Complete Genomes of All Known Human Rhinoviruses are Published

... isolates. The whole genome sequencing and bioinformatic analyses on the rhinovirus evolution were conducted at JCVI. By constructing a rigorous phylogeny of all complete HRV genomes, the team gained new insight into rhinovirus evolution. They clearly showed that HRV-A and HRV-C evolved from a common ...

Evolution of HIV from African Greek Monkeys

... constructed phylogenies for the four different SIVagm that showed their relationships. "We put together, for the first time, a really solid phylogeny for African green monkeys, which we didn't have before," Worobey said. If the monkeys' ancestor had been infected with an ancient SIV, the SIV ...

The branches of this evolutionary tree can be calibrated with time using the new phylogeny and DNA data: Even though the ancestor of all sea turtles arose over 100 million years ago, the separation between the flatback and green turtles ...

Scientists reveal the lifestyle evolution of wild marine bacteria

Two studies on bee evolution reveal surprises

... examined early bees' structures in combination with bee DNA, producing the largest molecular and morphological study to date on bee family-level phylogeny -- the evolutionary development and diversification of a species. Their goal was to examine the early evolutionary pattern of bees and how their ...

Sociality of sweat bees evolved simultaneously during climate change

... The DNA sequencing sheds light on how divergent the various species are from each other, and the fossils allow the researchers to represent the phylogeny in terms of a timeline in millions of years. In 2002 and 2004, Danforth showed that the social evolution of the various species of halictid bees ...

The evolution of food plants: Genetic control of grass flower architecture

Maize in particular is an excellent model system for ...

Ancient anthropoid origins discovered in Africa

If down the road we find out that our phylogeny was wrong, Biretia could end up being very significant for our understanding of the origin of anthropoid activity patterns." According to Simons, ...
