Scientists project that nearly 20,000 species across the globe are at a high risk of extinction, and that within the next 300 years, some 75 percent of all mammals could completely disappear from Earth. Experts say that we are in the middle of the sixth mass extinction of life on earth. And what distinguishes it from the previous five extinctions is that it is being caused by humans.
This hour of Radiolab, a look at race. When the human genome was first fully mapped in 2000, Bill Clinton, Craig Venter, and Francis Collins took the stage and pronounced that "The concept of race has no genetic or scientific basis." Great words spoken with great intentions. But what do they really mean, and where do they leave us? Our genes are nearly all the same, but that hasn't made race meaningless, or wiped out our evolving conversation about it.
