Pig 135 snuffles and grunts inside his pen. Jon Oatley reaches through the bars to pet the more than 500-pound genetically modified animal.

“People have this image in their head of a pig with deformities, but they’re just normal pigs,” says molecular biologist Oatley ’01 MS, ’04 PhD as he rubs the pig’s ears.

The enormous, three-year-old pig is one of a handful bred by Oatley, director of WSU’s Center for Reproductive Biology, and his team to be surrogate fathers. Through genetic tinkering, Pig 135 is able to produce sperm that contains the genetic material of another pig rather than his own. This … » More …

Another look at Darwin’s finches

Darwin developed key aspects of his theory of evolution while pondering finches from the Galapagos Islands. It’s only fitting that reproductive biologist Michael Skinner would choose those same islands to propose a Lamarckian idea—that environment can directly impact inheritance of physical traits.

In this case, the process is driven by epigenetics, he says. “If we think about evolution, we can’t simply think of genetics. We also need to think about epigenetics.”

According to Skinner, epigenetic mutations occur 1,000 times more frequently than do genetic mutations and could help explain why new species emerge more often than expected.

“The reason epimutations exist might be to dramatically … » More …

Evolution evolution

In a word, Michael Skinner is tenacious. Growing up on a ranch outside Pendleton, the former Eagle Scout and college wrestler learned early on that you don’t back down from a little head-butting or controversy. It’s all just part of the game.

The trait has served Skinner ’82 PhD well over the years and enabled him to persevere through the fallout of a chance discovery in his reproductive biology lab in the 1990s. The unexpected findings threw 200 years of scientific ideology into question and initiated a paradigm shift in the understanding of inheritance and evolution. They also sparked a wave of outrage and … » More …
