Links, old and new
First, paleontologists in Spain have found a 13-million-year-old fossil that may be the link between the line that developed into Homo sapiens and the one that developed into great apes. The Smithsonian's Human Origins Program has a phylogenetic tree [Wikipedia] of human ancestors going back 5 million years. Some scientists doubt that this fossil represents our common ancestor, but it will be an interesting story to watch.
Second, The Washington Post has a report on hybrid animals being created using human stem cells.
In Nevada, there are sheep whose livers and hearts are largely human.
What to do?
