    Carbon nanotube vs carbon nanofiber

    I understand what a carbon nanotube is. I have some experience with geodesic domes and the way those shapes can be changed. I keep hearing more and more about carbon nanofibers but I've never seen it explained. Is a carbon nanofiber a bundle of nanotubes, chains of carbon particles or something...

    Maximum Sustainable Earth Population

    Well, yes, it does take a long time for these resources to form, but it doesn't take that long to recycle them. Using mulching and composting we can create new topsoil. We don't have to wait for a car to rust away to iron ore, then re-refine it. We can just recycle the metal and use it over and...

    That's a new one on me.

    Most recent common ancestor and Mitochondrial Eve

    There are no other, known mitochondrial lines in homo sapiens despite extensive, world-wide testing. It may be that there is some very isolated group in Africa who belong to a different mitochondrial line, but the odds are pretty slim.

    Most recent common ancestor and Mitochondrial Eve

    I'm not sure I'm understanding your post. With mitochondrial DNA (mtDNA) there is no recombination. The mother passes mtDNA to her children intact (excluding mutations). Fathers don't pass on mtDNA at all.

    Most recent common ancestor and Mitochondrial Eve

    There was also a Y-chromosomal Adam, who lived about 50,000 to 80,000 years later than Mitochondrial Eve. All male humans inherited the "Y" chromosome from him.

    Most recent common ancestor and Mitochondrial Eve

    Mitochondria is not passed through males, only females. Sperm contributes no mitochondria, only eggs do. Every person on Earth can be traced directly to Mitochondrial Eve. There are no other surviving mitochondrial lines. She is the most recent female common ancestor.
