The Dawn of Someone Else

   The Dawn of “Someone
   Else”
Apr 2014 -Dale Alan Bryant
   
    It is April 29, 3012 N. E. (New Era) – exactly 1,000 years to the day later than you had thought. Since that time, just one millennium ago, due to the political uprisings as a result of the Great Final War, which began on the 21st of December 2012, something terribly important has happened; in fact, something frighteningly important...
   
   The Great Final War had caused a separation—a rift in Mankind. Most of its numbers had been unable to reproduce. It was once believed that the three sub-species of humans would eventually intermingle and interbreed to the point of becoming one, homogeneous sub-species or race. But after the war, the races grew slowly and farther apart mentally, spiritually and now physically – a sure sign of the coming speciation. And on this day, one of those races has reached a new dawn - it has become so very different in every way from the others, that it has become a new species in its own right; a new, separate species almost wholly unable to breed with the remainder of its kind...
   On another day in pre-history, this world experienced a similar transformation that would forever change its face – the day Australopithecus afarensis (southern ape of the Afar region) became Homo habilis – “Handy Man” – the first true human. That day will forever be remembered as “The Dawn of Man”. But on this day, April 29, 3012 N. E., the speciation of the human race was nearly complete. Man had become a regular traveler to other, nearby worlds, after almost a thousand years of practice in space travel within the solar system.
    A new dawn has begun for Homo sapiens sapiens (Man, the wise, the wise) - the dawn of someone else: he is Homo sapiens cosmosis (Man, the wise, the star dweller).

   Let the remaining races of men - and their savage ways - come to extinction. Let this new creature – this new inhabitant of planet Earth, prosper and spread to the stars. May he never repeat the mistakes of his ancestors in developing the terrible weaponry of war. Let him be a gentle, reasoning creature who can find peace with his fellows, and for the first time, Peace on Earth – and in the galaxies beyond…


The Dawn of Man


The Dawn of Man
2013 Dale Bryant


If you have not seen the opening, moving, 8-minute scene, titled, "The Dawn of Man", in the movie, "2001: A Space Odyssey", I would implore any thinking person to watch it with thoughtfulness. The scenario is, of course, fictional in that a monolith has been planted at Olduvai Gorge in the Serengeti Plains of Africa, some 3 million years ago, by an extraterrestrial race which somehow enlightens the local inhabitants, Australopithecus afarensis (southern ape of the Afar region) for the first time to tool usage, thereby transforming, at dawn on this particular day, one member of the tribe to Homo habilis - the first Man - Man the toolmaker.
The help from extraterrestrials is, of course, unnecessary; the important thing about this clip is that A. afarensis, at any rate, became H. habilis. I have to admit to both clapping aloud and weeping every time I see it. See it for yourself. Even if you don't subscribe to evolution by means of Natural Selection, it is important for any thoughtful person to watch. The accompanying musical score, "Also Sprach Zarathustra", composed by Richard Strauss, is, by itself, worth the experience.

On the Human Tail (and other rudimentary organs)

On The Human Tail
(and other rudimentary organs)
2012 By Dale Bryant

 The human embryo is indistinguishable from any other vertebrate animal (animals possessing a spinal column, or, notochord with extended extremities, e.g., arms, legs, etc.) This is due to the law of phylogenesis, which covers a period of many millions of years of vertebrate evolutionary development. Another law, the law of ontogenesis, explains the brief period of development from conception to birth.
 
   The embryos of all vertebrates, including us, exhibit our entire evolutionary development, starting out with the fishes, extending to the amphibious vertebrates, then on to reptiles and eventually birds and mammals. Our entire developmental sequence over millions of years is apparent. The human, dog, fish, chimpanzee, tortoise, whale and all other vertebrate embryos have gills, legs (yes, even whales), and tails as well as other rudimentary organs which, in the case of the mammals have been abbreviated or aborted. Humans still possess a short tail, consisting of four to five fused vertebrae at the end of the spinal column, called the coccyx (kok-six).

   This, of course, suggests that all extant life forms (99% of all life that has ever existed is now extinct), developed or evolved from a common ancestor in the remote past and that Man was not instantly placed here on this planet, in his present, "unchanging" form by a Creator with a definite plan outside of mechanical causes. This is a very sensitive issue for those who subscribe to a dualistic approach to creation, and those averse to changing previously accepted thinking. I do feel for you as I was once one of you, but then I transferred my interests from professional astronomy to paleoprimatology and saw for the first time the very obvious.
 
  I can recommend a good book by Ersnt August Haekel titled “The History of Creation” available free online at Google Books. Do it!

See ya!

On Natural Selection

 On Natural Selection
 2012 by Dale Bryant
 
    Still need proof of Darwin’s theory? Read on. The fact that new species develop according to adaptation and inheritance is known as the Theory of Selection, whether it be naturally or artificially induced. It was proposed by naturalist Charles Darwin in the mid-1800’s and is known as “Darwinism”. It’s a common misconception that Darwin was the originator of the Theory of Evolution. Actually, the idea of the formation of new species by descent was proposed by Jean-Baptiste Lamarck 50 years earlier and is called “Lamarckism”. It was even suspected by Aristotle. Darwin only explained the descent of organisms by means of Natural Selection, in his book, “On the Origin of Species by Means of Natural Selection”, and only used the term 'evolution' once in this work. In fact, this theory was independently developed by Alfred Wallace at about the same time. Darwin actually put off publishing the results from his observations in his book for twenty-one years, until he was convinced that there was no other explanation possible.
    The fact that breeders of dogs, cats, horses, tomatoes or strawberries breed their stock to achieve some desired result – whether it be a tastier strawberry, a smaller dog, a faster race horse, etc., is the proof. You might think that it is "only a theory", but that implies that theories don't provide proof. All scientific ideas and natural laws are backed by theories. The Theory of Selection is a mathematical constant: that is, the relationship of available space for an organism to exist and the number of organisms competing for that space. Obviously, some organisms thrive while most others die off, an invariable consequence of the mechanism of the 'Struggle for Existence', a.k.a. 'Survival of the Fittest'. The fittest, according to genetic adaptation and inheritance, tend towards survival while the least fit tend towards extinction. Very sensible, is it not? In fact, the seemingly endless variety of organisms, still very much in transitional states today, as can be seen in the rudimentary, atrophied hind legs of whales and dolphins, or the now defunct internal organs of many species, including the appendix of man--can only be explained by the Theory of Selection; otherwise it is left to the unfathomable realm of miracles.
    The Theory of Selection is a self-evident law of nature and requires no further proof any more than you require further proof that more than one breed of dog exists. The fact that people from around the world look differently, or that there are German Shepherds, Chihuahua’s, Beagles and Irish Setters, is all the proof of the Theory of Selection you should require. These breeds, or, sub-species, were intentionally created – bred from a common ancestor of the genus' Canis (dog) and Lupus (wolf). In fact, some breeds of dog are so distantly related that they cannot reproduce together – although they belong to the same genus, they have, through Artificial Selection (selective breeding induced by man) become distinctly separate species. Selection induced by nature is called 'natural selection' and works in exactly the same way, only much more slowly.
 Darwin also provided proof of another weighty philosophical question when he explained natural selection; that is, the question of how arrangements serving a purpose can arise mechanically without causes acting for a purpose. If you’re at all familiar with some simple math and statistics, you’ll see the logic in it immediately. If you still require proof at this point, you either don’t thoroughly understand the theory or are not sufficiently acquainted with the fundamentals of biology; and if that is the case, you really should familiarize yourself with those two components before coming to any conclusions on the subject.
    Oh, just one more thing... I realize this little essay of mine smacks of sacrilege but that is not my motive at all. Like most of my writings, it was only meant to spark a little controversy and bring your blood to near boiling (contrary to popular belief, I like to have a little fun too!) But, unfortunately, like the rest of us, I was not present at The Creation (though I feel I could have given the Creator a few pointers) but, alas, the truth is, I have an agreement with God--I don’t tell Him how to design universes--and He doesn’t tell me how to interpret the obvious.
    I need to stop here – hell, I’m in deep enough as it is!... would it help if I said I didn’t mean it (yes, I did), and I won’t ever do it again (yes, I will)--I promise (no, I don’t!)....
   I’ll end with my favorite quotation on the obvious, as it applies to nature: “If it looks like a duck, walks like a duck and quacks like a duck – it’s a duck.”




On Extraterrestrial Evolution

On Extraterrestrial Evolution
2011 by Dale Bryant

Virtually all reports of contact with, or sightings of, alleged creatures of extraterrestrial origin, describe these beings as humanoid, i.e., possessing large heads with two eyes, a thorax or torso, with two pair of extremities or limbs, the lower pair functioning as legs, as these beings primary mode of locomotion happens to be bipedal. This is all very interesting; the form that a body takes is dictated by its geological surroundings - including and especially available food sources, atmospheric composition, air temperature and pressure, amount of received sunlight, natural enemies - even variations in the gravitational pull of the host planet itself according to geographic location. All of these factors are highly variable at any given locale and conspire to shape our bodies - even as finely as the cusps on our molar and pre-molar teeth, to accommodate the foods we will eat as we begin a solid food diet. This is why humans look the way they do and why gazelles, rabbits, fish and spiders look the way they do, not to mention all the different general body types involved (vertebrates, invertebrates, arthropods (those with articulated limbs or segmented bodies), etc.)

The possibility that intelligent extraterrestrial beings would be humanoid in form is barely even remotely possible. The evolutionary chain of events, through the process of natural selection, which includes physical and mental adaptation and inheritance of favorable characteristics, that led to H. sapiens, was a very specific one and occurred only once on this planet; its recurrence on some other world is unthinkable; any life forms on another planet would likely be something other than humanoid and not even remotely resemble any form of life on Earth.
 The humanoid form is based on an anthropoid body plan, one of the many body plans of earthly fauna. The anthropoid cranium positions two eyes, anteriorly, or at the front of the skull. This arrangement provides binocular, or stereoscopic vision to the possessor, which is very sensitive to the movement of its prey, indicating a predatory carnivorous ancestry. Our earliest mammalian ancestors were herbivorous, with eyes positioned at the sides of the head, providing a more panoramic view much less sensitive to movement. The anthropoid body plan also includes four limbs in two pairs--the upper pair was used by our last common ancestor for swinging from branch to branch among the trees and even included hands for that form of locomotion known as brachiation. The bottom pair of limbs became important in our upright, erect posture for moving across large swaths of ground after we transitioned from an arboreal existence to the necessary mode of locomotion adapted for the savanna, bipedalism. To expect that beings from another world would have taken essentially the same evolutionary pathway as human beings is akin to expecting that they speak English too! Given any similarities, it would be even more likely that these alleged humanoid forms are actually us--from a very distant future and evolutionary development--come back to visit ourselves, via some unlikely, but plausible, manipulation of the fourth dimension--time.
 The scientists who study the possibilities of life on other planets are called Astrobiologists and Exobiologists. What do you think an extraterrestrial intelligence, should they actually exist, might look like?
