Jan 11 - Professor Moses Schanfield - Where Did We All Come From? Tracing Human Migration using Genetic Markers

Of all species on the face of the earth, humans are the most disperse, in that they occupy the most diverse eco-systems present on all large land masses and most large islands.
In recent time, much work has been done using maternally inherited mitochondrial DNA, and non-recombinant Y (NRY) chromosome markers to map human migration and ancestry.  In addition, large numbers of other DNA based markers have been used for similar purposes.  However, anthropological geneticists have been looking at human migration and ancestry for as long as there have been genetic markers, starting with the ABO blood groups.

Nov 9 - Sharon Hill - The World of Weird News: Bigfoot, UFOs and Other Questionable Claims

Weird news is its own niche on the web and in print. The more sensational the story, the more eyeballs it gets. Topics include Bigfoot and UFO sightings, hauntings, exorcism, witchcraft, mysteries, miracles, psychic predictions and conspiracies. We are barraged with claims that are seriously questionable. While entertaining, many people actually believe this stuff.  This is a fun tour through weird and wonderful news stories and an examination of how we think about doubtful news and the impact it has on society.

Sharon Hill is a writer, researcher, and consultant specializing in Science and Society issues. As creator and editor of the unique news and commentary site, DoubtfulNews.com, she advocates for a genuine skeptical take on alternative medicine, the paranormal, anomalous natural phenomena, cryptozoology and other weird news as well as promoting a rational, scientific outlook on these topics. With the help of other prominent skeptics, she spearheaded the "Media Guide to Skepticism" to explain the core of the philosophy and method of skepticism. Her current focus is on the "sham inquiry" of amateur paranormal investigators and their use of scientific language and activities to appear credible to the public. She is a licensed geologist in Pennsylvania and has 20 years experience in environmental regulations and policy.
