Final answer:
The Arms Race in the diverse Cambrian fauna suggests intense competition and evolution of defensive and offensive traits among different organisms. The Cambrian explosion was a period of rapid diversification driven by the Arms Race.
Step-by-step explanation:
The Arms Race in biology refers to a phenomenon where different species evolve adaptations to compete with each other for survival. In the context of the diverse Cambrian fauna, the Arms Race suggests that there was intense competition among different organisms during the Cambrian period, leading to the evolution of various defensive and offensive traits.
For example, the Cambrian explosion, which occurred around 541-485 million years ago, was a time of rapid diversification and the appearance of many new organisms. This diversification was driven by the Arms Race as organisms developed new features to better compete for resources and avoid being preyed upon. One notable example is the evolution of hard exoskeletons in trilobites, which provided them with protection against predators.
