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.

The dilemma is the fact that evolution would appear to be way faster during the Cambrian explosion than Darwin’s theory would allow. They haven’t explained that away - only the minimal evolution before that.

[Did these studies appear suddenly, or slowly?]
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.
[Why did it happen? Darwin is still "worried", but they're working on it.]

[Shift Happens!]
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 [very old duct tape], Ian Dalziel believes what is now North America remained attached [co-dependent] to the supercontinent Gondwanaland until the early Cambrian period, in contrast with current belief, which has the separation occurring earlier.
By “negative stereotypes of Conservatives”, is liberal propaganda actually meant?
Now try to convince a Muslim that Allah did not create the world as the Koran stated. Between US conservatives and Muslims, which one is (far) more likely to slay you?
Global warming??? Seems that’s the default reasoning for everything these days ....
Currently, the scientific community does not recognize "historical" and "observational" as being valid descriptions of the scientific process.
Thanks. That helps.

In other words, the “scientific community” admits that it has thrown away the scientific method.
The scientific method was apparently getting in the way of the agenda.
You called it!! Science no longer requires evidential rigor to the conclusion.
Science and religion only find argument due to the errors of both. These errors are due to the participation of man, who is imperfect.
As creation and its laws becomes better understood, there will be less argument between the two as in the end they both have the same goal.
But since both institutions are run by man, there will always be some error.
Only God is without error, and our attempts to understand God will always be fraught with error due to our imperfection. If religion had achieved the perfect explanation of God’s universal laws, there would only be one religion in the world. Instead, even Christians for example have hundreds of competing sects, including those run by complete charlatans who are followed assiduously by mistaken adherents (Not that Christianity is alone in this).
This is why it is dangerous to put extra men between a soul and God. The more men you put in between yourself and God, the more error will be introduced.
We aren’t expected to reach perfection on this plane, we are charged with only with moving toward it. And there is no requirement that other men are the only way to lead a soul toward God. The communication lines are open directly, use them.
LOL! They just jumped out of the water and waited for lungs to magically appear. Same as if we stayed under water long enough, we would evolve gills. These “professors” should demonstrate. LOL
Real science does. "Political" science seeks to configure evidence to support a desired conclusion.
The invasion of the land was initiated by plants. Next, after millions of years, came the insects. The scorpion fossils show a creature very similar in appearance to the ocean dwelling ancestor as well as the modern scorpion. The Chordata that came later have left many fossils of early amphibians, amphibian like fish and lung fish.
Tyrannical local governments.
Good question
Well they may have monkey blood flowing through their veins, I don’t. So to me it is irrelevant science.
Ok now that solves the mystery. The tectonic plates under the ocean do cause earthquakes, which create tsunamis.
That’s silly we all know that UFO’s landed in Gondwanaland and left new critters.
Just ask any anti Godless person.
