My Mongoloid Challenge

AV1611VET · Jan 22, 2018

I'm just wondering if anyone knows if academia ever taught at one time that a human embryo went through three stages of development: first negroid, then mongoloid, then caucasoid?

I've heard this before and am wondering if anyone can confirm it.

I'm sure many will come out of the woodwork to auto-deny it or claim they've never heard that before, but I'm looking for someone who knows what I'm talking about to answer.

Thanks.

As regards the whole human race, yes. Or something like that. But as for an individual fetus, no.

Sounds like a solid southern Christian doctrine to me.

The only things I am finding for any such claim are from anti-evolution sites and creationist blogs.

Never heard of such a thing, and also, "academia" isn't always the monolithic entity that your OP suggests.

Dunno.

I have heard that human embryos have gill slits and webbed fingers/feet at various stages; so my three stages of embryonic development would be:

Fishoid
Duckoid
Humanoid

Somehow I don't think this thread will end well...

In my freshman year of med school (early 70s) we studied human anatomy and embryology pretty extensively. Nothing like that was ever discussed. Could you be thinking of the old idea of ontogeny recapitulates phylogeny? That was a 19th century notion that as an embryo develops (ontogeny) it passes through the forms of its ancestral organisms. In other words, it was thought that it repeats its evolutionary history (recapitulates its phylogeny) during embryogenesis. But that was an erroneous conclusion, based on superficial observation. While it's true that a bird embryo and a mammal embryo go through a stage where they both have slits and arches in their neck that look like the gill slits and gill arches of fish. But these structures never develop into gills. A human fetus directly develops whatever racial features are encoded in its DNA. It doesn't change its racial characteristics during gestation.

So it looks like this challenge of AV's has been defeated then.

Nothing new, as they usually are.

Which weeks are your genetic/physical feature metamorphism occurring?

AnotherAtheist · Feb 24, 2018

The OP only wants people to post if they can support his claim.

I've done a search, and I've found nothing.

HitchSlap · Feb 24, 2018

It seems the OP has left the building.

Do you mean morula, blastula and gastrula?

Do you mean Ernst Haeckel embryo used as evidence for evolution?

Yeah, he is taking a nap. He will be back in a little bit.

Haeckel was an early adherent of evolution by natural selection. Like Darwin, his own biological work was largely observation and speculation. He came up with the erroneous concept of ORP based his misinterpretation of embyrological specimens. But was right about some other things. He was among the first to recognize that some unicellular organisms could not be classified as either plant or animal, and he created the Protist Kingdom. (Which has since been expanded upon.) IIRC, he was also the first (or one of the first) to state that the cell nucleus played the key role in inheritance. Quite an achievement for the 1860s.

You sure about that?
