darwin´s doubt

”Despite the scope of his synthesis, there was one set of facts that troubled Darwin—something he conceded his theory couldn’t adequately explain, at least at present. Darwin was puzzled by a pattern in the fossil record that seemed to document the geologically sudden appearance of animal life in a remote period of geologic history, a period that at first was commonly called the Silurian, but later came to be known as the Cambrian.
During this geological period, many new and anatomically sophisticated creatures appeared suddenly in the sedimentary layers of the geologic column without any evidence of simpler ancestral forms in the earlier layers below, in an event that paleontologists today call the Cambrian explosion.”

 Stephen C. Meyer. ”Darwin's Doubt.” HarperCollins

Darwin hoped that in the future scientist would find more evidence and evidence they found.

if you look at cambrian wiki page http://en.wikipedia.org/wiki/Cambrian you can see that animals and life were really simple, and everything lived in the sea, nothing on the dry land.

ø The Ediacaran Period /ˌdiˈækərən/, named after the Ediacara Hills of South Australia, is the last geological period of the Neoproterozoic Era and of the Proterozoic Eon, immediately preceding the Cambrian Period, the first period of the Paleozoic Era and of the Phanerozoic Eon.


now Darwin did not know anything about this period because the fossil evidence was so sparce that it was ratified only a few years ago.

ø The Ediacaran Period's status as an official geological period was ratified in 2004 by theInternational Union of Geological Sciences (IUGS), making it the first new geological period declared in 120 years.[3]


Animals on the Ediacaran Period were multicelled, but really small and really soft. They did not have trilobian hard shells so they did not leave much evidence to the fossils. Only modern science can collect evidence of the period, that´s why everything we know of the period, is quite new. too new for Stephen Meyer to know about...


Before Cambrian explosion, there was an Avalon explosion of life in Ediacaran period. So when ever there is a possibility and room for life to spread, life evolves and multiplies exponentially until a disaster hits - no room for the weak.

The Ediacara biota radiated in an event called the Avalon Explosion575 million years ago.


so cambrian explosion was not even the first explosion as Stephen claims, life did not suddenly come from nowhere in the cambrian explosion! anyone with any skill on wiki research can find this out. but not if you want to prove you presupposed point!


ø The Avalon Explosion (named from the Precambrian fauna of the Avalon Peninsula) is a proposed evolutionary event in the history ofmetazoa. It is the equivalent of the Cambrian explosion for the Ediacaran biota, and it happened around 33 millions of years earlier.

It was proposed by Virginia Tech paleontologists through the analysis of the morphological space change in several Ediacaranassemblages.[1] The discovery suggests that in the early evolution of animals, there may have been more than one explosive event.[2]The original analysis has been the subject of dispute in the literature[3][4][5]

The Avalon explosion appears similar to the Cambrian explosion by the rapid increase in diversity of morphologies in a relatively small time frame, followed by diversification within the established body plans,[1][6] a pattern similar to that observed in other evolutionary events.

I have to remind here that in that era, one generation did not last long. animals were not living foryears and years, they were short lived, thus evolution was really really fast.

¨

”The abrupt appearance of such complex anatomical designs presented a challenge to each of the two main parts of Darwin’s theory of evolution.”

Well, now I have explained the complexity of trilobytes so you are dismissed Stephen.


p.s. many people opposing evolution seems to think 33 million years is SUDDEN! 


REALLY?? 24 million years ago our ancestor was a small ape called  Kamoyapithecus.

and remember that each generation of an ape is not a week or a month, but a decade at least!

6 million years ago humans were small brained small primates that ate bugs!! (along with other things...)


thank you stetphen but you know you are inventing truth´s here.

”More significant changes to the form and anatomical structure of organisms would, by the logic of Darwin’s mechanism, require untold millions of years, precisely what seemed unavailable in the case of the Cambrian explosion.”

Really, Really? the cambrian explosion part took 40 MILLION years. One bacterian generation is about 24hours... Precambrian animals had really short lifespan so they had nearly limitless timespan to evolve in the sea that had basically unlimited space to diverge and to multiply. and Cambrian period was just a follow up to avalonian explosion.


you have to explain your point if it is unbelievable. you dont.
