Fast running restricts evolutionary change of the vertebral column in mammals. PNAS, 2014 DOI: 10.1073/pnas.1401392111 ...

Lumbosacral transitional vertebrae (LTV) manifest as one or several abnormal vertebrae in the lumbosacral spine. The transitional vertebrae bear the characteristics of both lumbar and sacral vertebrae ...

One of the riddles of mammal evolution is explained: the conservation of the number of trunk vertebrae. Dutch and American researchers show that this conservation is due to the role of speed in ...

Other patients had "transitional vertebrae" between the lumbar spine and sacrum. This malformation also affected the rate of L4/L5 versus L5/S1 herniation, depending on the location of the ...

The lumbosacral joint, the connection between the vertebral column and the hips, has to be very flexible in fast running mammals with an agile lifestyle, and any mutations which reduce this ...

HOUGHTON, Mich., April 7 (UPI) -- Scientists say they've found extreme inbreeding of an isolated wolf population at a U.S. island national park has resulted in genetically deformed bones. Michigan ...
