UCLA biologists report how whales have changed over 35 million years

Alfaro's laboratory uses many techniques, including the analysis of DNA sequences, computational techniques and the fossil record to analytically test ideas about when major groups appear and when they become dominant. He and his research team integrate information from the fossil record with novel computational methods of analysis.

"We are interested in understanding the causes of biodiversity," Alfaro said.

"If we really want to understand species diversity, the number of species in any given group and how the variation in body size came to be, this paper points out that we will need to rely on more of a collaboration between paleontologists and molecular biologists to detect possible changes in the rate at which new species came into existence," Slater said.

The analytical tools for integrating the fossil data with the molecular data are just being developed, said Alfaro, whose research is bridging the divide.
