Understanding the coevolving web of life as a network

Wed, 18 Oct 2017 13:32:22 EDT ~ Coevolution, which occurs when species interact and adapt to each other, is often studied in the context of pair-wise interactions between mutually beneficial symbiotic partners. But many species have mutualistic interactions with multiple partners, leading to complex networks of interacting species. Find out more...

Fanged kangaroo research could shed light on extinction

Mon, 16 Oct 2017 09:27:19 EDT ~ Fanged kangaroos -- an extinct family of small fanged Australian kangaroos -- might have survived at least five million years longer than previously thought. A new study has found the species might have competed for resources with ancestors of modern kangaroos. Find out more...

Paleogenomic analysis sheds light on Easter Island mysteries

Thu, 12 Oct 2017 12:30:46 EDT ~ New paleogenomic research appears to rule out the likelihood that inhabitants of Easter Island intermixed with South Americans prior to the arrival of Europeans on the island in 1722. Find out more...

Last common ancestor of humans and apes weighed about five kilograms

Thu, 12 Oct 2017 09:09:57 EDT ~ New research suggests that the last common ancestor of apes -- including great apes and humans -- was much smaller than previously thought, about the size of a gibbon. The findings, published today in the journal Nature Communications, are fundamental to understanding the evolution of the human family tree. Find out more...

Mass extinctions led to low species diversity, dinosaur rule

Tue, 10 Oct 2017 12:40:59 EDT ~ Two of Earth's five mass extinction events -- times when more than half of the world's species died -- resulted in the survival of a low number of so-called 'weedy' species that spread their sameness across the world as the Earth recovered from these dramatic upheavals. The findings could shed light on modern high extinction rates and how biological communities may change in the future. Find out more...

Evolutionary stepping stone to beet-red beets discovered

Tue, 10 Oct 2017 10:56:54 EDT ~ Scientists describe an ancient loosening up of a key biochemical pathway that set the stage for the ancestors of beets to develop their characteristic red pigment. Find out more...

Liverwort genes and land plant evolution

Thu, 05 Oct 2017 12:11:44 EDT ~ The common liverwort is a living link to the transition from marine algae to land plants. Biologists have analyzed the genome sequence of the common liverwort (Marchantia polymorpha) to identify genes and gene families that were deemed crucial to plant evolution and have been conserved over millions of years and across plant lineages.

Meet Madagascar's oldest animal lineage, a whirligig beetle with 206-million-year-old origins

Wed, 04 Oct 2017 14:01:25 EDT ~ A new study suggests the Malagasy striped whirligig beetle Heterogyrus milloti boasts a genetic pedigree stretching back to the late Triassic period. Find out more...

Monstrous crocodile fossil points to early rise of ancient reptiles

Mon, 02 Oct 2017 20:22:55 EDT ~ A newly identified prehistoric marine predator has shed light on the origins of the distant relatives of modern crocodiles. Find out more...

Did life on Earth start due to meteorites splashing into warm little ponds?

Mon, 02 Oct 2017 16:12:48 EDT ~ Life on Earth began somewhere between 3.7 and 4.5 billion years ago, after meteorites splashed down and leached essential elements into warm little ponds, say scientists. Their calculations suggest that wet and dry cycles bonded basic molecular building blocks in the ponds' nutrient-rich broth into self-replicating RNA molecules that constituted the first genetic code for life on the planet.
