Mona Island caves shed light on dialogue between Europeans and Native Americans

Archaeologists have discovered evidence as to how the first generations of Europeans in the Americas have mingled with indigenous population. Researchers from the British Museum and the University of Leicester have come to know through inscriptions found in the caves of a remote Caribbean island.

The research paper published in Antiquity is based on the finding of a large collection of early colonial inscriptions and commentaries being written by named individuals within a cave system provide an insight into dialogue between Europeans and Native Americans.

Turtles have originally evolved shells for underground burrowing: Study

Turtles have originally evolved shells for underground burrowing: Study

If you think turtles have been using their shells as shields since they have evolved then you are highly mistaken. A new study has unveiled that shells were evolved for a complete different reason. The researchers believe that the shell-like characteristics first evolved in turtle ancestors to burrow underground.

Study’s lead researcher Tyler Lyson, a paleontologist from the Denver Museum of Nature & Science said that in the same way as bird feathers did not initially evolve for flight, the starting of turtle shell was not meant for protection.

Closed-mouth vocalization might be present in some dinosaurs

Closed-mouth vocalization might be present in some dinosaurs

A research paper posted online in the journal Evolution has unveiled that not every dinosaur roared ferociously. As per researchers, there were some dinosaurs that used to mumble or cooed with closed mouths.

In the study, the researchers have closely studied a way using which birds emit sounds known as closed-mouth vocalization. In order to understand when and as to how closed-mouth vocalization evolved, international researchers used a statistical approach.

Remains found in Belgium cave are clear-cut evidence of Neanderthal cannibalism

First evidence of Neanderthal cannibalism in northern Europe has been found by archaeologist while they were excavating the Goyet caves in Belgium. The remains found from the caves have unveiled that the Neanderthals were involved into butchering and used the bones of their peers as tools.

Scientists find evidence of facial tumor after jaw analysis of dwarf dinosaur

For the first time, researchers have discovered a type of non-cancerous facial tumor, found in humans, mammals and some reptiles, in fossil animals. An international team of researchers has found timorous facial swelling in the fossil of the jaw of the dwarf dinosaur Telmatosaurus transsylvanicus in Transylvania.

Ancient insects used to wear camouflage outfits for protection

Humans aren’t alone who attire to hide themselves in forests etc, as some insects also followed the practice. Small bugs cover their bodies with pieces of plant matter, dirt, and even the exoskeletons of other insects to camouflage from predators and hunt for prey.

Archaeologists find Pottery Pieces belonging to Roanoke Colony

Roanoke Colony, established in late 16th century on Roanoke Island, has been a mystery for researchers since its sudden disappearance. Now, a team of archaeologists has discovered remains of the colony, also known as the Lost Colony, which could shed light on it.

Archaeologists at North Carolina's Roanoke Island announced that during a dig in the region, they found two pieces of blue-and-brown pottery. They believe the pottery pieces could be part of an apothecary jar that was used four centuries ago.

Climate change pushed megafauna into extinction: research

Climate change pushed megafauna into extinction: research

Large mammals like sloths, saber-toothed cats, giant bears and mammoths lived in South America and went extinct around 12,000 years ago. Evolutionary biologists and ecologists believe that blame two possible culprits for the disappearance of those gigantic mammals.

One possibility is that those ancient large mammals went extinct because of the peopling of the Americas. Supporters of this theory believe that humans hunted the big animals to extinction.

Evidence from bison fossils helps scientists determine how first people migrated to Americas

Evidence from bison fossils helps scientists determine how first people migrated to Americas

With the help of evidence from bison fossils, scientists have found when an ice-free corridor opened up down the Rocky Mountains in the late Pleistocene. The corridor was considered a probable route through which humans and animals might had have migrated between the far north and the rest of North America, but when and how it was used isn’t known so far.

Combing the radiocarbon dating and DNA analysis, the researchers tracked the bison’s movements into the corridor, indicating that it was completely open by nearly 13,000 years back.
