Explanation:
The study of the strata is used to determine what the earth was like back in the past compared to what it is now. Even a tiny dull lump on a rock can tell us about what happened way back when. (btw I love ur pfp)
Observing free‐living animals, performing experiments in the lab, doing theoretical research, and conducting fieldwork. Because a tradition by definition involves some sort of social learning, it is challenging, if not impossible, to determine whether a behavior is traditional without understanding how it is developing.
Free-living animal observations can offer compelling circumstantial evidence of a tradition. However, observation alone has not demonstrated adequate evidence to suggest that social learning contributes to the formation of behaviors of interest, even in the opinion of multiple researchers who have examined potentially traditional behaviors in wild populations.
The applicability of laboratory studies to the comprehension of how habits arise in free-living animals is always subject to debate. Even while they can generate intriguing theories, in-depth assessments of field data cannot test them. A potential direction is provided by field studies that examine how behaviors of interest manifest in population members.
