Going off the well-beaten path (you know which one I mean), I came across a rather intriguing article and thought some of you might find it interesting. (And then again, maybe not. 🥱)

In any event, the link below will take you to an article entitled “20 Space Myths Busted!” Just to whet your interest, a couple of the “myths” are:

  • Black holes suck
  • The sun is yellow
  • Light isn’t affected by gravity
  • Saturn is the only ringed planet in the solar system

-SPACE MYTHS BUSTED-

Now I realize not everyone visiting this blog will feel this is a cannot-pass-this-up! article, but for those who do find it fascinating, I hope you’ll share your thoughts.

(And you have to admit, it is most definitely a diversion to the overly discussed topic of the day!)

Homo Sapiens Dominance?

The following is a brief of an article recently published in the NewScientist magazine (I only get the newsletter). I’m sharing it primarily due to the final paragraph (highlighted). 

HUMANS today are uniquely alone. For the majority of the existence of Homo sapiens, we shared the planet with many other types of human. At the time when our lineage first evolved in Africa some 300,000 years ago, there were at least five others. And if you were going to place a bet on which of those would outlast all the rest, you might not have put your money on us.

The odds would have seemed more favourable for the Neanderthals, who had already adapted to live in colder conditions and expanded to inhabit much of Eurasia. Or Homo erectus, who had made a success of living in south-east Asia. By contrast, our direct Homo sapiens ancestors were the new kids on the block, and wouldn’t successfully settle outside of Africa until more than 200,000 years later. Yet, by 40,000 years ago, or possibly a bit more recently, we were the only humans left standing. Why?

Many explanations have been put forward: brainpower, language or just luck. Now, a new idea is building momentum to explain our dominance. Ironically, it may be some of our seemingly deepest vulnerabilities – being dependent on others, feeling compassion and experiencing empathy – that could have given us the edge.

While I would LIKE to believe this “new idea” related to the dominance of Homo Sapiens, it’s difficult to see these suggested “vulnerabilities” in much of today’s modern societies.

Male seahorses could talk! stockvault-seahorse-sketch108487

NewScientist.com reports that male seahorses form close, monogamous relationships with the female … and it is the MALE that carries the pregnancy from shortly after fertilization all the way to birth!

Were this true of humans, one can’t help but wonder if there would be a VERY marked difference in the way abortion is viewed by some …
