What were the factors that may have contributed to the emergence of hard-bodied organisms during the Cambrian explosion?

The factors that may have contributed to the emergence of hard-bodied organisms during the Cambrian explosion include increased oxygen levels and an earlier extinction event. The breakup of supercontinents may have also allowed for ecological diversification and the isolation of populations. Signup and view all the answers

What evidence of complex multicellular life is provided by the Ediacaran fauna preserved in sandstones in South Australia?

The Ediacaran fauna preserved in sandstones in South Australia provides evidence of complex multicellular life during the early stages of life on Earth. This includes the existence of various soft-bodied organisms that were preserved in the fossil record. Signup and view all the answers
