UC San Diego bioinformatics experts help reconstruct the genomic makeup of our ancestors

...uillaume Bourque of the University of Montreal. It depicts the course of evolution for the X chromosome in humans, rats and mice from a common ancestor over 80 million years ago and, for the first time, reconstructs the genomic architecture of mammalian ancestors. "It contributes to the solution of the so-ca...

New genomic data helps resolve biology's tree of life

...answers so that one gene from a group of organisms depicts one tree, while a different gene from the same organisms will paint an entirely different phylogenetic picture. More genes, it has been thought, could help resolve the issue, and the new Wisconsin study now provides the first glimpse at both just how...

Key sensory proteins unveiled in mosquito genome found by Illinois entomologist

...es. Their work resulted in a phylogenic tree that depicts which receptors are in both genomes and which ones are in just one genome. The researchers conclude that while many of the receptors found in both insects are roughly equivalent, they evolved largely separately. "In other words," Robertson said, "th...

University of Cincinnati geologist finds survival benefit to evolving after mass extinctions

In the future, he hopes to use these data to assess directly whether the longer-lived genera really...

Neuroscience contest prompts 'thinking about thinking'

... there is no direct evidence that Hopfield's model depicts what actually happens in human brains or those of other animals, he believes it is likely to be very close. "I think we are going to find that the way this simulated brain computes is an example of the way a whole lot of real organisms compute," he s...

Ancient math refines theories of evolution

Currently, scientists are forced to treat evolutionary trees as ironclad truth, even though the results from different studies often disagree with one another. Bayesian mathematics accommodates un...
