Life on Earth May Have Begun with a Sea Sponge
- "Based on new genetic tests, the team of scientists can say with confidence that molecules produced by sea sponges have been found in 640-million-year-old rocks. These rocks significantly predate the Cambrian explosion, the period 540 million years ago in which most animal groups took over the planet, suggesting that sea sponges may have been the first animals." - excerpt from article in The Christian Science Monitor.
