Does Evolution Happen Gradually or Suddenly?

The video explores the evolution of complex traits, focusing on the debate between gradualism and sudden mutations. It examines studies on pitcher plants and marine snails, showing how traits can evolve independently before coming together to form new innovations. The findings suggest gradualism plays a significant role, with traits evolving separately and then combining to create new functions.

How did the research on marine snails contribute to our understanding of evolutionary traits?

What does the text suggest about the occurrence of key innovations in different species?

In what ways do the findings from the studies challenge the idea of sudden mutations leading to new traits?
