island of Luzon in Philippines at least 50,000 to 67,000 years ago.

Key features:

• The hominin has been identified from a total of seven teeth and six small bones.

• The fossils unearthed suggests that the small-bodied hominin were less than 4 feet tall and most likely walked upright

• It is not a direct ancestor of modern day humans, but rather a distant ancient relative.

• Luzonensis also has curved finger and toe bones, suggesting climbing may have been an important part of its behaviour.
