Well, intuitively have always looked back upon the history of the human race from its dawn of civilizations as a multi faceted, interconnected set of circumstance, all taken together in the enitre net of understanding can intimate/reflect an "intelligence". Nothing has spurred that world of discovery, human intelligence more than the arms race, developement of fortifications, weapons of war, of conveyance, communication, though there's other aspects to be considered, this has been the greatest of motivators, protection of territory.

One sees originally raw hunter/gatherer scavenger mode, which can be quite plentiful for an opportunist but over wide distances of time, many migrations, ups & downs, many adaptations to geography & food source. Civilizations & human productivity is tied to that surplus that builds with the cultivation & storage around the great river systems. Is it intelligent design that humans congregated around the great rivers & fertile lands or by the coastal areas of the world where food was plentiful?

Here more specialized skills arose, with that storage of grains thru agriculture there was the essential surplus energy for man to become more expeditious, you have the rise of civilizations like the Egyptian that had more history than the western world has. There was the earlier Mohenjo Daro Indus valley civilization that they find few weapons of war, prolly existing peacfully until swept down on & conquered.

Something as incomprensible as the idea of "nothing from nothing" is similarly hard for us to understand that chemical evolution leads to consciousness & life is a natural outflow of this universe's set of quanta values. You say chemicals do not store information, cannot evolve, the famous chemist is struck dumb with awe that this exists. Good for you & him, hes not the only one,you're free to believe whatever about master wizard creators, its not the whole story.

As with evolution of life, one doesn't deny that we've seen certain modifying behaviors come to exist thur time, to say its all because of "christian values" is to miss the bigger picture, the truth of that continuum and adaptation.

There was a modifying trend, the Assyrians were fierce warlike destroyers, so were their gods that reflected that mindset, the Egyptians not so much but later were forced to become more warlike & prosecute against the Assyrians. Baylonians again, still primitive but coming along well with building Law & Order, the Persians rise up actually not the bad guys we think, the Greeks had plenty of slavery & barbarism, though democracy was good, people flourished well under the Persian and here much of the OT comes.

Later we see the culimination in the Roman Empire, then another wave of disolution in the human experience, all the while the arms race is constantly going on. Christianity is as much a product of that process as all the rest.

Big Bang of Evolution Moved at Warp Speed

Evolution during the “Big Bang of Evolution,” also known as the Cambrian Explosion, happened at five times the rate it occurs today, according to a new study, a finding that is consistent with Darwin’s theory of evolution.

The Australian researchers said they’ve been able to estimate, for the first time, just how fast life evolved during an incredibly productive period in Earth’s history some 520 to 540 million years ago. It was during this Cambrian explosion when most modern animal groups first appeared on Earth.

The research group’s findings, published in Current Biology, also provide an answer to Darwin’s dilemma.

In his classic book “On the Origins of the Species,” where he lays out his theory of evolution, 19th century scientist Charles Darwin pointed out a potential problem with his theory.

While there was a rich fossil record of creatures dating from the beginning of the Cambrian Period, Darwin thought a lack of fossils from the years prior to that geologic time period might present a contradiction to his evolution theory.

“The abrupt appearance of dozens of animal groups during this time is arguably the most important evolutionary event after the origin of life,” says lead author and associate professor Michael Lee of the University of Adelaide in South Australia.

Critics of Darwin’s theory of evolution have pointed to the nearly impossibly fast rates of evolution to discredit Darwin’s work.

Up until this new research, no one has been able to accurately measure the rates of evolution during this prolific period because of the “notorious imperfection” of the ancient fossil record.

In this new study, the researchers said that they were able to estimate that rates of both structural and genetic evolution of creatures that took place during the Cambrian explosion were five times faster than they are today. The scientists say these changes are also consistent with Darwin’s theory of evolution.

The researchers focused their work on invertebrate animals called arthropods because they considered them to be the most diverse animal group that existed both back during the Cambrian period as well as today. This group of animals includes insects, crustaceans and arachnids.

“It was during this Cambrian period that many of the most familiar traits associated with this group of animals evolved, like a hard exoskeleton, jointed legs and compound (multi-faceted) eyes that are shared by all arthropods. We even find the first appearance in the fossil record of the antenna that insects, millipedes and lobsters all have, and the earliest biting jaws,” said co-author Dr. Greg Edgecombe of London’s Natural History Museum.

Cambrian explosion was indeed marked by lightning-fast evolution
nbcnews.com


The team found that the emergence of many sea creatures during the Cambrian explosion could be explained by an accelerated — but not unrealistic — evolution by way of natural selection, or the process in which organisms change over time due to changes in heritable physical or behavioral traits. (For instance, changes that give an organism a leg up will help it survive to pass down that trait to offspring.) The team focused its study on animals related to arthropods, the group that includes crustaceans and other insects.

"In this study we've estimated that rates of both morphological and genetic evolution during the Cambrian explosion were five times faster than today – quite rapid, but perfectly consistent with Darwin's theory of evolution," Lee said.

For every Dawkins, you'll still have to account for 10,000 other scientists, good luck with discrediting them all on your litttle crusade, but be well advised to place your efforts elsewhere.
