Other than noting that species survived how were their fitness

First we have to dispose of the several wrong assumptions contained in
the question. It's not species that we're dealing with, but individuals.

It wasn't a CA/bonobo/ape/monkey (choose your vernacular) who gave
birth to a human but a population of simians that turned into a
population of humans ?

Actually, it was the common ancestor, that part has nothing to do with
'vernacular,'by definition. Yes, it was a population that transitioned
into another population.

The fitnesses of species are not measured, but the fitnesses of
genotypes or phenotypes.

Darwin didn't know about genes. Genotype, phenotype, allele and gene
frequencies are not defined .

Sure they are:
http://dictionary.reference.com/browse/genotype
http://dictionary.reference.com/browse/phenotype
http://dictionary.reference.com/browse/allele
http://dictionary.reference.com/browse/gene%20frequency

I'm actually surprised that you say this since I gave you the
definitions a few posts ago.
Aren't dictionaries fun!
Reproductive success is the measuring stick of fitness.

RS is semantics not pragmatics, I don' know what your intent is. We
need to defined RS for example and be told who defined its usage as
some sort of technical concept in biology. Darwin never said
"reproductive success" , which author are you refering to ?

Actually we don't need to know those things, we use a dictionary and
refer to common practice in language.
