What can you say that you know one thing about evolution?
Answers
Quite aside from anything else, you are still setting far too much store by the people who are speaking, and far too little by what they are actually saying. Evaluate the evidence for yourself, if you can -- what one PhD says, or a Professor, or even a Nobel Laureate or two, means nothing. They may be right or they may be wrong, but who they are is irrelevant to that....

I have never understood the argument about the eye, OP. Could you please explain it more?
As far as I can see... an eye can be evolved. Starting off with a few cells that can differentiate between light and dark, then movement, then better detail, and eventually colour.
Clearly, I am not scientific... but could you explain simply, why, please? Xx

.// Evolution is a continuous process.//
erm not really Jim

and can I say in a balanced fashion that all this talk of Abers being dogs and cats - I am really feeling quite stalked? just saying - and squealing of course
oh er and yes before anyone says it
evolutionary theory has evolved since 1859
uni courses are called evo devo - god know what the long words are - and not that popular

I am a great one for - it is explained because it exists
( actually that is called an existential argument)
there may be an evolutionary biologist out there - AB has an astounding spectrum of talents - Jim as a theoretic physicist and Barmaid as a lawyer -
a formal zoology course is a good starter - you dont just get a cows eye and a cocktail stick and jan it - he course will cover how organisms perceive light
there are light sensitive spots on jelly fish eg
you get a single light pereiving spot ( oops cant remember which one)
and then the complex eye of insects - ommatidia grouped together
( I really used to enjoy zoology but now there is a lot of behavioral zoo which I find less inspiring)
the eye of the bird I think has a coloured oil drop and a simple receptor - which allows colour perception
and then there is the mammalian eye which seems to start again. starts off as a golf ball (neuro) and then indents to an egg cup - and in the rim of the cup there develops the pupil - those bits are derived fro, mesectoderm and not neuro
so there is a redesign from scratch even tho there were working models of a different design which werent bad
and even Darwin worked out that the inferior designs would not allow the eventually superior design to develop - as it has to go thro inferior low functioning prior forms and should get die from lack of fitness
and then Darwin said - I dont know, too hard for 1860

Something which appears to have "steps" of rapid change, most likely due to rapid environment change, doesn't necessarily stop in between. It still continues with the mutations, beneficial ones getting distributed though the populous even if the present environment doesn't weed out those without it. So it's still continuous.
It's no good railing about folk not wanting to use their time sitting through videos posted. Whatever is in the video still has to be posted here to be discussed, and the onus is on the link poster not those they are debating. Using links to show support of something aready claimed/posted, fine, but don't just post and expect everyone to go look. Links are reference only in a debate. They aren't the debate itself.

Evolution offers an explanation of the mean and process by which complexity arises (evolves) from simpler forms. Creation, posing as an alternative 'explanation', offers no explanation whatsoever for how complex systems came to be. Failure or refusal to fully understand and accept one explanation is no justification for accepting 'another' that explains nothing at all.
