An article appeared in Friday’s Missoulian newspaper (6/22/12) and if interested, the scientific findings are documented in the journal Nature – link to article: http://missoulian.com/news/state-and-regional/um-assistant-professor-helps-sequence-bonobo-genome-showing-relation-to/article_6f9ddbee-bc10-11e1-85a6-0019bb2963f4.html
There is a link in the newspaper article that takes you to the Nature Journal. What I found interesting was that though the Chimp and Bonobos are similar in many respects – their behavior differs in important ways. Male Chimpanzees use agression to compete for dominance and obtain sex. In contrast, Bonobo males are highly subordinate to females and do not compete for dominance. Bobobos show intense sexual behavior that often involves same sex partners. Both Chimp’s and Bonobos possess characteristics that are more similar to human traits, than they are to each other. So do you think you have some Bonobo or Chimpanzee in your tree? These findings could establish a genetic correlation or linkage between those people who exhibit dominant – aggressive personalities and those with subordinate – submissive and homosexual leanings.
