Stanford researchers with collaborators at Tel-Aviv University have now laid the foundation for opening a window to the past using a technique called "reverse ecology." The technique uses genomic data to examine metabolic networks and pulls out proxies for reconstructing bacterial environments millions of years in the past. The work, published in the February issue of the Journal of Computational Biology, offers clues to the complex evolutionary interplay between organisms such as parasites and hosts.

Sarah A. Tishkoff, PhD, David and Lyn Silfen University Associate Professor, will present "Evolutionary History of Modern Humans in Africa. In honor of Darwin's 200th birthday on February 12, Tishkoff's talk will focus on the process of evolution due to natural selection using examples from recent human evolution.

There are two species of lice that infest humans: pubic lice, Pthirus pubis, and human head and body lice, Pediculus humanus. A new article in BioMed Central's open access Journal of Biology suggests one explanation for the separation of the two species.

Our surnames and genetic information are often strongly connected, according to a study funded by the Wellcome Trust. The research, published this week in the journal Molecular Biology and Evolution, may help genealogists create more accurate family trees even when records are missing. It also suggests that the often quoted "one in ten" figure for children born through infidelity is unlikely to be true.
