A new analysis supports the hypothesis that viruses are living entities that share a long evolutionary history with cells.

New research into human fossils dating back approximately two million years reveals how a hearing pattern that might have been useful in vocal communication in an open terrain.
Odetta: Long Ago, Far Away. How Many Trees Are There in the World? Mexican Donald Trump with George Lopez. New Human Species Discovered: Homo naledi. Bernie Sanders: Why 'Socialism' Isn't a Dirty Word.
Homo naledi adds a new human relative that was primitive but shared physical characteristics with modern humans. The location of the fossil bones suggests that they were deliberately disposed of underground.
Scientists have discovered a new human-like species in a burial chamber deep in a cave system in South Africa.
August 26 is World Dog Day, a good time to reflect on the very reasonable possibility that dogs enabled modern humans to outcompete Neanderthals, and also on the fact that dogs are smarter, more empathetic and more devious than you knew. These days, both ordinary dogs and their ordinary humans can participate in Citizen Science, advancing our understanding of this oldest human coevolution.
Stone tools unearthed at a site in Kenya predate any identified human ancestors -- previously thought to be the first makers of stone tools -- by hundreds of thousands of years. These finds "will force us [to rethink] what makes us humans ... Increasing knowledge of our remote past is casting doubts on previous certainties and is showing that the process of becoming what we are now is far more gradual than what we previously thought."
Scientists estimate that the first eukaryotes evolved about 2 billion years ago, in one of the greatest transitions in the history of life. But there is little evidence of this momentous event, no missing link that helps researchers trace the evolution of life from simple microbes to eukaryotes. On Wednesday, a team of scientists announced the discovery of just such a transitional form.
Experimental archaeology involves moderns crafting Stone Age tools by chipping away at rocks. One reason is to get at the question of what role toolmaking may have played in brain evolution, given the demands this task places on both mental faculties and motor skills.
