The Presence of the Frontal Opercula in Homo naledi

When it comes to the evolution of the human brain, size isn't everything. In fact, shape is a huge determinant. A new study from Hawks in PNAS suggests that morphology may proceeded size in the evolution of hominin brains. Hawks and team performed a comparative anatomy study of Homo and Australopithecus brains based on endocasts. Endocasts... Continue Reading →

Well this is kind of embarrassing but inconsequential... Gary Sawyer and Mike Smith at the AMNH began a reconstruction of Lucy with help from Scott Williams from NYU and noticed that one of the vertebra fragments is smaller than the other! A comparative study to other animal's vertebrae show that it more closely resembles a baboon's vertebrae.  This... Continue Reading →

Can I See Your Fingers Please?

That is what University of Liverpool's Emma Nelson probably would have said if she were to meet our hominan ancestors in person. Known to hold true in anthropoids (humans, apes and monkeys), the index (second digit) to ring (fourth digit) fingers ratio or 2D:4D is an indication of how much an individual were exposed to...

Homo floresiensis Walked Out of Africa

Skull of LB1 (Homo floresiensis, or the hobbit) Photo from Science Museum New analysis by a team led by Australian National University doctoral student Debbie Argue showed that Homo floresiensis, nicknamed hobbits, were early hominin and walked out of Africa to Flores. Their findings supports the argument that Homo floresiensis had a unique wrist anatomy... Continue Reading →

Homo heidelbergensis Ear Anatomy Indicates They Could Have Heard The Same Frequency of Sounds As Modern Humans

Pinpointing when language became a prevalent trait during human evolution has been tricky. Last fall we read a paper which documented that Neandertals have the same FOXP2 sequence as modern humans. FOXP2 is a transcription factor associated with language. Two recent papers have shown that chimpanzees and humans have very similar structures in the brain... Continue Reading →
