Why Sea Lilies Walk
|
| Topic: Origin & Evolution of Life |
03/21/10 |
| Summary: New research has shown that sea urchins have been preying on sea lilies for over 200 million years, and this interaction led to lilies developing the ability to creep along the ocean floor. The study provides a unique look into how organisms are able to evolve in response to environmental pressures over time. |
