  • Crazy evolution movies

    Tue, 2013-06-04 21:32 -- John Hawks

    io9 has a fun list of "The most ludicrous depictions of evolution in science fiction history". Star Trek and Doctor Who come in for the treatment, but how can I not quote the most famous movie evolution of all?

    In the original Charlton Heston movie, three astronauts from 1971 crash land on an unknown planet in what is now the year 3978. The world is ruled by intelligent apes, who have enslaved the mute, primitive humans. At the risk of spoiling one of the most famous forty-year-old twists in movie history, Heston eventually discovers this strange planet is actually Earth. You can probably spot the problem with this story, evolutionarily speaking. There's absolutely no way apes could evolve into intelligent beings in 2006 years.

    To be fair, this scenario is quite consistent with some people's models of human evolution, in which human language and symbolic thinking arise suddenly in a single evolutionary spasm. Of course, those people are just wrong.

    This is going to be very convenient for my students, as I regularly assign this as a paper topic -- pick a famous movie or book depiction of evolution and explain how it is inconsistent with what we know about the evolutionary process.

  • Mankind in the unmaking

    Annalee Newitz gives a worthwhile etymological lesson: "Think twice before using “mankind” to mean “all humanity,” say scholars".

    In modern English, man is used very infrequently as an autohyponym. Possibly that's because it's become too confusing to use "man" — it's hard to know what it means in any given context when we have no word like wæpenmann that refers exclusively to males. But we do have the words "person" and "human" that clearly refer to both sexes, so those have eclipsed "man" when speaking about everyone.

    More at the link. "Mankind" used to be very common in paleoanthropology, most notably in the title of W.W. Howells' Mankind in the Making: The Story of Human Evolution, last published in 1967. Howells cribbed his title from H. G. Wells, whose own Mankind in the Making came out in 1909. It's available for free on the Kindle, or from Project Gutenberg in multiple formats. A name with a long pedigree, that we simply don't use anymore. Star Trek was a few years behind science when it gave up the "no man has gone before".

    I guess that popular culture is usually recycling the science of a decade ago. We've just gotten to where popular culture treatments of human evolution suffer through a volcanic winter, and where Neandertals are extinct. Guess that makes a fertile ground for rewriting over the next decade!

Neandertals

For years, I've worked on their bones. Now I'm working on their genes. Read more about the science studying these ancient people.

Denisova

From a finger bone of an ancient human came the record of a completely unexpected population. My lab is working on the science of the Denisova genome.

Acceleration

The advent of agriculture caused natural selection to speed up greatly in humans. We're uncovering some of the ways that populations have rapidly changed during the last 10,000 years.

Malapa

Just outside Johannesburg, the Malapa site is producing some of the most exciting finds in human evolution. This site is the headquarters of the Malapa Soft Tissue Project.
