There seems to be an assumption that evolution has a goal and its........a human. Our ego knows no bounds. They don't realise that a frog is as evolved as we are. The motivation is the enviroment nothing more. There is also NO BLUEPRINT for a species or animal. There is no gold standard human or perfect shark, it is just constant change influenced by the enviroment, hence the term NATURAL selection.
Someone was posting here in the last 12 months claiming that white people are more evolved than african tribal people.
Ignorance can be bliss, but it can also be dangerous.
I remember reading Plato and the concept of isms, so a table is a representation of tableism. There is an ideological and gold standard 'table' concept and from that we can imagine, construct and compare the idea of a table. This concrete thinking is common to the human mind and it inteferes with our understanding of evolution. We look at a shark in 2014 and say THAT is a shark, as if there was a sharkism concept to measure from....but there isn't.
Sharks have changedvover millions of years, so much so the earlier ancestors would be unrecognisable as a 2014 shark, proving the concept of 'isms' incorrect, despite humans looking at the world with that mindset.
I am rubbish at philosophy and may have explained it poorly, sorry if that was the case xxx
