Did Inbreeding Drive Woolly Mammoths To Extinction?
2014-03-26 09:19:04

Lawrence LeBlond for redOrbit.com - Your Universe Online Much of what we know about the Mammoth may be challenged after new research from a Dutch team has found evidence that the massive mammal may have driven itself to extinction due to inbreeding. The evidence comes from an unusual feature found in some mammoth fossils taken from the North Sea. This unusual feature suggested to the research team, led by paleontologist Jelle Ruemer of the Natural History Museum Rotterdam, the...

Study Reveals First Ever Images Of Early Tetrapod Backbone And How It Helped In Land Evolution

[Watch Video: 3D X-Ray Images Of Early Tetrapod Backbone] Lawrence LeBlond for redOrbit.com - Your Universe Online Using high-energy X-rays and a new data extraction protocol, an international consortium of scientists have for the first time rendered a 3D model of a prehistoric tetrapod backbone. The new reconstruction has shed new light on how the early animals moved once they made it onto land. One of the main creatures studied was a fierce-looking ichthyostega that lived from 374...

Aquatic Eel Fossil Has Human-like Spine Morphology

Surprise discovery contradicts theories about anatomy exclusive to land animals For decades, scientists believed that a spine with multiple segments was an exclusive feature of land-dwelling animals. But the discovery of the same anatomical feature in a 345-million-year-old eel suggests that this complex anatomy arose separately from — and perhaps before — the first species to walk on land. Tarrasius problematicus was an eel-like fish that lived in shallow bodies of water in...

Here's an anatomical packing list for making that historic trip from water to land circa 370 million years ago: Lungs? Check. Legs? Check. Patches of highly vascular bone in the skin? In a new paper, scientists propose why many of the earliest four-legged creatures that dared breathe on land carried bony skin features. The "dermal bones" within the skin, especially the bones covering the skull roof and forming part of the shoulder girdle, had a highly complex surface of ridges and furrows...

From blue whales to earthworms, a common mechanism gives shape to living beings Why don't our arms grow from the middle of our bodies? The question isn't as trivial as it appears. Vertebrae, limbs, ribs, tailbone ... in only two days, all these elements take their place in the embryo, in the right spot and with the precision of a Swiss watch. Intrigued by the extraordinary reliability of this mechanism, biologists have long wondered how it works. Now, researchers at EPFL (Ecole...

As a rule all mammals have the same number of vertebrae in their necks regardless of whether they are a giraffe, a mouse, or a human. But both sloths and manatees are exceptions to this rule having abnormal numbers of cervical vertebrae. New research published in BioMed Central's open access journal EvoDevo shows how such different species have evolved their unusual necks. Birds, reptiles and amphibians have varying number of vertebrae in their necks, swans have 22-25, but mammals, regardless...

New research by scientists at the University of Cambridge in England gives insight into how sloths, one of the few mammals with more than seven neck vertebrae, evolved their uniquely long necks. The mystery of how the three-toed sloth came to have as many as 10 neck vertebrae has long puzzled scientists, given that most of the 5,000 mammal species have exactly seven vertebrae in their necks. Other animals, such as birds and lizards, vary greatly in the number of vertebrae in their...

Instituto Gulbenkian de Ciencia researchers reveal process of making ribs Like all vertebrates, snakes, mice and humans have in common a skeleton made of segments, the vertebrae. But a snake has between 200-400 ribs extending from all vertebrae, from the neck to the tail-end, whereas mice have only 13 pairs of ribs, and humans have 12 pairs, in both cases making up the ribcage. In the latest issue of Developmental Cell(*), researchers from the Instituto Gulbenkian de...

A 51-year-old actor seriously hurt before a performance of the Broadway musical, "The Little Mermaid," reportedly is suing Disney, his employer at the time. Adrian Bailey said in a lawsuit filed Thursday that he tumbled through a trap door more than 30 feet to the stage in May, fracturing his back, wrists, hips, pelvis, sternum, ribs and foot, the New York Post reported. The ensemble player is seeking unspecified money damages. "My life has been changed forever. It will never be the...

Stroud jockey Jason Maguire has sustained multiple injuries in a fall during a race. He fractured his sternum, broke two ribs and punctured a lung in the incident at Market Rasen on Sunday. Maguire, who was taken to Lincoln Hospital, said it was unclear how long he would be out of action. "I haven't thought about what comes next, but hopefully some time this week I will be transferred to a hospital near home where I can talk to my doctor and get a proper verdict," he said.
