RE: Out of Africa No Longer Viable
You can know when someone is lying to you, when it does not allow you to question their truth, and that is what has happened to many of the hypotheses presented by modern scientists, who do not present themselves as hypotheses but as "scientific facts."
The out of africa theory has had several holes for many years, but for some reason some "scientists" and "academics" ignore some things so as not to invalidate their hypothesis, it is a confirmatory bias, and the worst of all is that they use figures recognized from the past to validate their theories, such as Charles Darwin, despite the fact that modern theory has changed a lot with respect to the hypothesis of Darwin, who was essentially racist, although nobody seems to pay attention to this to this day.
Perhaps the strongest influence on science is the power of the purse. Funding, upon which scientists depend totally, is invariably doled out by political organizations, governments or foundations. Even if such grants didn't come with instructions on what was expected in return, merely directing funds at folks likely to support your political leanings sufficiently skews research.
That is very true, in addition, there is also a factor in the recognition of the investigations. In all types of media, including scientists, recognition is not always given to the best research, in feasibility and possibility, but on the contrary, it gives more importance to those that meet or narrow more to the vision or the interests of the diffuser.
