Scientists May Have Found the Oldest Animal on Earth Hidden in A Remote Mountain Rocks

Key Points:
- Tiny structures found in ancient Canadian rocks, dating back nearly 890 million years, may represent the oldest traces of animal life, potentially pushing back the timeline for animal appearance by 350 million years.
- The fossils, discovered in the Northwest Territories by geologist Elizabeth Turner, resemble the internal skeletons of modern sponges and were preserved in a prehistoric marine environment.
- Experts note that these findings align with molecular clock studies suggesting sponges could have appeared close to 1 billion years ago, filling a significant gap in the fossil record.
- The discovery challenges previous assumptions that higher oxygen levels were necessary for early animal life, as these sponges likely lived in low-oxygen conditions.
- While the findings are still debated and require further confirmation, they could greatly enhance understanding of early animal evolution.
