Fuzzy bears!
Perhaps it does suggest what you say, but considering the less than 200 years since the theory of evolution was proposed is an extremely short period of time, in the context of that theory; and considering we neither know every species on the planet now nor all those that have existed prior to now; and considering we cannot keep track of every place or every animal on the planet, it seems only a small suggestion.
"...but considering the less than 200 years since the theory of evolution was proposed is an extremely short period of time,..."
1. The less than 200 years is one factor.....combined with the factor of how many scientists are at work currently.
a. ...and the fact that one loses grants, status, and livelihood if one posits that Darwin was wrong.
2. Darwin said this:
“Why, if species have descended from other species by insensibly fine gradations, do we not everywhere see innumerable transitional forms.”
“Consequently, if my theory be true, it is indisputable that before the lowest Silurian stratum was deposited, long periods elapsed, as long as, or probably far longer than, the whole interval from the Silurian age to the present day; and that during these vast, yet quite unknown, periods of time, the world swarmed with living creatures.To the question why we do not find records of these vast primordial periods, I can give no satisfactory answer.”
Darwin, "On The Origin of Speices," chapter nine
“The case at present must remain inexplicable; and may be truly urged as a valid argument against the views here entertained.”
“The several difficulties here discussed, namely our not finding in the successive formations infinitely numerous transitional links between the many species which now exist or have existed; the sudden manner in which whole groups of species appear in our European formations; the almost entire absence, as at present known, of fossiliferous formations beneath the Silurian strata, are all undoubtedly of the gravest nature.”
3. This is the heart of Darwin's thesis:
. The universal common ancestry of all living things: all had a single common ancestor way back in the distant past..."all the organic beings that have ever lived on this earth have descended from some one [ONE SINGLE] primordial form" (Darwin, "On The Origin of Species," p.484.)
There are numerous examples which show the very opposite of Darwin's theory.
"The Chengjiang fauna makes the Cambrian explosion more difficult to reconcile with the Darwinian view for yet another reason. The Chengjiang discoveries intensify the top-down pattern of appearances in which individual representatives of the higher taxonomic categories (phyla, subphyla, and classes) appear and only later diversify into the lower taxonomic categories (families, genera, and species).
Meyer, "Darwin's Doubt," p.74
The sudden appearance of complex organism.....followed by simpler.
So...if Darwin were correct, the opposite would be true...and we'd find in Chengjiang, and in sites such as the Burgess Shale in Britain, simpler categories early and the more developed, later.
This is not the case.
Does anyone claim that Darwin was correct in all aspects of his theory? Evolutionary theory has changed over the years.
"Evolutionary theory has changed over the years."
Would you mind supporting your claim?
I don't want to get into an in depth debate on evolution, but clearly we have knowledge of things related to evolution which were unavailable, perhaps unimagined, in Darwin's time. Our understanding of DNA, for example, was something Darwin did not have. As such, he could not take it into account in his theory.
Here, though, is a simple search which gives plenty of different sites to look at on the subject :
how evolutionary theory has changed since darwin at DuckDuckGo
Whether one believes in evolutionary theory or not, it clearly is not exactly the same as what Darwin proposed.
I need no "different sites to look at on the subject..."
I'm an expert on the subject....as shown by the fact that every single thing I've posted is correct and accurate.
And....rather than hot air....whenever you're ready....provide changes in Darwin's theory that are presented to students.
An expert on the subject?
You have fun with that. I provided what you asked for, that being evidence that evolutionary theory has changed since first proposed by Darwin. I both gave an example of how human understanding has grown regarding subjects directly related to evolution, and I also gave a link to a search about how evolutionary theory has changed since Darwin. If you are unable to see that this is just what you asked for, you might want to rethink your claims of expertise. Actually, you should probably rethink those claims either way.
