Bogotá and Popayán

The impressive 'urban sprawl' in Bogota. In the background, the eastern hills. Monserrate enough to look like a white dot, and below the buildings of the "International." In the foreground, the Bogota River. In this picture it is clear the concept of "edge." (This time he wore the airplane window.)

Popayán Puracé the volcano in the background. Here it is also clear the "edge" diffuse between urban and rural (sorry so opaque window.)

Magic "scientific" about the origin of man

Image: http://blogs.rtve.es

Funny see how some juggle paleoanthropologists to human remains found in reservoirs, fit their ideas about the origin of man.
I'll write some posts telling cases quite significant, so that they can understand without going as gall Java Man or Peking Man, things are interpreted and modified to its release, the "scientifically correct" on origin of man seem supported by the findings.
But first make a brief outline to remember what they want to believe, I'll be very brief jump many nuances, in general it is:
1 - There have been several species of men (this is Adolf Hitler was like.)
2 - Their skeletons have gone from being strong and stocky to be tall and graceful.
3 - Their skulls have gone from being "primitive", ie small, large and protruding bulls supraorbital (brow bone), with receding forehead and no chin. A "modern", with larger skulls, more vertical front, bulls supraorbital softer and outgoing chin (chin).
4 - The technique mainly understood as how to carve stone tools has been improving from one species to another.
5 - Aside from some intermediate species, could be summed Case three most important species from earliest to latest: Homo erectus, Homo sapiens and Homo Neanderthalis (that's us).
6 - Do not agree on whether a descendant of the other, or if erectus and Neanderthals are failed attempts.
That said, let's see some trivia:

Lithic industry of the Border Cave.

CASE - 1 - In South Africa, Border Cave, found human remains quite "modern" with plenty of Mousterian lithic type (they call it MSA Middle Stone Age). [1] This is a problem modern humans had a more refined technique for carving flint and quartzite. Solution found to this problem, since very simple: now argue that someone dug in the Mousterian sediments with axes and modern a body buried there. Case solved.
not know if anyone has thought a bit, because if today in the era of communications and globalization, buried a goatherd of Kurdistan with the tools you use daily, and on the other hand buried an elite soldier of a modern army, with all its equipment, and in 1,000 years, a paleoanthropologist at the digs to both, and interprets their findings with the method of comparing utensils, can in some cases to know that both died the same day?, or perhaps say, "the soldier is a much more modern species to which belonged the goatherd?.

CASE - 2 - also in South Africa, was discovered long ago (1932) in Florisbad features a skull with enough "primitive." [2] When it was, was dated with carbon-14 method, and turned out to be 40,000 years. Another problem, how will this man have lived such a "primitive" only 40,000 years ago?, if Africa were already more than set the date for that sapiens colonized the world. How have they solved?, Since very simple, trying to have dated the skull again conveniently, using a tooth and a method called ESR (electron spin resonance) based on microwave radiation, now say the skull is 260,000 years, and already at that time if it fits a man "primitive."
do not know if anyone has been thinking that if the new date is worth, which is made with carbon-14 was wrong in no less than 220,000 years, 550% of the estimated age, can call these methods: absolute dating methods?.
In any case if the carbon-14 method fails at these levels, and in this case they despise, why give credit when it comes to dating carbon-14 fits with your plans?, Or is a genuine method, reliable and scientific, in which case the workaround of the new ESR dating is out of place, or if the method does not work, then be discarded in all cases. How significant this is!.
continue if I can.

The new Australopithecus sediba-a little more "bread and circuses" The new hominid

One of the skulls found in South Africa, the new Australopiothecus sediba. Image: www.rtve.es

just passed ten days of the "new hominid" of Siberia, and we're with a new course ancestor of ours.
All media have been quick to crow good news, in short, have found a few bones of two skeletons of young apes just over a meter tall, which have been dated between 1.8 and 1 '9 million years, the team has studied, dares to place in human evolution from Australopithecus afarensis (Lucy, which we discussed something), and the First Men, in particular the homo habilis. They dare to say that although the bones of the arms and hands indicate that hung from the trees, however, were bipeds, do not tell us how they deduced that the latter is really the most important thing. They also tell us that their brains have about 400 cm3. In these two apes have classified under a new name: Australopithecus sediba.
I will not spend much time because the matter does not deserve, if not for the damage it is doing all this fantasy.
1 - Why is each new skeleton found is a new species, and no one accepts a normal variability within individuals of a species?.
2 - If you are placed as the evolutionary successor of Lucy, why present it as a link in human evolution? If most of paleoanthropologists Lucy placed in another different human lineage, which became Australopithecus robustus and died.
3 - How are so sure they were bipedal?.
4 - Even granting that they were bipedal, something hard to believe without hard evidence, what guarantee is there that a being is a bipedal human ancestor?, Kangaroos and chickens, are bipedal and nobody expected to become human.

5 - Why continue with the mantra that cranial capacity, though at present there are living human beings with brains ranging from 700 to 2,000 cm3 and all of them, their intelligence does not depend on cranial capacity.
6 - Why are flying blind and stunning staff?, Signs unmistakably human as the Laetoli footprints (to cite a single case) more than three million years according to their own dating. How does an evolutionary ancestor of man is to live a million years after their offspring?.
7 - Can you imagine that if they say they have found the skeletons of two gorillas, had not come out in the press or on television, or museums and grants would get millions. Mood
, intoxication continue until they collapse the whole assembly evolution.
