In the 1800s, critics of evolution insisted there had to be fossil evidence for everything, which neglected the idea that fossilization is already difficult, finding the fossil is even more difficult, and something like an eye will not fossilize at all.

But detractors who insisted they would not accept evolution until they found a "missing link" between modern humans and ancestral primates would be moving the goalposts once again, because a fossil of an ancient hominin individual from Siberia had a Neanderthal mother and a Denisovan father. 

Next month, a Microsoft developer, a classical pianist, and a philanthropist for kids' health will compete in the Miss America pageant. And they are all the same person: Allison Farris.

Farris creates and codes apps for Microsoft as a career but next month she is poised to do something with a different kind of elegance. She will represent Washington, D.C. at the Miss America competition on Sept 9, 2018 in Atlantic City, New Jersey, which will be televised on ABC.

A technique used to produce stone tools that were first found 500,000 years ago is likely to have needed a modern human-like hand, according to new research.

The technique is called 'platform preparation' - preparing a striking area on a tool to remove specific stone flakes and shape the tool into a pre-conceived design - and without the ability to perform highly forceful precision grips, our ancestors would not have been able to produce advanced types of stone tool like spear points. 

Platform preparation is essential for making many different types of advanced prehistoric stone tool, with the earliest known occurrence observed at the 500,000-year-old site of Boxgrove in West Sussex, UK.

Does your base personality change over time? Psychologists are conflicted over that, but Galileo once claimed the Moon did not impact the tides, so without a science foundation, or with poor data gathering, anything is possible. 

And we get both in surveys, which is why a new paper by social psychologists does little to advance psychological science - it declares personality is somewhat hard-wired and somewhat shaped by environment. Which everyone knew 4,000 years ago.

Some exoplanets with masses two to four times the size of Earth can be explained by large amounts of water - and they may be more common than previously thought, say researchers.

The 1992 discovery of exoplanets orbiting other stars has sparked interest in understanding the composition of these planets to determine, among other goals, whether they are suitable for the development of life. Now a new evaluation of data from the exoplanet-hunting Kepler Space Telescope and the Gaia mission indicates that many of the known planets may contain as much as 50% water. This is much more than the Earth's 0.02% (by weight) water content.

A mummy dating from 3700-3500 B.C. housed in the Egyptian Museum in Turin since 1901 has never undergone any conservation treatments - and that provided a unique opportunity for some science.

And the results were a surprise. It was assumed the Turin mummy had been naturally mummified by the desiccating action of the hot, dry desert sand but chemical analysis showed that the mummy had undergone an embalming process, with a plant oil, heated conifer resin, an aromatic plant extract and a plant gum/sugar mixed together and used to impregnate the funerary textiles in which the body was wrapped.
