There is NO EVIDENCE man was once another species.

There is NO EVIDENCE man was once another species."
By scientific definition you are right. Man was never another species if you mean Homo sapiens. Sapiens is the species and humans are defined as that species, so you are technically correct. Man was never a different Genus, either.
But there are several species that have been discovered in the Genus Homo that are in the branch of human forebears. I am sorry if that fact dismays you, but that is the truth.
But if you hope to argue science, you must understand science. Science is not a court of law and the "verdicts" are drawn by empirical evidence, scientific analysis, controlled experiments and peer review.

HEAR, HEAR!! Good freaking grief...
By definition, our ancestor species were not the same species as Homo Sapiens.
