Live Streaming: Great Adventure in the Wilderness

In the swamp, mosquitoes danced, and a five-meter long bay crocodile was firmly bound at the snout, its vertical pupils gleaming with ferocity. At that moment, a young man cover in mud was straddling it, and he was very modest in the face of audience's praise. "I'm Bi Fang, a professional explorer. I have trekked atop the roof of the world and traversed through the Valley of Death, and I've even challenged the mysterious Amazon. Even the National Geographic has named me the world's premier survival expert, the king of the wild at the top of the food chain, but trust me, that's all an overstatement..." Under the crimson clouds, Bi Fang silently tightened the rope in his hand and, seeing that the bay crocodile beneath him had finally stopped struggling, he pulled out the Hunting Knife and killed it with a single strike to the underside of its jaw. "Today is the second day of survival. I thought I would have to endure another hungry night, but now it seems, dinner has taken care of itself."

Chapter 840: Return to the Country

Regarding the origin of mitochondria, Bi Fang knew of a very interesting hypothesis.

Mitochondria used to be bacterial organelles in eukaryotic cells and have an endosymbiotic relationship with humans.

Simply put, a long, long time ago, mitochondria were independent organisms that, by chance, combined with humans and eventually became part of the human body.

To this day, they still maintain a certain degree of "independence."

Evidence of this is that mitochondria and the human genome are entirely different matters.

The mitochondrial genome is 16,569 in length, encoding 37 genes, mainly related to the respiratory chain.

The human nuclear genome is 3 billion in length, encoding 20-30 thousand genes, including all content.

There is no homology between the two sequences.

And the genomes of other tissues within the human body are all from the human nuclear genome.
