Don't stand so close to me: A new view on how species coexist

...ces in their life histories, opened up between the evolving parasitoid wasp species, which are not filled by others. They suggest this may explain the great diversity of wasps seen in nature. "There is a fixed amount of difference necessary," says Dr Bonsall. "This allows evolution to affect patterns of diver...

Research gaining momentum by silencing genes

...ve done this gene by gene, but research is rapidly evolving towards investigating multiple genes in parallel. Of course, new technologies are always needed to make these leaps, and RNAi is one such technology. This new technology makes it possible to prevent the production of a protein with a specifically des...

Researchers redrawing the Tree of Life

... magnolias or buttercups were some of the earliest evolving flowering plants, or the base of the flowering plants tree. Now, Hilu said, a small shrub from New Caledonia called an Amborella forms the base, with water lilies coming directly after that. "This indicates a major shift from a shrub of terrestrial h...

International human genome sequencing consortium describes finished human genome sequence

...roups around the world, this important and rapidly evolving part of our genome is open for scientific exploration," said Robert H. Waterston, M.D., Ph.D., former director of the Genome Sequencing Center at Washington University in St. Louis and now chair of the Department of Genome Sciences at the University ...

Insects implicated in the evolution of new human infectious diseases

...ecoming harmful to people — in other words by evolving into a new type of disease which we haven't seen before. "The species of bacteria may have been around for centuries, but it is just that a new strain evolves that is suddenly able to infect humans as well as other animals. "The picture is further c...

Emory study details dolphin brain evolution for the first time

...etaceans arrived at the same cognitive space while evolving along quite different paths" Marino says. "What the data say to me is that we, as humans, are not that special. Although we are highly encephalized, it's not by much or for that long compared with odontocetes." Marino and her colleagues add that the ...

Humans and dolphins: If brain size is a measure, we're not that different

...etaceans arrived at the same cognitive space while evolving along different paths," Marino says. "What the data say to me is that we, as humans, are not that special. Although we are highly encephalized [have large brains], it's not by much compared with cetaceans." The scientists investigated the fossil r...

Scientists advocate genomic sequencing of 'living fossil'

...s work is that the coelacanth genome appears to be evolving slowly relative to land vertebrates and the teleost fishes. This makes the coelacanth genome a better reference for comparative sequence analyses involving land vertebrates than teleost genomes, which are commonly used for such studies but are highl...

Small seasonal changes can lead to big flu outbreaks

...on rate' are amplified by interactions between the evolving virus and the changing level of immunity that people have to specific strains." Because the influenza virus is constantly adapting, immunity to the flu is not a permanent condition as it is with other viral diseases like chicken pox. Incorporating l...

Genome of ancient fish could reveal evolutionary mysteries, Stanford scientists say

...hese genes that zebrafish lack. "The coelacanth is evolving very slowly, that's what makes them interesting," Noonan said. Although it isn't known why coelacanths evolve so slowly, Noonan suggested that their lifespan might be at issue. Where most fish reproduce quickly and have short generation t...

Computer analysis shows scientists could reconstruct the genome of the mammalian common ancestor

... hypothetical ancestral DNA sequence, artificially evolving the DNA along all the various pathways of mammalian evolution to create simulated modern DNA sequences for 20 different species. Then they used their reconstruction procedure (a completely separate process that incorporates no information from the si...

Study identifies key aspect of immune response against HIV

... have known for some time that HLA-B molecules are evolving more rapidly than other types, but it has been unclear why this is happening," says Goulder. "These data suggest an explanation for the more rapid evolution of HLA-B in response to other infectious diseases, not only HIV. This is an exciting time for...

Research points to new theory driving evolutionary changes

...in many genes are probably responsible for rapidly evolving physical traits that affect a species' ability to survive," Dr. Garner said. "Dogs have been rapidly bred to have many different shapes and traits that are pleasing to humans, enabling them to survive. Humans rapidly evolved big brains, which helped ...

Map of human genetic variation across populations may promise improved disease treatments

But, single-letter variations, called "snips," for single-nucleotide polymorphisms (SNPs), may determine each person's disease-vulnerability and response to different medications, as well as a broad range of other trai...
