Parents have been doting over their offspring for a very, very long time, it seems. A South African fossil suggests pelycosaurs -- intermediates between reptiles and mammals that lived in the Permian Period before the rise of dinosaurs -- may have been caring parents 260 million years ago, scientists said on Wednesday.

A new DNA analysis indicates that the parasites  accompanied their human hosts in the original peopling of the Americas, probably as early as 15,000 years ago.

Scientists comparing the DNA sequence of brain genes in several species of primate have found that the genes that specify the architecture of the human brain seem to have started evolving faster some 20 million years ago.

Researchers have identified more genetic mutations that appear to be linked with cot death.

It has long been clear that chronic stress wreaks havoc on our health. Scientists have now found molecular signs of this harm. In a study of mothers of chronically ill children, the cells

Scientists have discovered genetic information that helps explain how monarch butterflies find their way from Canada to winter nesting grounds in the mountains of Mexico.

Researchers studying the causes of facial clefts have identified a handful of new genetic mutations linked to these birth defects in a step that might help lead to a test to predict a family's risk.

The ability of early human ancestors to run long distances may have influenced the transition to today's body form, researchers report.

A married couple who sailed to America from England around 1630 are the reason why thousands of people in the United States are at higher risk of a hereditary form of colon cancer, researchers said on Wednesday.

Science & environment: Humans are evolving faster than ever, says a new study tracking changes in our genes. But some scientists believe we may be going backwards

A group of researchers has re-created with remarkable accuracy part of the genome of the common ancestor of all placental mammals, a small shrew-like creature that prowled the forests of what is now Asia more than 80 million years ago.

The old adage that being overweight &quot;is in the genes&quot; may be true, at least partially, for some, say researchers. A team from the University of Marberg in Germany found mutations in the MC4R gene had a &quot;major&quot; impact on people&#39;s body mass index.

Scientists mapping genetics of two of the nation's leading cancers have found almost 200 mutated genes in breast and colorectal tumors, many of them never before suspected of helping cancer form and spread.

Australian scientists have found a new species of hobbit-sized humans who lived about 18,000 years ago on an Indonesian island. The discovery adds another piece to the complex puzzle of human evolution.

Now a team of researchers has found that severe emotional distress - like that caused by divorce, the loss of a job, or caring for an ill child or parent - may speed up the aging of the body&#39;s cells at the genetic level.
