00:00You surely talked about the Chipchas in the school.
00:03Well, today we are going to explain why it is time to forget what the professor said.
00:08Look quickly this map.
00:10The Chipchas was not a small group.
00:12The scientists who have studied it today know that the Chipchas family
00:16extended from Honduras to the Magdalena River.
00:20It's a lot of land.
00:21And not only that.
00:22What they have documented changes what they probably told them about Colombia once.
00:27It was a simple corridor before the European invasion started.
00:32No, ladies and gentlemen.
00:34Here there was a large population organized in a very complex way.
00:39I told you from Camilo Niño Vargas,
00:41Doctor in Antropology Social and Etnology at the University of the Andes,
00:45who studied the Chipchas very well.
00:48But I tell you this to tell you another very fascinating thing.
00:52Some days ago, a group of scientists,
00:54led by researchers from the University of the National University,
00:57found a piece more in that big head that is our past.
01:01They found the pistas of a group of human beings
01:05that was close to Bogotá for 6.000 years ago,
01:08but that disappeared without leaving any traces.
01:12How so?
01:13Look at that.
01:14This people, Superpila,
01:15extracted DNA of humans from thousands of years ago,
01:19that they found in municipalities like Madrid or Nemocono,
01:22like these, that they found in the 90s.
01:25And they can't imagine how difficult it is to extract DNA from a bone or a bone
01:30that had been buried 2.000 or 6.000 years old.
01:33The case is that after reconstructing the genome of 21 people
01:37and comparing it with the ancient DNA that other scientists have analyzed in more countries in South America,
01:44observed that they did not coincide in anything.
01:47It is to say, they found a new lineage.
01:50It was a population that was here in Bogotá and disappeared without leaving rastro.
01:55How and why they disappeared?
01:57These are already hypotheses.
01:59But for those who have studied our ancestors,
02:01like the professor José Vicente Rodríguez,
02:04of the Department of Antropology of the National University,
02:06this population could disappear by some environmental catastrophe,
02:11like the eruption of the volcano Cerro Machín,
02:14to 150 km from Bogotá.
02:16Another thing, this work that uned investigators from Colombia
02:20with professors from Germany has another fascinating point.
02:23It is the first time they managed to reconstruct the genomes
02:27of those who were in our country for thousands of years.
02:31That means that the population of South America was very dynamic before the Spanish arrived.
02:38The chipchas colonized a great diversity of entornos during the centuries.
02:43Today, fortunately, there are descendants who speak more than a dozen of their languages.
02:48But if you want to know more about this fascinating story,
02:52read it in the section of Ciencias del Espectador,
02:55that here we are taking place on the scientific period.
