If Evolution Is In Progress, Why Fight Extinction? @PaulA.Clayton Doesn't natural selection assume that a local optimum (emerging species) is superior to a more global optimum (aka invasive species)? If it were only about preserving outdated ideas we would merely sequence their genes and let the endangered species die--that would be much cheaper in many cases. You mention "artificially increased mixing," but you ignore the fact that for much of early history the world is believed to have been a single continent, which means "mixing" back then was naturally easier than today and likely comparable to human induced mixing of the present. |

If Evolution Is In Progress, Why Fight Extinction? @Armatus How does evolution pre-humans deal with the issue of invasive species? Aren't invasive species the "fittest" creatures that evolution through natural selection favours? Doesn't survival of the fittest imply an expense to the less fit aka non-invasive or native species? Why should humans interfere with invasive species? The fittest survive right? Genetic engineering would deserve its own question. |

If Evolution Is In Progress, Why Fight Extinction? @Armatus Couldn't the same argument be made for invasive species? |

Are there any plants that fix their own nitrogen? There soon may be: cbgp.upm.es/en/noticias/NFIX_LRubio_BMGF.html |

Where is the line between Anaerobic and Aerobic? The Kreb cycle can indeed take place. You speak of the final electron acceptor being different than oxygen, but for what process? Surely you are referring to the electron transport chain? That would power the regeneration of NAD+ and FAD+. Thus anaerobic respiration includes the Kreb and the ETC. |

Where is the line between Anaerobic and Aerobic? A friend of mine checked 8 different introductory biology textbooks: 6 of them described respiration as using oxygen. However 2 of them did not specifically state oxygen as the terminal electron acceptor, which I am convinced is technically correct. Nitrogen as a terminal electron acceptor is an exception and not the rule, which is why it is so often overlooked in textbooks. |

Is There An Initiative To Sequence The Genomes Of Critically Endangered Species? It seems like genomes are more valuable than spaceships. |
