Darwin- would he have changed his theory?

Four billion years is enough time for evolution to occur though,so how does this support your contention?

[W]hen people thought the Earth was flat, they were wrong. When people thought the Earth was spherical they were wrong. But if you think that thinking the Earth is spherical is just as wrong as thinking the Earth is flat, then your view is wronger than both of them put together

Why does it not make sense? You also have the time-line a little off As the evidence stands this chart approximates the dates of life in orderr of their appearance.

Millions of Years Since First Known Appearance (Approximate) Microbial (procaryotic cells) 3,500 Complex (eucaryotic cells) 2,000 First multicellular animals 670 Shell-bearing animals 540 Vertebrates (simple fishes) 490 Amphibians 350 Reptiles 310 Mammals 200 Nonhuman primates 60 Earliest apes 25 Australopithecine ancestors of humans 4 Modern humans 0 .15 (150,000 years)

It is obvious that life does require time to accomplish the stages neccesary to the development of complex creatures such as ourselves but once the multicellular level is reached the process is quite accelerated and this does make sense.

How does this make sense?

Well for one the cells are now specialized.This allows for greater capabilities and hence a survival advantage.Since cells are specialized the organism can now devote those specialized cells to specific tasks and now the evolution of further cell specialization is greatly enhanced.
