We predict that Homo heidelbergensis and Homo neanderthalensis had brains with approximately 80 billion neurons, within the range of variation found in modern Homo sapiens. We then used those scaling rules and published estimated brain volumes for various hominin species to predict the numbers of neurons that composed their brains. The conformity of great apes and humans to the linear cellular scaling rules that apply to other primates that diverged earlier in primate evolution indicates that prehistoric Homo species as well as other hominins must have had brains that conformed to the same scaling rules, irrespective of their body size.

Our results suggest that the brains of great apes also scale linearly in their numbers of neurons like other primate brains, including humans. To investigate whether the brain of great apes also conforms to the primate cellular scaling rules identified previously, we determine the numbers of neuronal and other cells that compose the orangutan and gorilla cerebella, use these numbers to calculate the size of the brain and of the cerebral cortex expected for these species, and show that these match the sizes described in the literature. In contrast to the view that the human brain is special in its size, we have suggested that it is the great apes that might have evolved bodies that are unusually large, on the basis of our recent finding that the cellular composition of the human brain matches that expected for a primate brain of its size, making the human brain a linearly scaled-up primate brain in its number of cells. This discrepancy has been used as evidence that the human brain is about 3 times larger than it should be for a primate species of its body size. It does not store any personal data.Gorillas and orangutans are primates at least as large as humans, but their brains amount to about one third of the size of the human brain.

Then, with the family’s head of household ensuring that the road is secure, the entire family, from moms to children, casually crosses across, with the courageous male being the last to emerge from the bushes on the other side of the road. Even a fully loaded truck barreling towards him doesn’t appear to bother him in the least.

However, as soon as the massive guy reaches the center of the road, he stuns there, full of confidence, despite the fact that he is being seen by so many people.

Everyone was ecstatic at such a sight, but they had no clue what the enormous ape was up to. They were on a forest road with their cameras turned on when a big silverback gorilla emerged from the woods. When the team observed the once-in-a-lifetime moment, they were in Kahuzi-Biega National Park.

The filmmakers accidentally caught a moment that shows how protective these majestic animals are when comes to their families!

When wildlife photographer, Gordon Buchanan, and his BBC crew traveled to the Democratic Republic of the Congo, they all hoped for some unique encounters with the endangered silverback gorillas.
