Evolution Before Our Eyes: How Macaques Learned To Fish


fishing%20macaque.jpg

Scientists in Indonesia recently published a paper documenting their field observations of long-tailed macaques going fishing. Even better, they don’t just reach into the water to grab their own fish—they watch other macaques at work and learn from their techniques. One researcher theorized that “perhaps a couple of generations back, one primate caught a fish and it was subsequently copied.” The scientists suspect that the macaques fish when no other food is available, though they stress that not enough data exists to say for certain.

Okay, so this is cool. It’s not often that we see species adapt to changing conditions at a rate that matches the change. (Recovery from human threat and habitat depletion is rare enough.) Further study of this species could teach us a lot, not only about how macaques adapt to changing conditions, but about how we might adapt as well. Unfortunately, if Congress is any indication of how we’re doing, right now the macaques are coming out ahead.

THANK YOU.

We recently wrapped up the crowdfunding campaign for our ambitious Mother Jones Corruption Project, and it was a smashing success. About 10,364 readers pitched in with donations averaging $45, and together they contributed about $467,374 toward our $500,000 goal.

That's amazing. We still have donations from letters we sent in the mail coming back to us, so we're on pace to hit—if not exceed—that goal. Thank you so much. We'll keep you posted here as the project ramps up, and you can join the hundreds of readers who have alerted us to corruption to dig into.
