    A Selection Strategy

    A Selection Strategy

    If you were somehow in control of repopulating and regenerating an area that had essentially been wiped clean of life, how would you do it?  With limited resources at your disposal would you decide to throw all your effort into producing as many offspring as possible, as quickly as possible?  Or would you take a different tasctic and produce a one or two offspring, protecting and nourishing them until they can take care of themselves?
    Both strategies might work.  And that’s what nature had to do.  It had two strategies to chose from.  They are known as the r and K selection estrategies.

    A Bit of Astrobiology

    A Bit of Astrobiology

    How do we find life in a galaxy, or galaxies, far far away while sitting here on Earth? It’s not just by looking through telescopes or sending probes.  Those will tell us a few things, but not everything.  We need a multi-disciplinary approach.  One that combines astronomy, biology, oceonography and chemistry - and that’s just to name a few.
    Enter Astrobiology.

    Carrion My Wayward Plant

    Carrion My Wayward Plant

    A friend of mine recently poased a question on his podcast about carrion plants.  If you don't know what one is, the carrion plant emits an odor that is very similar to rotting flesh.This odor attracts flies which serve to pollinate the flower.  The question posed on my friend’s show was how?  How does the plant know to do this?

    Artificial Selection

    Artificial Selection

    We don’t know why dogs became man’s best friend, but we have some ideas.  And those ideas take us back anywhere from 10,000 to 40,000 years ago.They are perhaps the perfect visual example when it comes to witnessing the power of the gene pool and how a selection process, whether natural or artificial, can affect it.

    Cro-Magnon

    Cro-Magnon

    As a kid I was fascinated by the idea of cavemen.  Of course, all I had to go on were a few porrply produced movies that depicted cavemen battling dinosaurs, which of course never happened.  I even owned an early plastic model of a Cro-Magnon man and woman.  To me the Cro-Magnon were indistinguishable from the Neanderthals.  As far as I knew they both lived in caves, wore skins of the animals they slaughtered and fought with spears.  
    Spoiler alert - we really don’t refer to them as Cro-Magnon anymore.
