Answer

Brief Explanations:

To understand what happened before the Paleozoic era, scientists would look at the time period immediately preceding it, which is the Precambrian time. Fossil evidence from this time can provide insights. The Jurassic period and Mesozoic era come after the Paleozoic, and the emergence of mammals and humans in the Cenozoic era is also long after the start of the Paleozoic.

Answer:

Scientists examine fossil evidence during the Precambrian time.
