The statement "By examining fossils, paleontologists cannot tell how long ago organisms lived" is False. Paleontologists study fossils to understand the history of life on Earth, including the age at which various organisms existed. Through multiple techniques, such as relative dating and absolute dating methods (including radiometric dating), scientists can determine not only the existence of these organisms but also approximate timelines for when they thrived.

Fossils are often found in sedimentary rock layers, and the principle of stratigraphy allows paleontologists to discern the relative ages of different layers. Additionally, radiometric dating can provide more precise ages of certain types of rocks or fossils by measuring the decay of radioactive isotopes within them.

Overall, fossil examination is a crucial tool that enhances our understanding of biological evolution and the timeline of life on Earth. Therefore, the ability to determine how long ago organisms lived based on fossil evidence is a key aspect of paleontological research.
