SFU helps crack code on evolution

A study in participation with Simon Fraser University researchers has found evidence for decoding how new species evolve to different environments using genetics, or “genomic basis.”

Genomes are the genetic material of an organism.

The study, published in the journal Science Thursday, studied the walking stick insect to figure out how it evolved using different plants.

Using data obtained through the study, researchers found which genes took part in the evolutionary process, referred to as speciation.

“From this we can learn, more effectively than in systems where speciation processes happen only once, how new species arise,” said biology professor Bernard Crespi.

And that information can help discover how nature develops.

“This tells you about the roles of natural selection, and how many genes are involved, in speciation,” Crespi said.
