Popular presentations of human evolution show a rather smooth transition of fossils leading to modern humans.
The impression given is that the dating of the individual fossils in that sequence is accurate enough to establish human evolution as a fact.
Other critics, perhaps more familiar with the data, question certain aspects of the quality of the fossil record and of its dating.
These skeptics do not provide scientific evidence for their views.
On the other hand, the abundance of argon in the is relatively small because of its escape to the atmosphere during processes associated with volcanism.New discoveries have filled in the gaps, and shown us in unimaginable detail the shape of the great ‘tree of life’.Darwin and his contemporaries could never have imagined the improvements in resolution of stratigraphy that have come since 1859, nor guessed what fossils were to be found in the southern continents, nor predicted the huge increase in the number of amateur and professional paleontologists worldwide.However, because of severe dating problems which are seldom mentioned, this alleged sequence cannot be maintained.To present the fossil evidence as a relatively smooth transition leading to modern humans is akin to intellectual dishonesty.
