Neanderthals Were Seperate Species, Says New Human Family Tree

YOu’re right, but for people like me, who weren’t keeping up when they changed the terms, it was a little difficult to catch up! ;)

Wikipedia....

The ligon is not really fertile......

“While male ligers are sterile, female ligers can usually reproduce[citation needed]. Because only female ligers and tigons are fertile, a liger cannot reproduce with another liger or with a tigon. The sterility in males is caused by the fact that because of the unstable genes, male ligers never reach puberty. While they continue to age and grow they do not become sexually mature”

[brytlea]

So, actually, it would be possible to a species to diverge into to different species, but then thru some sort of environmental change, become one species again thru interbreeding?

Still, as I said, some are fertile.

You will be happy to know your are now considered a purebred.

Neanderthals are from Mars/Cromagnons are from Venus.

[Coyoteman]

So, am I right that no direct ancestor for homo-sapiens has ever been discovered? All that were conjectured as that immediate ancestor have been proven not to be?

No, you are wrong.

Here it is, they used a turkmen jackal for it.

Ahhhh...thank you! I was trying to find something about that dog-jackal hybrid. I was thinking of it when mentioning the Russian dog-fox hybrid.

The Golden or Common Jackal (which includes the "turkmen") is species Canis aureus. Wolves and dogs are species Canis lupus. So the Russian hybrid is an example of two different species being able to interbreed.

There are plenty of other examples, including horses and zebras

Don’t know if your interested, but I found this and thought it interesting:

Ya gotta love how those lines fade out here and there on the chart.

They're working on it.

But that is the difference between creationism and science, although some are trying to blur those differences.

Science starts with questions and seeks answers. Creationism starts with answers and discourages questions.

[MrB]

Atheists ALSO start from an answer and use “science” to justify it, and “discourages questions”.

And, they use the courts and other forms of coercion to make sure that only their viewpoint is taught to our kids in public schools.

"Yeah Daddio, a whole new species...groovy!"

[allmendream]

Yes, it would be possible if two species diverged due to environmental differences (low mountain vs high mountain) maintained reproductive isolation from the other population (one mates in early spring the other in late spring) to form a third species in a different environment.

...gotta love these threads......

That was Heidelberg man ~ Neanderthal buried or otherwise disposed of the dead.

Sorry Blam, that’s ISLAMIC RAGE BOY.

Typing without glasses ticket for me.

This stuff is always interesting!

Virchow started this kind of nonsense, and it hasn't improved with age. IMO.

But anyway, looky, it's the third time in a week:

The Neandertal Enigma
by James Shreeve

Frayer's own reading of the record reveals a number of overlooked traits that clearly and specifically link the Neandertals to the Cro-Magnons. One such trait is the shape of the opening of the nerve canal in the lower jaw, a spot where dentists often give a pain-blocking injection. In many Neandertal, the upper portion of the opening is covered by a broad bony ridge, a curious feature also carried by a significant number of Cro-Magnons. But none of the alleged 'ancestors of us all' fossils from Africa have it, and it is extremely rare in modern people outside Europe." [pp 126-127]
