how do you explain these:
Phoberomys pattersoni, 3m long, plus additional 1.5m long tail, about 700kg, extinct rodent, related to capibara, lived about 8 Mya?

or Neochoerus pinckneyior, extinct North American capibara?

I want to know why in the hell were there recognizable rodents, crocs, roaches, and Plesiosaurs that existed millions of years ago and still exist today as a species, yet we haven't been a unified species for any longer than 150,000 years. What makes us evolve so fast and them so slow, were they really truly that successful or was our environment that much more harsh? Evolution has a lot of underlying crack pot theories.. I remember watching some crap on the discovery channel about life in 5 millions years from now.. They proposed that humans would be extinct and that land would be dominated by super intelligent Squid.. I'm serious, half of evolution is a joke, the other half is scientifically plausible, but you can't mix fact with imagination and pass it off as a legit theory, it looks foolish and naive.
A. as far as scientists know, plesiosaurs went extinct 65 Mya....
B. your question is why we evolved so fast while other species:
1. we haven't really "evolved fast", phyisiologically we are absolutely the same as most other mammals
most of the "fast evolution" you are refering to has happened on a cultural level because of the development of language, which allowed us as a species to store and transmit information to the next generations
anyway, it took us more than 5 million years to evolve from apes, this is just as slow as most evolutionary events of that scale, because we are not at all as different from apes as you would like to think
2. functional genomics studies show that large portions of mammalian genomes code for non-coding RNA (ncRNA) of various length and in fact the portion of the genome transcribed but not translated increases in close correlation with the increase in organisms' complexity
ncRNAs can evolve much faster than proteins, because they are not limited by the genetic code as proteins are, there are no stop codons and nonsense mutations and very little damage can be done by substitution of bases
in the same time almost every RNA has a secondary structure and this structure is usually critical for its function, it is easy to see how ncRNAs can evolve fast
so far several ncRNAs have been found to play key role in synaptci transmission and hundreds of brain-specific miRNAs have been indentified
of course, these are findings from the last 3 years, so we certainly have a very limited understanding of what's going on, but that's the picture that's emerging

Rather extremely ignorant, all I have to say is... MICROEVOLUTION. The evolution of micro-organisms such as viruses, bacteria and microbes. It can be observed on a daily basis and is FACT.
Extremely ignorant. Apparently there are actually many Creationists in America who think evolution states that man evolved from a monkey, I saw them on TV, it was funny. They think evolution is an outdated picture of an ape morphing into a man... no wonder they don't "believe" in evolution. These fucktards have no idea what evolution is.

species: can fuck and successfully reproduce viable offspring that can also reproduce etc
speciation: one species eventually gives rise to a NEW separate species that can reproduce with others of the new speices, but not with the species that gave rise to to it.
speciation, as ive pointed out, is a fact, has been recreated in lab settings, and is taught in introductory biology classes in high school.
and your definition of evolution is conveniently set up so it can never be proven in one human lifetime, or five, or ten, but would require billions of years to replicate exactly what has happened until you are satisfied. and so i agree, with that definition it will never be proven. but all the evidence is there, its the strongest theory we have, all new info and research we have supports it, the majority of those in biology (ie the experts) take it as fact. if people want to play semantics, then NOTHING can ever really completely be proven because the future is unknown and could "prove" otherwise.

lol. like funk master five said, this is ignorant. The only ones saying that human beings evolved from monkeys are creationists using the straw man fallacy to try to argue against evolution. Nobody who understands evolution and takes it as fact says man evolved from monkeys. so are you the ignorant one, or were you trying to make a point?
