People in Africa are more genetically diverse than the rest of us. Closer dna with Cameroon could be the result of a backflow as much as anything else ?

When two groups of the same species separate from each other, for whatever reason, they start to diverge, though the differences may be slight.

A bit like the German shepherd and the Alsation dog breeds. Doggy specialists would argue that they are two separate breeds, but to the untrained eye. They look the same. One breed having a sloping backbone dosen't make it obviously different enough to call it a separate breed.

put us in a box or stable, interbreed only those, who look like you want them to look and wait - then we'll have human races as well. There is no different then between humans and other animals.
But I was not aware, we are doing this or somebody is doing this with us. That's why we have no races.

Races are not made up. They existed because of biodiversity, which is a natural thing. Polar bears are a different race from brown bears, not because they chose it . Same goes for Eskimoes and South Africans.

Where I read about face characteristics. That reminds me to brachykephal, mesokephal and doliokephal. It was thought, that a change of head forms in a population is an evidence for a population exchange or at least a migration. We know today, that it has to do with food in many cases. I unfortunately have no sources in the moment.

polar bears and brown bears are different species, not different races, Ursus (or even Thalasarctos) maritimus and Ursus arctos.

Biological definitions of race (Long & Kittles 2003) Concept Reference Definition Essentialist Hooton (1926) "A great division of mankind, characterized as a group by the sharing of a certain combination of features, which have been derived from their common descent, and constitute a vague physical background, usually more or less obscured by individual variations, and realized best in a composite picture." Taxonomic Mayr (1969) "A subspecies is an aggregate of phenotypically similar populations of a species, inhabiting a geographic subdivision of the range of a species, and differing taxonomically from other populations of the species." Population Dobzhansky (1970) "Races are genetically distinct Mendelian populations. They are neither individuals nor particular genotypes, they consist of individuals who differ genetically among themselves." Lineage Templeton (1998) "A subspecies (race) is a distinct evolutionary lineage within a species. This definition requires that a subspecies be genetically differentiated due to barriers to genetic exchange that have persisted for long periods of time; that is, the subspecies must have historical continuity in addition to current genetic differentiation."

Which Inuit? Which South Africans? Genetical research has shown, that some of your races have a greater genetically difference between them, then some of them to other "races".

subspecies = race. Read my wikipedia link.

subspecies is e.g. Canis lupus familiaris,
But modern science doesn't use race for subspecies, but just for breeding forms.
