Darwin was useless, as were his poorly developed, full-of-holes theories, and all of the unfounded conjectures that grew out of them and into the modern scourge of godless humanism.
The “missing link” will never be found, for excellent reason. None exists.
There is no link between chordates and inchordates, no link between primates and homo sapiens, no explanation for the fact that man posses both a thalamus and a hypothalamus, while none of the primates (nor any other species)do...
No explanation (other than fraud) for Peking man, Java man, and 2 - 3 others which turned out to be nothing but boxes of misidentified or deliberately wrongly-categorized remnants...
No explanation but arrogant men seeking a way to worship themselves instead of acknowledging the sovereign G_d.
Attacking the man for the theory he put forward does not substantiate your positioninopposition to his theory.

Absence of proof does not constitute proof of absence. The data set is still incomplete and the Origin of Species remains a theory. Perhaps you could demonstrate your open mindedness by letting us know what standard of proof you require.
I believe the explanation goes something like this: once upon a time long ago a human ancestor, that was non-human, had a random mutation that generated new information in the DNA of one of its sex cells that resulted in a little bud of a thalamus in one of the offspring, though not really yet a thalamus, just maybe one one-thousanths on its way to becoming a fully functioning thalamus. But the environment was such that this bud of a thalamus, which was not a thalamus or anywhere close to a functioning thalamus, somehow benefited the offspring to such an extent that he/she was better able to survive and pass on this mutated gene. The other poor non-humans, not having the one one-thousandths of a thalamus were at such a large disadvantage that they died off. Then over eons of time the same thing happened over and over and over again until, hey, we now have a fully functional thalamus and all the species who had an incomplete thalamus, anywhere from the initial bud of a thalamus up until almost a complete thalamus died off and became extinct. Why there aren't creatures surviving with an “almost thalamus,” I don't know, but there you have it. See?
