Folks at UCLA have created a list of evolutionary winners and losers. They’ve based this list on a species’ ability to diversify over time. At the top of the winners list are birds (with 9,000 species) and mammals (with 5,400 species). Compare that speciation with big fat losers like crocodiles and alligators. Crocs and gators have been evolving for 250 million years and have exactly 23 species to show for it.
One particular loser highlighted in the article is the tuatara, a native to New Zealand.
It looks like a lizard, but they claim it’s more closely related to snakes. Believe what you will. Whatever its family tree, the poor little guys have only diversified to two species. In that same amount of time, we’ve been graced with over 8,000 different species of snakes and lizards. You may be like me and say, “Summin’ ain’t right… how come?” Even those who actually study this stuff for a living are mystified. They are offering a free mosquito teen-repellent device to anyone who can provide an answer.
So like most scientific studies, we’re left still losing sleep over this. That’s why I stick by my guns and say: if you throw “evolution” out the window, you don’t NEED answers. That simple.
In breaking news, here is the latest addition to the list of winners:
Dave, the kitten that survived being shot with a crossbow.
