Here’s an interesting diversion sent to me by my brother, George Bowering. Caution: he’s been known to mess with his own Wikipedia site. It was sent to him by Spider Robinson, who says he got it from John Varley. Quoting Spider Robinson:

“Here’s the broadest possible perspective:

Sent me today by John Varley. Just keep clicking “Okay,” at whatever rate suits you. The further I went, the slower I clicked.

Spider”

Perspective is right. I hope you enjoy it.

Cave Art – More

Among the most popular posts on Green Comet is the Cave Art series, parts One, Two and Three. They make a nice summary of the state of the discipline for anyone with a casual interest. A good way to get a sense of what is out there in the way of cave paintings and rock art in general. On Scienceblogs I found a post by Greg Laden that goes into it in more depth, with emphasis on when and where our human ancestors began to produce it. From his post, How are art and human evolution related:

“Art is almost certainly important and has a place on (the) list of things to consider when wondering about the evolution of our species.” – Greg Laden

Laden does a good job of exploring the subject and makes useful suggestions for further thought and exploration. If you enjoyed the Cave Art series, I recommend furthering your education with his blog post.

Aquatic Ape – The Theory Evolves

Those of you who read my post, Bipedal – The Aquatic Ape Theory, might be interested to learn of this guest blog on Scienceblogs by Marc Verhaegen. He is a much more learned and erudite writer than I, and you will get a much greater depth of information from his post than from my brief outline. Here is a short quotation:

“It is often assumed that Alister Hardy’s and Elaine Morgan’s aquatic ape theory (AAT) suggests that more than 5 Ma (million years ago) there was a semi-aquatic phase in our past (explaining e.g. human fur loss, fatness and upright bipedalism), which was followed by a savanna phase on the African plains. In 2011, AAT proponents published an eBook, ‘Was Man more aquatic in the past?’, which showed a rather different picture of AAT.” – Marc Verhaegen

He was kind enough to comment on my post, and you can see that at the link above. If you are interested in the Aquatic Ape Theory, or in human evolution in general, I encourage you to go and read his Scienceblogs guest blog.
