Decoding Evolution of Large Brains in Primates Helps Study Human Traces

Reconstruction of ancient kiwi-sized primate skulls helped University of Florida researchers to solve an age-old miystery of evolution of large brains in apes into human species. University of Florida paleontologists found clues in lemur-like primate skulls from the tropical forests of Wyoming about 50 million years ago, thought to be a link between primitive and advanced primates. Arianna Harrington, a ...

Monkeys Share Thirst for Knowledge Just Like Humans: Study

Monkeys are notoriously curious, going by new research that shows how eager they are to gain new information, even if it means no immediate benefits as their brain indicates similar brain structure like humans in a region called the Orbitofrontal cortex, or OFC. The study, by researchers at the University of Rochester and Columbia University, shows that rhesus macaques have ...

Evolution: Why humans are affected less by retroviral infections than other animals?

The proportion of humans infected with retroviruses is less when compared with other animals as we have fewer remnants of viral DNA in our genes, said a new research. Attributing this phenomenon to reduced exposure to blood-borne viruses as humans evolved to use tools rather than biting during violent conflict and the hunting of animals, the researchers said, “One reason ...

How Humans Evolved Stronger Than Other Species? It’s in Gut Bacteria, says study

How human species thrived and evolved stronger than other species to be what they are now? A new study has found that microbes residing within the guts of our ancestors helped the species evolve into more stable and resilient populations. The human race ancestors were robust enough to handle environmental changes and the natural disasters they encountered, noted the study. To ...

Crows are Much Smarter Than Previously Thought: Study

When trained, crows can easily identify items by colour, shape and number of single samples as a matter of fact, that is as good as humans in terms of the so called ‘high order’ abstract reasoning process. The findings show that birds are much smarter than previously thought. “The results shatter the notion that sophisticated forms of cognition can only ...
