Tens of thousands of years ago, our species (Homo sapiens) mixed and bred with other prehistoric humans.
Hundreds of Neanderthal fossils give us a good idea of their appearance, life and relationships, but little is known about Denisovan, so they still don’t have an official Scientific name.
Evidence of their existence emerged with faint traces, mapped by DNA markers lurking in our own genetic makeup, and confirmed by several fossil fragments.
But the 146,000-year-old skull, drowned from a Chinese well this week in 2018, may be an important missing piece of this inexplicable evolutionary puzzle.
The almost perfect skull was not consistent with previously known prehistoric humans.
But two new studies, which researchers say is one of the biggest paleontological papers of the year, detail how scientists can extract genetic material from fossils and unravel this biological mystery.
DNA samples taken from “Dragon Man” as the specimen was called revealed that he was actually associated with the Denisovans.
This discovery is monumental and helps us to paint a richer picture of an era when our own species coexisted with other prehistoric humans.
Astronomers have long been tackling the confusion of “dark matter,” but many mysteries also surround normal matter.
Protons and neutron-based atoms that we know well are called baric matter. And this material is scattered among galaxies like intergalactic mist, making it extremely difficult to measure.
Probably that’s up to now.
A new study explains how scientists can observe baric material using fast radio burst flashing.
Researchers capture elusive squid with camera
In a rare encounter, scientists filmed the first footage of an elusive three-foot squid living in its deep-sea habitat.
Fruits, flowers, birds and musical instruments adorned the walls of the gorgeous villa. This is part of a drilling team called “Beverly Hills” in Rome, England, before the building was destroyed about 1,800 years ago.
The frescoes were strugglingly pieced together by the archaeological experts at the London Museum. Han Li, senior building materials specialist at Mola, described the effort as an “once in a lifetime” opportunity.
The Romans invaded modern Britain in 43 AD and founded the predecessor of modern London, the Rondinium. The occupation lasted almost 400 years.
Under the life-affirming glow of the sun, methane is a dangerous gas to avoid.
Methane, a thermally blocked chemical pollutant in the Earth’s atmosphere, exacerbates the climate crisis. However, within the planet’s deep recesses (thousands of feet below sea level off the west coast of the US), gas can be converted into a nutritious diet.
At least for spiders.
Scientists say they have discovered three previously unknown sea spider species that lived around methane penetration. In these marine habitats where sunlight is not accessible, gases feed through cracks in the seabed and supply bacteria that latch into the spider exoskeleton.
New research shows that bacteria convert carbon-rich methane and oxygen into sugars and fats.
The newly discovered spiders in the Sericosura sea could pass methane-fueled bacteria to hatch as a simple food source, researchers suggest.
