Wolf-Coyote-Dog hybrids are being found in much of the U.S., but not in the Western U.S.

In order to resolve a debate over the history and origin of various Wolf populations in the U.S., researchers turned to genetic analysis. In recently published research, the scientists used molecular genetic techniques to look at over 48,000 markers throughout the full genome. The study showed a gradient...

Transgenerational Epigenetic Effects Demonstrated in Animals to Occur From a Variety of Pollutants

Prior posts have discussed the interplay between DNA, the various forms of RNA, and proteins regarding gene "expression"; prior posts have also noted the process of methylation of genes [see Wikipedia - Methylation ], which often reflects the interface between life's experiences and genetic...

Bee Explorers Have a Slightly Different Genetic Makeup than the Rest of the Hive

Researchers have found that honey bees who consistently explore new environments for food have different genetic activity in their brains than their less-adventurous hive mates. In a demonstration how nature often uses the same tools in various settings, though sometimes to yield different mechanisms...

Do comb jellies indicate that evolutionary theory needs a serious rethink? Maybe instead they are a door to understanding the evolution of complexity

When viewing evolution over time, scientists generally favor parsimony, that is, lineages radiating from a common ancestor share most of the ancestor's features. This also means that animals at the bottom have simple features, which may grow more complex or which may become more specialized as other...
