African apes adapted to living on the ground, a finding that indicates human evolved from an ancestor not limited to tree or other elevated habitats. The analysis adds a new chapter to evolution, shedding additional light on what preceded human bipedalism.
An associate director of Mississippi State’s Northern Gulf Institute is receiving international attention for his eye-opening study on the impact exotic species have on native marine communities.
A hybrid bird species on the Galapagos Islands could help scientists find a way to stop an invasive fly which is killing off the hatchlings of famous Darwin’s finches at an alarming rate, according to new research. 10 related species of the iconic Darwin’s finches are being threatened by the invasive fly Philornis downsi from South America, which lays its eggs into birds’ nests where the predators then hatch and devour defenceless chicks before the parents can react.
You may think human sex is bizarre enough. But elsewhere in the animal kingdom, features like competition between sperm and semen that influences behavior conspire to make it even weirder. A special issue of the journal Molecular & Cellular Proteomics highlights recent discoveries in the reproductive biology of species from insects to crocodiles. Here are some highlights.
A new study reveals the surprising way that family quarrels in seeds drive rapid evolution. Researchers in Arts & Sciences discovered that conflict over the amount of resources an offspring receives from its parent seems to play a special role in the development of certain seed tissues. The study is published the week of April 22 in the Proceedings of the National Academy of Sciences.
Paleontologists at Ohio University have discovered a new species of meat-eating mammal larger than any big cat stalking the world today. Larger than a polar bear,
A new study into one of the world’s oldest types of fish, Coelacanth, provides fresh insights into the development of the skull and brain of vertebrates and the evolution of lobe-finned fishes and land animals, as published in Nature.
As you bite into a chocolate bunny or egg this weekend, consider this: rabbits often eat their own young, and hens their own eggs.
The scientific community has long held an understanding about the effect of temperature on sperm production in mammals, but this new study sheds light on how spermatogenesis in insects is hampered at extreme temperatures.
University of Maryland researchers analyzed an evolutionary tree reconstructed from the DNA of a majority of known bat species and found four bat lineages that exhibit extreme longevity. They also identified, for the first time, two life history features that predict extended life spans in bats.
The evolution of aquatic creatures to start living on land made them into more attentive parents, says new research on frogs led by the Milner Centre for Evolution at the University of Bath.
Stony Brook University's Liliana Dávalos, PhD, is studying the phenomenal capabilities of the shrew, which shrinks up to 20 percent during winter months without hibernating. The research may shed light on the processes of neurological degeneration and regeneration in mammals.
Biodiversity hotspot Madagascar is one of the world's biggest islands, and home to some of its biggest insects. Now German scientists have discovered two new species of giant stick insect, living only in the dry forests of Madagascar's northernmost tip.
Birds-of-paradise are a group of songbird species, and are known for their magnificent male plumage and bewildering sexual display. Now, an international collaborative work involving Dept. of Molecular Evolution and Development of University of Vienna, Zhejiang University of China, and Swedish Museum of Natural History analyzed all together 11 songbird species genomes, including those of five bird-of-paradise species, and reconstructed the evolutionary history of their sex chromosomes.

Some diseases which are fatal in one species can cause only mild discomfort in another--but it's hard for scientists to predict how lethal a disease will be if it leaps across species.
The neurobiology of turtle ants differs significantly according to their specialized role within the colony, according to a study published March 27, 2019 in the open-access journal PLOS ONE by Darcy Greer Gordon from Boston University, USA, and colleagues.
A Costa-Rican lizard species may have evolved scuba-diving qualities allowing it to stay underwater for 16 minutes, according to faculty at Binghamton University, State University of New York.
Evolutionary biologists at McMaster University who study the social lives and behaviour of colony spiders—some of which are docile, others aggressive— have found that the success of their cooperative societies depend on their neighbours.
The ~125 million-year-old Early Cretaceous fossil beds of Los Hoyas, Spain have long been known for producing thousands of petrified fish and reptiles (Fig. 1). However, one special fossil stands unique and is one of the rarest of fossils -- a nearly complete skeleton of a hatchling bird.
