Step-by-step explanation:
A paleontologist is giving a lecture on alien planets to discuss possibilities of life elsewhere based on Earth's history. By studying fossils, paleontologists can understand how life evolved on Earth and potentially determine if similar conditions could have supported life on other planets. This lecture explores the connections between paleontology and astrobiology, offering insights into the origins of life beyond Earth.
