Get over it
If science has shown us anything in the past few decades, it's that for everything that makes humans unique, there a lot more things that we have in common with all other life on earth (especially other mammals). That's why this figure surprises me:
It comes from Science Magazine's recent issue on big questions in science. This article is entitled, "Why Do Humans Have So Few Genes?" It's as if we have gene content envy, or something. Get over it. This isn't a big question. So what if plant genomes are larger than ours.
Science has committed the fallacy of assuming humans are at the top of some evolutionary hierarchy, and that we are the most complex organisms on earth. What is complexity? Can it be measured? Just because we are us does not mean we should assume we have more genes than every other organism on earth. Gene content does not a special creature make.
