Scientists are fascinated by a 2013 find in South Africa. Discovered among a collection of 1,500 human fossils gathered in the area was Homo naledi, a primitive human estimated to have lived between 236,000 and 335,000 years ago. This puts this species in South Africa not long before Homo sapiens made its first appearance.

Although Homo naledi appears to have had a small brain, it is otherwise human in appearance, including long legs. From their research, scientists were able to determine that Homo naledi likely was a toolmaker, as well as being a good climber. They also found that this particular species likely buried its dead, something that was previously associated with a more modern development. The combination of Homo sapiens-like traits has some experts wondering if man evolved more gradually than previously assumed. Some researchers believe there was a species called Homo helmei that transitioned to the earliest Homo sapiens.

Study Connects Murder to Evolution

Humans are considered an evolved species, freed from the biological limitations of other species. Yet a small percentage of the population does eventually turn to murder, whether it’s for love, money, or due to some form of mental illness.

According to a new study, that small percentage may not be as abnormal as we think. A group of evolutionary biologists at the University of Granada studied more than four million murder records, noting the murderous tendencies of 1,024 mammalian species. The study actually found that humans are more murderous than other species.

The human link to monkeys has already been established. But man and monkey may have something more in common. New research shows that both species tend to grow more selective with their friends as they get older.

While not all humans lose their “social butterfly” tendencies as they get older, many elderly people begin to gradually isolate themselves. They may prefer to spend the evening at home watching TV to going to a get together, for instance. Or they might remain connected to a small social circle of family and friends rather than straying outside of that comfort zone to meet new people.
