An ancient ocean full of giant predators reveals a surprising twist in evolution
来源: ScienceDaily ·
A remarkable fossil discovery in Colombia is challenging how scientists understand major evolutionary changes in Earth's history. Researchers uncovered an incredibly diverse ancient marine ecosystem where giant reptiles, sharks, and other creatures thrived as older evolutionary groups approached extinction and newer ones emerged. They call this previously unrecognized pattern a "Biotic Inflection," suggesting that major transformations in life can occur without mass extinctions.
