A recent study reveals that inbreeding among Neanderthals have resulted to a harmful gene mutation, which was then passed on to modern humans, making them 40 percent less likely to reproduce.
A new study shows that inbreeding might negatively affect the length of telomeres leading to a shorter lifespan.
It turns out that wolves, jackals and domestic dogs have different howling dialects or "vocal fingerprints." Researchers say this may help them better identify species, and therefore their conservation status.
National Park Service biologists recently discovered two mountain lion kittens in the Santa Monica Mountains in California. The pair's mother is thought to be a well-tracked mountain lion designated as P-19, but DNA testing is underway to confirm who their father is. Nonetheless, researchers say this successful birth highlights the habitat quality of the Santa Monica Mountains.
Cheetahs migrated to Africa from North America 100,000 years ago during the last Ice Age. Following their "big move," populations dwindled and incestuous breeding increased. This troubled linage has had a lasting impact on modern Cheetahs, many of which have difficulty reproducing due to a gene mutation that affects sperm development.
For many species, including humans, sex is determined by sex chromosomes. However, this is not the case for ants, wasps and bees. A recent study sheds light on the evolution of sex determination in ants and how inbreeding can lead to sterile males.
Recently, a small herd of bison were released in Colorado. This suggests there is hope for the large buffalo that have been struggling to revive themselves ever since populations plummeted in the 1800s.
Conservationists recently created a new nature reserve known as the Geometric Tortoise Preserve to house the largest and last viable population of geometric tortoises.
A study on a breed of farmbirds known as Plymouth Rock chickens suggests evolutionary differences can be observed on a much shorter time scale than previously thought.
New research from the University College Dublin shows Cows were domesticated in stages and far more selectively than previous research indicated. DNA analysis indicates ancient British farmers restocked their domesticated herds with still-wild ox specimens called aurochs that grazed throughout areas of Europe, Asia and North Africa.
Wild and domesticated horses began evolving differently from one another some 45,000 years ago, but a recent study has revealed their genetics ties and is providing a greater understanding of both past and present populations.
Inbreeding among Saltmarsh sparrows and Nelson's sparrows is creating a hybrid zone that is difficult for researchers to identify--and threatening the species with extinction.
More have made it! Nearly three years after the famous "Hollywood mountain lion" crossed the Southland freeways looking for a new home, two more have braved and successfully accomplished the same feat.
There are only three wolves left in Michigan's Isle Royale National Park, making scientists concerned for the survival of this lone group, new research finds.
Mountain gorillas are currently suffering from a serious inbreeding problem, and while scientists everywhere worry that this will lead them down the path to extinction, one new genetic study says that it might in fact be their salvation.
