It is well-known that living fossils exhibit stasis over geologically long time scales. Examples are the panda and ginkgo. Now, two tiny beetles trapped in 99-million-year-old amber may join this group.
Most aspects of dental development for a juvenile Homo specimen from the Pleistocene fall within the modern human range, according to research by a group of Chinese and international scientists. The study was recently published in Science Advances.
In the Jan. 17, 2019, online edition of PLOS One, Utah State University and USDA researchers report findings about pollinator biodiversity in California's Pinnacles National Park derived from data collected from three separate surveys spanning 17 years. Their results documented 450 species of wild, native bees at Pinnacles, including 48 new to the area since 2002, and 95 detected at the site in the 1990s, but now missing.
The reintroduction program for the green turtle in the Cayman Islands is crucial in order to recover this species, which are threatened by the effects of human overexploitation, according to a study published in the journal Molecular Ecology
Females love males with big dorsal fins, but the appendages first evolved for males to fight other males
"When the chicks first go in the water, they are very awkward and unsure of themselves," says Sara Labrousse, a postdoctoral investigator at WHOI and lead author of the paper. "They are not the fast and graceful swimmers their parents are."
Scientists at the University of Southampton have developed maps of chemicals found in jellyfish which could offer a new tool for the protection of British waters and fisheries.
A new WCS-led study published in the journal Biological Conservation says the future of tigers in Asia is linked the path of demographic transition--for humans. The study marks the first-of-its-kind analysis that overlays human population scenarios with the fate of these endangered big cats.
11,500 years ago in what is now northeast Jordan, people began to live alongside dogs and may also have used them for hunting, a new study from the University of Copenhagen shows. The archaeologists suggest that the introduction of dogs as hunting aids may explain the dramatic increase of hares and other small prey in the archaeological remains at the site.
What does the blue whale have in common with the Bengal tiger and the green turtle? They share the risk of extinction and are classified as endangered species. There are multiple reasons for species to die out, and climate changes is among the main reasons.
Honey bee colonies around the world are at risk from a variety of threats, including pesticides, diseases, poor nutrition and habitat loss. Recent research suggests that one threat stands well above the others: a parasitic mite, Varroa destructor, which specializes in attacking honey bees.
Study: Animal populations are decreasing due to their high-risk food-finding strategies
Primates of the Caribbean: Ancient DNA reveals history of mystery monkey
Alien-like long, ridged organisms are now classified as the oldest known animals on the planet. The Dickinsonia, approximately 558 million years old, puzzled scientists for decades, but fat molecules finally solve the mystery.
