Researchers have discovered over 100 fossils in the Mackenzie Mountains of Canada, dating back 567 million years, that provide insight into some of the earliest complex life forms. These fossils suggest that deep-sea environments were crucial for the evolution of early animals, including those that moved and reproduced sexually.
- 01The fossils were found in the Mackenzie Mountains, Northwest Territories, Canada, and date back to 567 million years ago.
- 02Key fossils include Dickinsonia, a frisbee-shaped creature, and Kimberella, which may relate to modern mollusks.
- 03The study suggests early animals coexisted for millions of years, challenging previous theories of distinct evolutionary phases.
- 04Funisia, a tubular organism, is noted as one of the first creatures to reproduce sexually, sending sperm and eggs into the water column.
- 05The research indicates that the deep sea provided a stable environment for early animal evolution, contrary to the assumption that life originated in shallower waters.

A recent study published in *Science Advances* has unveiled a significant collection of fossils in the Mackenzie Mountains of Canada's Northwest Territories, dating back 567 million years. This discovery sheds light on some of the earliest complex life forms during the Ediacaran period, which predates the Cambrian explosion of biodiversity. The research team, led by Scott Evans from the American Museum of Natural History, collected over 100 fossils that include both mobile and sexually reproducing organisms. Notable finds include Dickinsonia, a frisbee-like creature that absorbed algae, and Kimberella, which may be a precursor to modern mollusks. The fossils challenge the traditional view of distinct evolutionary phases, indicating that various animal groups coexisted for millions of years. Additionally, the study highlights the deep-sea environment as a crucial cradle for early animal life, suggesting that these organisms thrived in stable conditions that offered less temperature variation. This research not only extends our understanding of early animal evolution but also emphasizes the importance of deep-sea habitats in shaping life on Earth.
