The Strange Tale of a New Species of Lizard
In the 1960s, scientists noticed that some whiptail lizard species had a strange genetic makeup. They have two copies of each chromosome, just as we do, but each copy is very different from its counterpart. The genes look as if they come from different species. Perhaps stranger, many species produce no males. The eggs of the females hatch healthy female clones, a process known as parthenogenesis. Normally, unfertilized animal eggs have only one set of chromosomes. The second set is derived from a male’s sperm following fertilization. But parthenogenic female whiptail lizards can duplicate the chromosomes in their offspring without males. These findings led scientists to a hypothesis for how these strange species came about: Sometimes individuals from two different species of whiptail lizards interbreed, and their hybrid offspring carry two different sets of chromosomes.
Were the First Artists Mostly Women?
I find the counter argument pretty interesting:
For adults, caves would have been dangerous and uninteresting, but young boys would have explored them for adventure, said Guthrie, an emeritus professor at the University of Alaska, Fairbanks. “They drew what was on their mind, which is mainly two things: naked women and large, frightening mammals.”
That makes sense to me. Put the raw data makes sense too. This study does seem to end the idea that these were done by the hunters.
Moore’s Law and the Origin of Life
As life has evolved, its complexity has increased exponentially, just like Moore’s law. Now geneticists have extrapolated this trend backwards and found that by this measure, life is older than the Earth itself.
Queue the creationists claiming this as proof of divine intervention.
