evolution

DNA analysis gives clues to how the ancient hominin’s population split and how they interacted with modern humans.

A device dubbed the “mother machine” enables real-time observation of mutagenesis in single bacterial cells.  

In an unusual evolutionary twist, local stick spiders have come up with an almost identical repertoire of color morphs in multiple locations.

In audio files from 2005, the future Administrator of the EPA said there’s a lack of “sufficient scientific facts” to back the theory.

Researchers are looking to proteins to explore the biology of ancient organisms, from medieval humans all the way back to dinosaurs.

The male proboscis monkey’s large nose probably evolved in response to female preference and competition between males.

Dampening the immune response to stay up in the air may have helped bats become tolerant to viral infections.

A closer moon and ideal coastal conditions for tide pool formation may have started the evolutionary transition of tetrapods.

Poecilia formosa, an all-female fish species, has a surprisingly robust genome. 

Two studies identify a signaling pathway that contributes to the fish’s sleeplessness.

Over the past seven years, Xiao-Long Lin has characterized nearly 70 new species of nonbiting midges and developed DNA barcodes to aid in future ecological surveys.

Humanity would be nothing without plants. It’s high time we recognize their crucial role in sustaining life on Earth.

Insect wings may have evolved from multiple origins, say researchers.

Scientists study the unusual genome evolution of the bacteria that live within a genus of cicadas. 

Developmental biologists take a close look at how alligator embryos grow. 

Syrian hamsters and thirteen-lined ground squirrels are tolerant of chilly temperatures, thanks to amino acid changes in a cold-responsive ion channel. 

Entomologists have rediscovered a species of moth that was considered lost for 130 years. 

Factors such as humidity and temperature can affect how Rhinolophus clivosus use echolocation. 

Aggressive little marine predators, mantis shrimps possess a mushroom body that appears identical to the one found in insects.

The fossil booty includes some eggs with embryo remains inside, and points to group nests involving long-term parental care.
