Sure, it’s a controversial theory. It is said that people came to America much earlier than we think. How much? No less than a hundred thousand years ago. A recent discovery supports this theory.
The new evidence comes from a collection of mastodon bones found in San Diego. Apparently they were hammered by the first human settlers. The age of the remains is around 130,000 years. The bones were placed on a stone that served as an anvil. There they were hammered with a tool of artificial origin … probably by humans.
Probably but not proven
The authors of the article publish it in the journal Journal of Archaeological Science: Reports. By collecting the material, the archaeologists claim to have ruled out the possibility that the bone dust somehow dispersed and floated on the stones during the excavation work.
«The most economical explanation is that the waste [y el desgaste] They arise through targeted contact with the bone. We think this scenario is the most likely, ”the article reveals.
It is believed, based on archaeological evidence, that the first humans arrived on the American continent 14,000 to 20,000 years ago. The new 130,000-year-old theory was proposed in 2017. More arguments are needed for the scientific society than before.
Controversy
Therefore, many scientists question the artificial origin of the impact on the bones found. For example, the Cerutti Mastodon archaeological site is near a highway under construction, and because of this, it is very likely that the skeletal remains were worn down by machines.
Biologist Gary Haynes said the most likely version is that the construction vehicles buried these stones next to the mastodon bones.
Other reviewers argue that the area was exposed to natural influences long before our ancestors arrived. They could have been trampled, displaced, broken, worn out and realigned by other mammals.
Did people arrive in America much earlier than expected? The new research is not enough to dispel doubts about prehistoric human migration. Nevertheless, it adds to the discussion and motivates the following studies in this area.
We’ll wait until the next test.
