there is and there is
let's start with the fish
[Link: tiktaalik.uchicago.edu]This is from Wikipedia
[Link: en.wikipedia.org] "Paleontologists SUGGEST that it was an intermediate form between fish such as Panderichthys, which lived about 380 million years ago, and early tetrapods" but they don't know for sure. These people are guessing and as Tom stated there is no conclusive evidence.
These same paleontologists claimed for the longest that humanoids and Neanderthals did not coexist. That neanderthals where the precursor for humanoids.
[Link: abc.net.au] "New evidence has emerged that Neanderthals co-existed with anatomically modern humans for at least 1,000 years in central France."
[Link: accessexcellence.org]"New evidence from mitochondrial DNA analyses indicates that the Neanderthal hominid was not related to human ancestors."
Most of us don't disagree on evolution as "An Origin of Species" but evolution can not be tested as to being the source of life. Yet the evolutionist want it taught in school as the end be all to the answer of where life came from and that's not very scientific.
