A University of Pennsylvania paleontologist has described a 5.5 million-year-old fossil species of turtle from eastern Tennessee. It represents a new species of the genus Trachemys, commonly known as sliders, which are frequently ...
The tropical rainforests of Central and South America are home to the largest diversity of plants on this planet. Nowhere else are there quite so many different plant species in one place. However, the entire region is increasingly ...
Diploid vertebrates have two sets of chromosomes, one from each parent. In contrast, polyploidy, meaning to possess three or more sets of chromosomes, is very rare in animals. To find out how new vertebrate species have evolved, ...
A group of North American Pleistocene horses was previously identified as different species. Now, mitochondrial and partial nuclear genomic studies support the idea that there is only one species, which belongs to a new genus.
We all know viruses cause colds and flu this time of year, but you might be surprised to learn that a virus may have played a key role in the evolution of nearly all life forms on Earth.
Scientists from University College London (UCL) and the Academy of Mathematics and Systems Science, Chinese Academy of Sciences (CAS, AMSS), have reported progress in understanding problems associated with Bayesian model ...
More than 100 researchers have collaborated to classify the world's tropical forests according to their evolutionary history, a process that will help researchers predict the resilience or susceptibility of different forests ...
New research that analyzed more than 270 million years of data on animals shows that mammals and birds - both warm-blooded animals - may have a better chance of evolving and adapting to the Earth's rapidly changing climate ...
Is it possible to predict which nonnative plant species will become invasive weeds and when? According to research featured in the journal Invasive Plant Science and Management, the answer is "hopefully yes." And those predictions ...
Researchers have conducted chemical analysis of biomarkers remaining after the decomposition of the genus Beltanelliformis. These organisms populated the Earth in the Ediacaran period (about 575-541 million years ago), and ...
