Indeed. It appears that Todaro was practicing what the
scientific community refers to as "trying to build a house with toothpicks,
instead of from the logs that the toothpicks came from". Todaro emphacized
the fact that the _total_ baboon-C virus sequence was missing in humans, but
he down-played the fact (if not out-right ignored it) that a _portion_ of
the virus _was_ found in our DNA. I guess if someone wants to provide some
"evidence" for isolation away from Africa, then I can understand Todaro's
motives. However, I don't think that Todaro's conclusions in any
subsequent publications after his _Nature_ are particularly good science.
Now...about Morgan. She did not practice particularly good science, either.
Apparently, either she didn't read the _Nature_ article, OR, she did read
it, but committed the same crime as Todaro did, and ignored the presence of
the p30 protien in humans. If Morgan simply used Todaro's later, biased
conclusions as facts, then Morgan has practiced sloppy research and
referencing.
