I have seen this before, but it still touches me. Sagan was a great communicator of things that I adore. I was fortunate to meet him once, but it was only briefly after a presentation that he made at an annual AAAS meeting. I also was fortunate to pass Margaret Mead in the hallway with an entourage of her students.
Awesome! Makes one feel very insignificant in the grand scheme of things...does reiterate the fact humans are the worst blight to ever hit this beautiful planet....thanks for sharing, my friend...
Our human genome is full of viruses similar to HIV-1. These have played an important role in human evolution and still play an important role in human embryology and day-to-day chemistry. Just how important are they to our evolution past and future?
