It has long puzzled scientists why, after 3 billion years of nothing more complex than algae, complex animals suddenly started to appear on Earth. Now, a team of researchers has put forward some of the strongest evidence yet to support the hypothesis that high levels of oxygen in the oceans were crucial for the emergence of skeletal animals 550 million years ago.
The new study is the first to distinguish between bodies of water with low and high levels of oxygen. It shows that poorly oxygenated waters did not support the complex life that evolved immediately prior to the Cambrian period, suggesting the presence of oxygen was a key factor in the appearance of these animals.
'Although there is geochemical evidence for a rise in oxygen in the oceans around the time of the appearance of more complex animals, it has been really difficult to prove a causal link. By teasing apart waters with high and low levels of oxygen, and demonstrating that early skeletal animals were restricted to well-oxygenated waters, we have provided strong evidence that the availability of oxygen was a key requirement for the development of these animals. However, these well-oxygenated environments may have been in short supply, limiting habitat space in the ocean for the earliest animals.'

Amazing that seemingly intelligent people would believe that all of this was just random chance.

Are you saying that time travelers went back and did some biological engineering?
Actually, the only people I see bringing up random chance are they hecklers from the sidelines, not the people doing the methodical hard work.
I saw a documentary on animals that lived during the Ice Age. They were incredibly, amazingly huge. I suppose that all those huge animals passing gas caused the climate to heat up and melt back those ice sheets.
“Are you saying that time travelers went back and did some biological engineering?”
Well, technically God is a time traveler, so sure, if it helps for you to think of it like that.
“Actually, the only people I see bringing up random chance are they hecklers from the sidelines, not the people doing the methodical hard work.”
Well, you can’t expect evolutionists to be eager to advertise the fatal weakness that their entire theory rests upon.
Fungus (there’s only one of you right?);
You recognize that Quantum science espouses the concept that the is no such thing as chance( randomness) right?
Every lead points directly to the hand of God....
Please elaborate. There are millions of fungi.
Personally, I prefer to say that I don’t know what might be in a room that I’ve never seen inside of. How anyone could say otherwise strikes me as arrogance.
We are a tiny spec in the universe. I think it’s very unlikely that the son of God was born on the earth. Let’s not be so self-centered and arrogant!
Thanks for agreeing with the statement:

How do you know that?
If the life form is carbon based and the progressive planet geology is similar to earth, then you probably would be correct in saying than life would expand beyond the relatively simple single cell later in the geological history of the planet. Other life form bases require other conditions and may come to dominance earlier.
Every ‘form’ of life is the product of it’s environment. Change the environment, that ‘form’ will change.

Oxygen is essential to carbon based life and, ar the same time, highly reactive. The production of free oxygen by algae was consumed by iron in the oceans for millennia. Free oxygen allowed the expansion of carbon based life and could only take place after the formation of the banded iron deposits. This study, looks at the expansion of shallow ocean environments friendly to our life form.
Of course there are a multitude of other conditions that had to be met like relatively stable temperature and lower levels of volcanic and meteor violence.
And as life arises naturally, would not the immortal soul also naturally come into being as life evolves closer to the creator's image? What is 20 billion years to the Infinite, the Alpha and the Omega? Evolution and scientific discoveries do not diminish God, the fault is in us when our weaknesses lead us to feel small and unimportant in the vastness and age of the universe and the further revelation of God's greatness.
There are many accounts of how our greatest scientist become firm believers in a creator the more their research reveals to them and the more they realize how little they know and how awe-inspiring the universe is.
The available evidence seems to indicate that abiogenesis occurred once, mitochondria occurred once, and chloroplasts occurred once.
We also know that if there is another evolutionary pathway to complex life it didn’t occur here on Earth. We only see the one. What we observe in evolutionary biology astounds me, much the same as the observations that led to quantum theory.
Random chance had some impact on what you did today. When random chance is confined to exactly what mutations an organism has in its DNA that is the major function controlled by chance alone. As to the survival of that mutation and it’s being passed along to future generation, the role of chance become very low in comparison to the advantage or disadvantage that mutation confers on its organism. If it works, it is retained and passed along. If not, it is discarded. That reflects the limited role of chance — pretty small.
Because, any being that would fit the definition of “God” exists independently of His own creation, and that creation includes time.
“That reflects the limited role of chance pretty small.”
I think you’re seriously underestimating what chance is accomplishing in the theory. Without the millions or billions of random mutations to provide new versions of genes, there is no development in the organism. Natural selection merely selects the most “fit” variations, but it is the random chance that provides the raw material, the variations themselves.
There’s also random chance involved in the conditions those variations will encounter, which are key to whether they will be selected or not. So there is random chance dictating both parts of the process. Once you abandon any intelligent intervention in the process, what is left but random chance?
