Must be... so that scientific observation can remain within what you call "micro-evolution", huh?

Indeed you did... I'd forgotten:

No intermediary species? I wonder how someone could come up with this graph:
(it's huge, so I'll hide it)
Here are some examples from our own evolution:

Can you not see the features developing from top to bottom?
Brain size increases, jaws recede and become smaller? no? can't see it? I doubt you can't see it... considering how you can comprehend the complexity in DNA...

There is a big problem in sexually reproductive species, when they have a single breeding pair. Cheetahs were (or still are) close to this situation. http://Inbreeding results in homozygosit...as inbred.
So, it seems very unlikely that any species, humans included, were ever limited to a single pair of breeding specimens. It would have always been a population-wide effect.

That would be mitochondrial RNA that is only passed down in the egg from the female side.
And, if I remember correctly, they've traced mitochondrial RNA back to an African population... not a single person
