"I do not know of any credible evidence that suggests Dr. Zavos can clone a human being. This seems to be yet another one of his claims to get publicity"

This quote by Robert Winston suggests that there is no trustworthy evidence to support the claims of Dr. Zavos that he can clone a human being. Winston indicates that Zavos is making these claims in order to get promotion, instead of due to the fact that he has any real proof to back them up. This implies that Zavos is not a reputable source and that his claims ought to not be taken seriously. Winston's quote also suggests that cloning a human is not yet a reality, which any claims to the contrary need to be viewed with uncertainty. In general, Winston's quote indicates that Dr. Zavos' claims must not be taken seriously, which any proof he offers need to be completely analyzed before being accepted as true.
