Discussion Overview

The discussion centers around the possibility of human occupation in Antarctica during prehistoric times and whether there are remnants of stone structures beneath the ice. Participants explore the geological history of the continent and its potential to support life in the past.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Some participants propose that Antarctica may have been occupied by humans, suggesting the existence of stone structures similar to those found in other regions.
  • Others argue that Antarctica has been largely iced over for millions of years, making human occupation highly unlikely.
  • A participant questions whether the continent's geographical position could have supported life as recently as 15,000 years ago, suggesting that it may have been warmer and more hospitable in the past.
  • Another participant provides evidence that the East Antarctic Ice Sheet is approximately 500,000 to 1,000,000 years old, while the West Antarctic Ice Sheet may have been ice-free more recently, indicating potential past conditions that could have allowed for life.
  • There is mention of fossils found in soil samples beneath the ice, which could suggest that the ice sheet has collapsed before, raising questions about the historical climate of Antarctica.
  • One participant emphasizes that while Antarctica supports life today, it has a rich fossil record indicating that it was once home to various forms of life, although this occurred much longer than 15,000 years ago.

Areas of Agreement / Disagreement

Participants express differing views on the potential for human occupation in Antarctica, with some asserting it is unlikely due to the long history of ice coverage, while others suggest that geographical and climatic changes could have made it possible. The discussion remains unresolved with multiple competing views.

Contextual Notes

There are limitations regarding the assumptions about the timeline of ice coverage and the geographical positioning of Antarctica, as well as the implications of fossil evidence on the continent's past climate and habitability.

Does anyone think there is a possibility of the Antarctic continent
having once been occupied by mankind and that beneath the ice are stone structures similar to what is seen in Central and south America and in the middle east?

Almost certainly not.

There has been life on Antarctica but you have to go back many, many millions of years (long before anything resembling man appeared) to find it.
 
Thanks Phil
Are you implying that
1. The Antarctic continent has been iced up for millions of years
2. That the Antarctic continent was geographically in a different position to have actually supported life of any kind.

personally I like number 2.

The Antartic continent may have been at a different geographical position as close as 15000 (fifteen Thousand) years.
 
The Antarctic continent has been iced up for millions of years

Well let's say that the East Antarctic Ice sheet is probably about 500,000 - 1,000,000 years old, dated at Vostok. The west Antarctic Ice Sheet has not been dated accurately but it seems to have been ice free very recently:

The debate over whether the ice sheet is at risk hinges partly on its past history. Scherer has found the first direct evidence that the ice sheet has collapsed before. In soil samples recovered from nearly two-thirds of a mile below the ice, he found fossils of tiny marine plants called diatoms. Some of the fossils were less than 650,000 years old, and Scherer says they were deposited the last time an open ocean, not ice, covered this part of Antarctica.

"Until now, there has been no direct evidence that it's happened before," says Scherer. Although he couldn't precisely determine the age of the diatoms, he suggests that they formed 400,000 years ago, a time when geologists believe that sea-surface temperatures were about 9 to 12 degrees warmer than today and sea levels possibly 65 feet higher. If he's right, the diatoms mark the ice sheet's last collapse.

So I would not exclude it completely that hominids have strolled around in the past.

Antartica was certainly at a different position in the past to support more warm suited life (it actually supports life of many kinds now, btw), there pleny of fossils to prove that, in addition to a mountain of other evidence. But it happened much longer than 15,000 years ago.
