A highly conserved yeast homologue of P1W1 protein was shown to act biochemically as would be expected for a protein with a role in RNA processing, as predicted by the algorithm. "We examined the extent to which [transcriptional co-expression] is effective for our data...Chicken genomic sequence yields insight into vertebrate evolution

While splicing has largely been conserved over evolutionary time, another interesting biological mechanism namely, genomic imprinting appears to be restricted to more evolutionary advanced clades. Genomic imprinting, or parent-of-origin-specific gene expression, is thought to be governed ...Draft sequence of chicken genome completed

...n. They compared these human sequences to regions conserved over time in other vertebrate genomes, including chimpanzee, dog, mouse, rat, chicken and pufferfish to shed light on changes that have occurred since the last common ancestor, ranging from five million to 400 million years ago.

The researchers did not find an excess of changes in these genes during human evolution. This provides a sharp contrast to the tremendous excess of changes in the brain...
