[11][12] Henneberg graduated summa cum laude in 1973 in Biology (Physical Anthropology) at Adam Mickiewicz University, Poznan, Poland.

[13] In 1981, Henneberg was imprisoned by the Polish People's Republic for his role in the Solidarity trade union movement and his efforts to reconstitute the academic board at his university, as well as organise strikes.

[17][18][19] Homo floresiensis, also known as 'Hobbit Man', was discovered around the same time as The Lord of the Rings trilogy was in cinemas and generated considerable global news media interest.

However, this view has been criticised by the noted physical anthropologist Chris Stringer who in 2011 wrote of Homo floresiensis deniers generally, "I think they have damaged their own, and palaeoanthropologist's, reputation.

[25][26] Henneberg's team of researchers theorised in 2013 that another popular notion - that of humans being more intelligent than other animals - is inaccurate, as species merely think differently.

It takes a persistent copulation every other day for three months to achieve conception, on the average... All this leads to the conclusion that humans use sexual intercourse for bonding and pleasure, rarely for conception.”[28]Henneberg believes that evolutionary biologists are so enthusiastic to declare new species and links in human evolution that they have overlook the possibility that each species, like Neanderthals, are merely variations of homo sapiens.

This is because protein is processed by the human body after fats and carbohydrates, which are conventionally thought to contribute to weight gain.
