    Then Evolution Links for reconsideration.....

    Is Life disappearing around us; are we the cause? Or is flourishing beneath us; without us noticing?

    What do you think?

    Mass extinction is a factor in evolution (has been several times). Even if there is a super mass extinction, the insects and microbes will survive to evolve again - maybe into life forms that can survive and thrive in the toxins now present everywhere. They will have a couple billion years to do so (before earth is too hot for life)- just like the microbes had the last time.

    Run (don't walk) away, from New Scientist. It's utter pop-science bullshit. Also, try to eliminate Wikipedia from your life.

    I think you evolve or mutate to escape mass extinction. We might even see a mass extinction soon if the Ebola virus outbreak spreads to the States. Already three Americans, that we know of, have been infected. One has died, stepping off a plane in Nigeria. Imagine the others on the planes in which he traveled?

    You do have those bacteria they found in a boiling sulpher pool in a volcano.

    Most things on line should be steared clear of.

    Go Ebola.. wasn't there an Ebola thing a few years ago also?

    Ebola is a fast disease with symptoms, easy to contain, it shouldnt be that bad. Slow diseases with no symptoms are much harder to deal with.

    My take on evolution is that most people (both scientists and lay people) tend to think it as having telos i.e. purpose and see it as a progression towards ever more complicated forms.
    Which is wrong.
    It is much more accurate to think of it as an optimization algorithm very similar to capitalism. It's a random walk search but a stronger selection makes it look more gradient-like in character.
    Bacteria have very strong purifying selection because of their very high effective population (one bacteria can have very many "off-spring") which gives them enormously efficient genomes with very little non-coding DNA whereas animals have weak selection due low effective population but their mutations allow greater evolutionary leaps. And of course animals co-operate with bacteria, e.g. humans and dogs harbour bacteria that produce proteases that can degrade gluten.

    What's the question? Yes, humans are reducing the species diversity on Earth. Yes, since one very successful evolutionary strategy is to promote an environment that is beneficial to your species and all the species that you depend on fewer species will likely mean weaker ecosystems. That will in turn decrease biological production and increase the risk of systemic breakdown. Think loss of pollinators and collapse of fisheries.
