Charles Darwin worried about a possible hole in his theory of evolution, but some American scientists may just have plugged it. For about a billion years after the dawn of life on Earth, organisms didn't evolve all that much.
Then about 600 million years ago came the "Cambrian explosion." Everything changed relatively quickly, with all kinds of plants and animals emerging—which doesn't quite seem to fit with Darwin's theory of slow change, hence "Darwin's dilemma." Now, within a few days of each other, two new studies have appeared that could explain the shift, ABC News reports.
One, by scientists at Yale and the Georgia Institute of Technology, suggests that oxygen levels may have been far less plentiful in the atmosphere prior to the Cambrian explosion than experts had thought.
The air may only have been .1% oxygen, which couldn't sustain today's complex organisms, indicating a shift had to happen before the "explosion" could take place.
In a separate study, a University of Texas professor explains where that oxygen burst may have come from: a major tectonic shift. Based on geological evidence, Ian Dalziel believes what is now North America remained attached to the supercontinent Gondwanaland until the early Cambrian period, in contrast with current belief, which has the separation occurring earlier.

Fiddle. My question is why did some fish leave the ocean to become land mammals and some land mammals leave land to become fish mammals ..... as we were taught.
This should be interesting.
This time, I’ll just grab some popcorn...
Was the evolution speeding right along in the deep ocean -- you know, where all the nutrients already were? Or was that also pretty much a steady state? If the nutrients in the ocean weren't leading to an explosion of new life forms there, then why did those nutrients, once released from the deep, lead to an explosion of new life on land?
This is all conjecture. Science has become the art of interesting guessing.
Sounds like the Hand of God to me.
Interesting. Thanks for posting.
The air may only have been . . . . oxygen burst may have come from . . .
Yea, that's science . . .
Ping a ling.
I’d say the biggest hole(s) to resolve are (1) How did life first originate? (and don’t give me that primordial soup without some hard facts) (2) How does evolution work to give us eyes and hands that work just where we need them? (3) How does the genetic material from a one-celled organism enlarge itself to EVER become an elephant/human?
They probably just felt like doing it...
They still can’t figure out the eyeball in the lowest of species, one on either side of the organism, and usually in front, and on top . . . What blind luck! (Pun intended)
I think anyone who has done some scuba diving could give you some insight.
Evolutionists only admit dilemmas once they claim to have solved them.
Resolving “Darwin’s Dilemma” is easy. Darwinism, with no material evidence, much less preponderance of evidence, is a fraud and a fake.
Ok class , one more time. A long, long time ago nothing exploded and created everything. We will keep “plugging holes” in this hypothesis until we make ourselves comfortable that surely we will never have to answer to any “higher power” for our misdeeds.
Better give that some critical thought people. Final exam is rapidly approaching.
And why did some apes evolve into man, while other apes remained apes.
I thought the oxygen was due to the cyanobacteria.
“May have?” Since when did “may have” become science? Why didn’t all monkeys and apes evolve? This is just another theory. They haven’t “plugged” anything.
