JW: That of itself is very interesting, Gerrit. But I was
really interested in later H. erectus fossils. Perhaps
there aren't any.

Most modern humans have an ancestral background in which
polygamic mating systems were normal. These tend to produce
sexual dimorphism, which explains why it still exists
today. The impact of two thousand years of Christian
monogamy haven't made much impact yet. The fact that early
H. erectus had similar dimorphic qualities gives us an
insight into the habitat of that species.
