The Missing Link That Wasn’t

  • The myth of the Missing Link--the idea that there must be a specimen that partly resembles an ape but also partly resembles a modern human--is persistent. But the reality is that there is no missing link in our lineage, because that’s not how evolution works.

                      "linear" or not, evolution is clearly at work when you look at the river otter. Then look at the sealion/fur seal. Then look at the seal. Finally look at a dolphin/whale.

                            @Konceited Kai The only way you can know the existence of something is by evidence thereof. The human imagination can conjure up all manner of entities without the need for corroborating evidence. There have been something like 3000 "supernatural entities" proposed by various cultures with not a shred of evidence for any of them.

                            Randall Wilks, I beg to disagree, it more likely that another species, more advanced than our species died out in a mass extinction just 10k years ago.

                            We are the sole survivors of six million years of hominin evolution. Every person on earth is 99.9% genetically identical to everyone else. Our last competitor died out only 40,000 years ago.

                              There’d still have to be a discovery of a human-ape ancestor for this model to work. Otherwise, these are just humans with slightly different physical genes than the modern humans today. Many people have many skull shapes, and certain cultures do things to accentuate their skulls and other things. I can’t see how this does anything for the theory of evolution

                                Donovan poses an argument from ignorance; he cannot understand the evidence, therefore it cannot be true.

                              It's pretty nuts that all these subspecies always seemed to be able to interbreed, and like, every dog, ever; and lions and tigers, etc; Yet those finches on the Galapagos weren't able to, after only a few decades on different islands. Assuming I'm remembering right..

                                The difference between neanderthals and homo sapiens is comparable to the same amount of difference between an asian man and a european man. Or the amount of difference between a Nordic man and an Egyptian man... They are often unnecessarily made to be so contrasting when it's not the case.

                                  @The Goddamn Batman You're missing the point.

                                  I should have specified and said, "Where as other people may have _just_ Cro-Magnon DNA. And some people have Cro-Magnon and Neanderthal DNA".. Both are fully formed humans with slight distinctions from one another.

                                  @Derek Lowery A "Cro Magnon" is just an early modern human. We all have that in our DNA. JS

                                  @Abraham David González González The reason that some people have Neanderthal DNA is merely due to a different lineage based on region. Where as other people may have Cro-Magnon DNA instead.

                                  Similar to how a persian cat and a siamese cat look relatively different but are both species of pet cat.

                                  @Abraham David González González I'm not saying that they are the same. I'm saying that the amount of contrast between them is overexaggerated. And that the difference between them is no more disparate than the examples I listed above.

                                It will be of great help to our understanding of the different races of humans if we learnt how they evolved to looking like they do now, tracing their roots from Africa to Europe, India China and Arabia. That would be one really informative episode that people would love to watch. Please consider.

                                                          The model itself is fine. It is linear if you only look at one line of lineage in a species then it WILL be linear. However, in order to do that you have to ignore all other related lineages.
