Nov. 21, 2015 — A new study shows that larger eye size is the source of a sizable reproductive advantage for a tiny freshwater crustacean, Daphnia obtusa. The research provides hard data for eye microevolution that, ... read more

Nov. 20, 2015 — Deleting the genes for sugar-adding enzymes from the flowering mustard plant Arabidopsis and the moss Physcomitrella resulted in similar defects in both species, which are widely separated in ... read more

Nov. 19, 2015 — In a recently published paper, Indiana University biologists have calculated the lifetime energy requirements of multiple types of cells, as well as the energy required to replicate and express the ... read more

Nov. 18, 2015 — Scientists have analyzed the genomes of two acorn worm species and found that approximately two-thirds of human genes have counterparts in the ancestors of these marine animals. These ancient genes, ... read more

Nov. 18, 2015 — In the animal world, if several males mate with the same female, their sperm compete to fertilize her limited supply of eggs. Longer sperm often seem to have a competitive advantage. However, a study ... read more

Nov. 18, 2015 — Researchers have discovered several new species of marine fungi inhabiting previously undescribed branches of the tree of life. Little is known about the fungi flourishing in the world's oceans ... read more

Nov. 17, 2015 — Using some ancient DNA detective work, a new study has linked the culprit behind the 19th-century Irish potato famine, which was transported to Europe in the 1840s, to a fungus-like organism that ... read more

Nov. 16, 2015 — Redundancy is common in nature, for example many human genes exist in several copies. However, excessive redundancy can interfere with efficiency. Therefore, each whole genome duplication event is ... read more

Nov. 16, 2015 — Researchers have revealed how a jellyfish -- those commonplace sea pests with stinging tentacles -- have evolved over time into 'really weird' microscopic organisms, made of only a few ... read more

Nov. 16, 2015 — A new analysis of the jaw of one of the earliest known proto-mammals sheds light on efforts to accurately date the period when mammals first evolved and clarifies the mammalian family tree. The study ... read more

Nov. 16, 2015 — New research has revised the horned praying mantis group and traced the evolution of its distinctive camouflage features, suggesting that disruptive camouflage evolved twice within the ... read more

Nov. 16, 2015 — Whether you’re territorial, a girlfriend stealer, or a cross dresser, when it comes to finding a partner, scientists have discovered that for some birds it’s all in the ... read more

'Supergene' Underlies Genetic Differences, Sexual Behavior in Male Ruff

Nov. 16, 2015 — The ruff is a Eurasian shorebird that has a spectacular lekking behavior where highly ornamented males compete for females. Now two groups report that males with alternative reproductive strategies ... read more

Nov. 13, 2015 — In the 19th century, Darwin's most vocal scientific advocate was Thomas Henry Huxley, who is also remembered as a pioneer of the hypotheses that birds are living dinosaurs. He noticed several ... read more

Nov. 12, 2015 — A previously undiscovered dinosaur species showcases an evolutionary transition from an earlier duckbilled species to that group's descendants. The findings highlight how the new species of ... read more

Digging Deeper Into DNA: Efficient Method to Sequence Chloroplast Genomes

Nov. 11, 2015 — A new bioinformatics strategy provides a time- and cost-efficient method to assemble a chloroplast genome using whole-genome sequencing. In a new study, researchers extracted whole-genome sequence ... read more

Nov. 11, 2015 — They might be looking quite identical, but each of the populations of two owl species, living in the opposite hemispheres, might actually turn out to be yet another kind. This suggestion has been ... read more

Nov. 11, 2015 — Evolutionary biologists have discovered that the oldest known nectar-drinking bat fossil, Palynephyllum antimaster, was probably ... read more

Nov. 10, 2015 — Cacao trees evolved around 10 million years ago, earlier than previously believed, new research shows. Considerable genetic variation might remain to be discovered among wild cacao populations, which ... read more

Nov. 9, 2015 — Scientists have revealed new discoveries about how animal venom evolves. The research points to a 'two-speed' evolution of animal venom, showing for the first time the significant roles ... read more
