What we're seeing behind this particular curtain that's being pulled back is how credentialed academics have been able to promulgate falsehoods throughout the system and get their wrong-headed "theories" taught for decades if not centuries in schools of all levels, long after contrary evidence gets purposely subverted by these same academicians.
There are many such fiefdoms that are amazingly and successfully resistant to the assimilation of new, factual information.
What we think we know is in large part wrong and a big reason is that so-called scientists (and others, e.g., archaeologists, art historians, etc.) are able to hold sway to marginalize very credible reports, often by well-trained observers.
A very good book on topics that elucidate such problems is, "Everything You Know is Still Wrong," by Lloyd Pye.
"Evolution theory" today is a far cry from what was understood in Darwin's time, over 150 years ago.
The breadths, depths & granularity of today's understandings are orders of magnitude greater than Darwin could even imagine.
And yet, and yet... in all those years basic evolution theory has never been verifiably falsified.
Indeed, much of what was "just theory" to Darwin has now been observed as facts.
Point is: it's important we keep in mind scientific distinctions between observed facts, confirmed theories, falsifiable hypotheses and research "brain storming".
