Apr. 21, 2016 — In comparison to their relatives on the mainland, the Channel Island foxes living on six of California's Channel Islands are dwarves, at two-thirds the size. The island foxes most likely evolved ... read more

Apr. 21, 2016 — New research examining the DNA of North American mammoths challenges the way we categorize a species. Several species of mammoth are thought to have roamed across the North American continent. The ... read more

Apr. 21, 2016 — In rare instances, DNA is known to have jumped from one species to another. If a parasite's DNA jumps to its host's genome, it could leave evidence of that parasitic interaction that could ... read more

Apr. 21, 2016 — Our gut microbes are key to our health, but they may also shape our evolution, according to a new hypothesis. Expanding on the concept of the hologenome -- the host genome together with the genomes ... read more

Apr. 20, 2016 — The 13-million-year-old fossils of an extinct crocodylian, named 'the storyteller,' suggest that South American and Indian species evolved separately to acquire protruding, ... read more

Ancient DNA Reveals Evolution of Giant Bears in the Americas

Apr. 20, 2016 — Researchers are shedding new light on the evolution of what are believed to be the largest bears that ever walked the ... read more

Apr. 19, 2016 — Latest analysis shows that human limbs share a genetic programme with the gills of cartilaginous fishes such as sharks and skates, providing evidence to support a century-old theory on the origin of ... read more

Apr. 18, 2016 — A new study presents evidence that the rise of atmospheric oxygenation did indeed occur 2.4-2.1 billion years ago. It also shows that biological usage of copper became prominent after the so called ... read more

Apr. 18, 2016 — Dinosaurs were already in an evolutionary decline tens of millions of years before the meteorite impact that finally finished them off, new research has ... read more

Scientists Discover C4 Photosynthesis Boosts Growth by Altering Size, Structure of Plant Leaves, Roots

Apr. 18, 2016 — Plants using C4 photosynthesis grow 20-100 percent quicker than more common C3 plants by altering the shape, size and structure of their leaves and roots, according to a new ... read more

Scorpion Toxin Insights May Lead to a New Class of Insecticides

Apr. 14, 2016 — The molecular clues driving the effectiveness of scorpion toxins has now been identified by scientists. This finding could lead to the promising new candidates for insecticides, and fine-tuning these ... read more

Genetic Diversity Helps to Limit Infectious Disease

Apr. 13, 2016 — The idea that host diversity can limit disease outbreaks is not new. For example, crop monocultures in agriculture -- which lack genetic diversity -- can suffer severe disease outbreaks that sweep ... read more
