Well of course we're still evolving

but scientists are realising we're evolving much quicker than pre-agrarian humans--partly in response to diseases that hit large groups of people who are living in close quarters. But pale skin and blue eyes are relatively recent mutations, for example.

Study finds humans still evolving, and quickly

Culture Speeds Up Human Evolution

Also on the scientific front, Voyager 2 has discovered a dent in our solar system due to magnetic forces.

Voyager 2 finds solar system's shape is 'dented'

I was 10 years old when the Voyager probes were launched, along with their Golden Records. An excerpt from the Voyager 1 greeting by Jimmy Carter (given in the Wikipedia article) goes like this:

We cast this message into the cosmos… Of the 200 billion stars in the Milky Way galaxy, some — perhaps many — may have inhabited planets and space faring civilizations. If one such civilization intercepts Voyager and can understand these recorded contents, here is our message: We are trying to survive our time so we may live into yours. We hope some day, having solved the problems we face, to join a community of Galactic Civilizations. This record represents our hope and our determination and our goodwill in a vast and awesome universe.


The 70s were in some ways a very hopeful time, weren't they?
