What is your why for the creation?

And what sort of being do you reckon?

how exactly does a posi-trac rear-end on a plymouth work?

It just does

I see shite everyday that I can't explain "why".

I doubt we are capable of understanding the reasons why a divine being created the universe.

It would all be gibberish to us if there was a way for it to try to explain.

Im as shocked as anyone

Oh, ok. Just thought you had considered it and had some interesting or unique ideas on the topic.

The first occurred about 2.2 billion years ago, when an archaea swallowed a bacterium that became the mitochondria

And the archaea's mom was screaming, "Bobby!!! Don't put that thing in your mouth!!!!"

quote:

---

Please explain how DNA of the host organism incorporated the DNA of the assimilated organism and then was able to reproduce with a new genetic code that now included new information..

---

If it works the same way as the mitocondria is believed to work, they replicate within their host while the host replicates and have their own separate DNA

quote:

---

Today, this theory is widely accepted [1]. Mitochondria therefore have their own DNA (mtDNA), circular and double-stranded, closer to a prokaryotic genome than nuclear DNA, with a genetic code slightly different from the universal genetic code found in the nucleus of eukaryotic cells.

quote:

---

Mitochondria are unusual organelles. They act as the power plants of the cell, are surrounded by two membranes, and have their own genome. They also divide independently of the cell in which they reside, meaning mitochondrial replication is not coupled to cell division.

Stupid

The things I learn on TD!

Next up: plants that don't need fertilizer.

Yeah, soybeans and clover, and others. And have been around way longer than humans. I'm surprised that gene splicing hasn't been used to create nitrogen fixing corn, wheat, etc. People in the fertilizer business have worried about that for more than 50 years. Animals and plants are incredibly efficient at manufacturing their own chemicals, in ways that we don't understand yet. Chemicals that normally require high temperatures and pressures are made continuously in the human body. It's probably the next area of expansion for science.

And God so gently placed that little thing right there for a certain reason, and I'm perfectly fine with it.

They aren’t using the nitrogen for energy. They still use solar energy to convert co2 to sugar.

It’s just that nitrogen is a critical part of many biological compounds but only relatively few organisms can introduce it into a biological system.

What it means by “fixing” is being able to take elemental gaseous nitrogen and put it in something bio available. This happens in the soil by bacteria mostly (sometimes in symbiosis with specific plants). Plants use it, and things that eat plants take it up, and so on.
