@farmerman,
Read 'Evolution: The Human story' By Dr. Alice Roberts- Perhaps the only Evolution professional that does not spend half the book as an alter to their own greatness.
Also, Evolution 'Trails from the past' by Cela-Conde, J. Ayala- Controversial text but extremely interesting.
Obviously I'm dealing with persons who have only a google education. They don't know or don't care to admit how google is politically edited to the far left(as far from religion as possible) and surprisingly, edited to the far right on some occasions.
For proof simply read the google version of WWII-As far right as possible. War crimes by the Red Army and the Wehrmacht are front page and carried on to the slightest detail-War crimes of America are just unfounded rumors.
For proof simply read the google version of The Vietnam war-As far left as possible. A far left bonanza of the sorry war effort and the evil forces in the American hierarchy in a stupid, unpopular war. Of course not one mention that the Far Left politics in Washington are the ones that started the damn war in the first place.
Anything read from google their bizarre political correctness needs to be taken in to account.
Java Man is not in the direct human line that for decades it was called 'the missing link'
Lucy is from many different bones that were found in the same area. Rib bones #3 and #4 are not from the same individual. Only someone chained to googles weirdness would not know this.
Bottom line is that at anytime a new discovery could change the entire book on evolution- so said evolution is based on 'available facts' and 'accepted facts'. A species that walked Africa for millions of years-Ardipithecus kadabba we have one very small bone to study. It's name means 'Basal family ancestor' and it is not related to afarensis at all. Now how can this be? It can be because we have not found enough remains to know for sure just where it belongs. A new discovery could happen tomorrow-and change evolution forever.
The study of evolution is not solid-it is liquid and it slouches because science has so little evidence to go by. You can bet the whole house that nothing challenging like this will ever be found on google.
THat is what you need to understand.
