Researchers carry out first in-depth genetic analysis of Neanderthal Y chromosome

Researchers carry out first in-depth genetic analysis of Neanderthal Y chromosome

A research paper published in the American Journal of Human Genetics has unveiled new facts about the relationship between Neanderthals and modern humans and genetic factors that have kept two lineages separate. Earlier research has indicated that modern humans and Neanderthals may have interbred at different times and at different regions.

In the study, researchers have completed the first in-depth genetic analysis of a Neanderthal Y chromosome. The Y chromosome was the main factor that was yet to be assessed from the Neanderthal genome.

Incompatibilities in DNA of Neanderthals and modern humans probably limited impact of interbreeding between them

PENDING-Incompatibilities in DNA of Neanderthals and modern humans probably limited impact of interbreeding between them

This might be the case that incompatibilities in the DNA of Neanderthals and modern humans restricted the impact of interbreeding between these two groups. Now, it is commonly known that a number of modern humans have 4% Neanderthal DNA.

However, a latest analysis of the Neanderthal Y chromosome, which is the genes’ package passed down from fathers to sons, has demonstrated that it is absent in modern populations.

An ancient arthropod carried its baby in a trail similar to kite

An ancient arthropod carried its baby in a trail similar to kite

Scientists have realized a unique practice performed by an ancient creature through its fossils discovered embedded in volcanic deposits in Herefordshire, England. The 430-million-year-old arthropod is somewhat like lobsters and centipedes. The creature used trail made of egg pouches tethered with threads to its baby in order to keep track of its juvenile. This all gave a kite-like effect.

Satellite Imagery hints at Second Viking site in North America

Till date, archaeological site L’Anse aux Meadows is considered as the only Viking site in the Western Hemisphere. Now, archaeologists have discovered another Viking site with the help of satellite imagery. They believe the discovery may unravel more about the history of Vikings.

As per historians, Vikings traveled long distance to enter North America about a thousand years ago. Discovery of the new site in North America may allow researchers to rewrite understandings about Vikings, who are famous for their fearsome conquests.

Scientists reconstruct colors of an ancient snake while it was alive

Scientists reconstruct colors of an ancient snake while it was alive

Using a sophisticated scanning technology, scientists have found what might have been the colors of the skin of an ancient snake, discovered in a colorless fossil. Preserved as a fossil, the 10-million-year-old snake doesn’t have a head. It would have been green colored along with black or brown blotches, and pale on inside.

The study, which appeared on March 31 in the journal Current Biology, reported that the description is similar to some of the present day snakes that belong to the same family.

Spider-look-alike dating back to 305 million years ago providing vital information about arachnid evolution

Spider-look-alike dating back to 305 million years ago providing vital information about arachnid evolution

Discovery of a fossil being dubbed by some as ‘the almost spider’ will certainly help scientists to understand the evolution of modern arachnids. Dating back to 305 million years ago, the fossil is of an ancient arachnid that was found in iron carbonate.

The discovery has been detailed in the Proceedings of the Royal Society B. The species known as idmonarachne brasieri has all the main features of a spider. But it does not have the spinnerets that made spiders so popular. Spinnerets allow spiders to weave and turn their silk into webs.

Lengthy text on slab may unveil name of God or Goddess to whom Etruscans worshipped

Lengthy text on slab may unveil name of God or Goddess to whom Etruscans worshipped

A slab buried for more than 2,500 years is having rich details about Etruscan worship of a God or Goddess. Archeologists in Italy have discovered the inscribed slab from an Etruscan temple. The lengthy text inscribed in sandstone slab will provide a wealth of new information about the lost culture of the Etruscans.

Newly discovered Alaskan butterfly could shed light on Arctic’s geological history

Newly discovered Alaskan butterfly could shed light on Arctic’s geological history

According to researchers, a newly discovered butterfly species from Alaska may shed some more light on the pace of climate change. A study appeared last week in the Journal of Research on the Lepidoptera suggested that the Tanana Arctic, or Oeneis tanana, has probably evolved from an uncommon hybrid when two butterflies species mated prior to the last ice age.

Researchers Claim to Have Solved Prehistoric puzzle Surrounding Tully monster

Researchers Claim to Have Solved Prehistoric puzzle Surrounding Tully monster

Fossil hunters digging the soil near a creek in north-central Illinois have come across a remarkable discovery — Tully monster. They have found the preserved remnants of a prehistoric creature, which appears to be having a long, arm-like appendage extending from below with a pincer-like mouth and its wide-set eyes pointed towards stalks.

Scott Lidgard, a paleontologist at Chicago’s Field Museum, said the Tully monster, which is Illinois’ official state fossil, beyond doubt was “very, very bizarre”.

New dinosaur fossil uncovers how T. rex topped food chain

New dinosaur fossil uncovers how T. rex topped food chain

Tyrannosaurus rex, a 40 feet long behemoth killer dinosaur, topped the food chain over 70 million years ago. However a new study has revealed that in the state, the size of tyrannosaurs species was small, comparable to humans. The evolution of species into a much bigger size has surprised paleontologists.

Paleontologists unearthed a fossil in Uzbekistan, which revealed missing link in the evolution of T. rex. The fossil belongs to a tyrannosaur, which had characteristics like a T. rex, but it wasn’t 40 feet long.
