What were four important findings from this long-term study of the chimps in gombe?

Please provide me with the long-term study of the chimps in Gombe that you are referring to. I need more context to understand what you're asking about and provide accurate findings.

For example, you could specify:

* The researchers involved: Jane Goodall's groundbreaking work is often the first that comes to mind.

* The time period of the study: This will help narrow down specific findings.

* Specific aspects of chimpanzee behavior: Are you interested in their social structure, tool use, or communication?

Once you provide more details, I can help you identify four important findings from the study.
