Which of the following is not taken into consideration to study human evolution?

Excavation studies are important for human evolution research because they allow scientists to recover ancient human populations' fossils and other evidence.

Time dating is essential for human evolution research because it provides a chronological framework for understanding when various hominid species lived and how they are related to one another.

Determining DNA sequencing is also important for human evolution research because it reveals genetic relationships between different hominid species, including humans. Scientists can use this information to better understand the evolutionary relationships between different hominid species and how they have evolved over time.

The existence of an organism is not taken into account when studying human evolution because the mere existence of an organism, whether human or non-human, does not provide information about its evolutionary history.
