The first sex on Earth looked like square dancing — if fish could square dance, of course.
That is the finding of a new study of 385-million-year-old fossils that reveal that the oldest jawed fish on Earth were the first to reproduce by copulation. Later fish would revert to spawning — releasing eggs and sperm into the water to meet — but some have since re-evolved the ability to have coupled-up sex.
The oldest known sex act took place when tiny fish called Microbrachius hooked their jointed arms side by side and linked bony genital claspers with bony genital plates to transfer sperm from male to female.
…and NOT by media hype
1. (tie) cancer & heart disease
2. traffic accidents
4. climate change
5. War in the Balkans
6. The flu
Note that ISIS and Ebola are not yet mentioned, yet the media and politicians hype them above all others.
Your health ranks well above the hyped stories, but the ‘fear factor’ puts us all on edge. In fact, household accidents ranks higher than Ebola.
What does this show us? The two largest cable news networks, CNN and FOX enjoy scaring the hell out of us and it sells advertising time. It’s all about the money for CNN and it’s about feeding the base for Fox.
A pilot looking down at her plane controls and realizing magnetic north is hovering somewhere over Antarctica may sound like a scene from a science-fiction movie, but new research suggests the idea isn’t so far-fetched in the relatively near future.
A magnetic field shift is old news. Around 800,000 years ago, magnetic north hovered over Antarctica and reindeer lived in magnetic south. The poles have flipped several times throughout Earth’s history. Scientists have estimated that a flip cycle starts with the magnetic field weakening over the span of a few thousand years, then the poles flip and the field springs back up to full strength again. However, a new study shows that the last time the Earth’s poles flipped, it only took 100 years for the reversal to happen.
The Earth’s magnetic field is in a weakening stage right now. Data collected this summer by a European Space Agency (ESA) satellite suggests the field is weakening 10 times faster than scientists originally thought. They predicted a flip could come within the next couple thousand years. It turns out that might be a very liberal estimate, scientists now say.
I’ve been in the trenches of Social Media where keeping my intellectual capacity up to par has been seriously challenged, but I thought I would share this with you:
I’m not sure if this is serious stupidity or rampant ignorance since pretty much everybody knows it is the US CONSTITUTION that begins “We the people..”
Well, everybody except this idiot.
The Phrase “we the people” is totally absent from the Declaration of Independence.
Which would be something this person would know if he actually read either document, which he obviously hasn’t.
Neither has he understood either one for their historic and legal significance. And I am not patient enough to try to educate this person since he is a lost cause for any intellectual pursuit.
I would be pretty sure that things like ablative absolutes would seriously go well beyond this person’s intellectual capacity.
Again, why I don’t bother with the average gun loon. This clown is pretty typical for the intellectual level of a gunloon.
Of course, Gunloons will more than eagerly foist their ignorance upon one.
Ignorance isn’t bliss: it’s really fucking annoying.
Yes, they needed it back then too. A number of Medieval latrines — still filled with their original contents — have been unearthed in Denmark, according to archaeologists working in one of the largest urban archaeological excavations in Danish history. Well, imagine that find! Described as being in “excellent condition,” the human excrement was found in wooden barrels originally used to transport goods and store fish. Later converted into latrines, the barrels were unearthed in the center of the medieval town of Odense, the birthplace of fairy tale writer Hans Christian Andersen. “We are talking of 700-year-old latrines. And yes, they still smell bad,” Maria Elisabeth Lauridsen, the archaeologist in charge of the excavation, told Discovery News.
The reason Northern European countries with more regressive taxes achieve such high levels of labor market equality, despite less progressive tax systems, is that they spend money on increasing the skills and earning power of low-end wage earners. Countries with the lowest levels of inequality have learned that policies to cultivate skills for all workers and to achieve full employment policies can accelerate economic growth while also reducing inequality. Large investments in human capital reduce societal conflicts over the distribution of resources, even while expanding the economic pie.
