As Smokey said, those are not true 'ladder' charts.... they 'indicate' the best current guesses, given the sparsity of archeological evidence. Anyone who looks at one and suggests or believes that "science is sure it was that way" mistakes how science works.
And if those who made those charts think that way, they will likely have to eat one of those charts some day.
The charts and evidence ARE getting closer...I remember when Piltdown Man was still taken seriously, and I have seen the TV documentaries on evolution and cosmology revised over & over just in the last 20 years.

Sadly, I have not seen theology change much in that time.
