 | Like any species that aspires to rule the world, the honey bee, Apis mellifera, invades new territories in repeated assaults. A new study demonstrates that when these honey bees arrive in a place that has already been invaded, the newcomers benefit from the genetic endowment of their predecessors. ...> Full Article |
Researchers have created the highest resolution map of human genetic diversity to date, providing insight into how groups of people throughout the world are related and adding weight to previous theories that humans originated from Africa.

 | Scientists have produced the largest and most detailed worldwide study of human genetic variation, a treasure trove offering new insights into early migrations out of Africa and across the globe. ...> Full Article |
Scientists who have studied the genome of the virus that caused severe acute respiratory syndrome (SARS) say their comparisons to related viruses offer new evidence that the virus infecting humans originated in bats.

 | The newly sequenced genome of a one-celled, planktonic marine organism, reported today (Thursday, Feb. 14) in the journal Nature, is already telling scientists about the evolutionary changes that accompanied the jump from one-celled life forms to multicellular animals like ourselves. ...> Full Article |
The human journey from Asia to the New World was interrupted by a 20,000-year layover in Beringia, a once-habitable region that today lies submerged under the icy waters of the Bering Strait.

 | Parts of feline immunodeficiency virus (FIV) isolated from wild lions have undergone substantial genetic recombination, says new research. The sequencing of the two full FIV genomes of different lion subtypes shows the importance of whole-genome analysis in understanding complex genetic events. These findings will be relevant to big cat conservation and developing more effective animal models for HIV. ...> Full Article |
Did modern birds originate around the time of the dinosaurs' demise, or have they been around far longer?

 | More than 99 percent of all modern potato varieties planted today are the direct descendents of varieties that once grew in the lowlands of south-central Chile. How Chilean germplasm came to dominate the modern potato-which spread worldwide from Europe-has been the subject of a long, contentious debate among scientists. ...> Full Article |
 | DNA of the common Black Rat has shed light on the ancient spread of rats, people and diseases around the globe. Studying the mitochondrial DNA of 165 Black Rat specimens from 32 countries around the world, an international team of scientists has identified six distinct lineages in the Black Rat's family tree, each originating from a different part of Asia. ...> Full Article |
