Evolutionary geneticist Ed Green discusses the key questions researchers hope to answer by analyzing the Neanderthal genome. Anthropologist Tanya Smith explains that invisible microstructure inside teeth creates a durable record of life history, including events such as birth, illness, famine, stress, and death. Anthropologist Jean-Jacques Hublin explains that unlike teeth, bones undergo a lifelong process called remodeling, in which they are constantly being destroyed and recreated. Anthropologist Philipp Gunz explains the process of virtual fossil reconstruction, a technique that can reverse the damage done to fossils by time and the elements. Anthropologist Katerina Harvati explains the rare convergence of circumstances that are necessary for the discovery of a fossil specimen. Anthropologist Jean-Jacques Hublin discusses the role of conflict and argument in the scientific process. Halloween Special Edition! In this zany competition teachers have ten minutes to create a science activity from a special Halloween secret ingredient... bats! Evolutionary geneticist Svante Pääbo explains that analysis of ancient Neanderthal DNA is very tricky work, thanks to fragmentation and contamination of genetic material. Is a single gene, FOXP2, the secret to human speech? Researchers discuss the genetic underpinnings of speech and language. Anthropologist Katerina Harvati explains how scientists from various disciplines work together to find fossilized human remains.
