(ORDO NEWS) — Scientists have said that sea level changes in Micronesia may be indirect evidence that humans appeared much earlier than we thought.
Sea levels in Micronesia, a group of small islands in Oceania, have risen much faster over the past 5,000 years than previously thought, according to a new study.
This is evidenced by the accumulation of mangrove deposits on the islands of Pohnpei and Kosrae.
Scientists have discovered mangrove deposits up to five meters deep in Pohnpei and Kosrae. The only explanation for such deep mangrove deposits could be a permanent rise in sea levels.
Researchers have calculated that over the past 5,700 years, sea levels have risen by about four meters. The most likely reason for this rise is that the islands are sinking.
Scientists speculate that this rise in sea levels obscured the archaeological record of Pohnpei and Kosrae.
Consequently, evidence of earlier settlement may be flooded today. It is possible that humans settled this region of Micronesia much earlier than thought.
