We are ALL in transition. You cannot say an eye is "complete." What is complete for you? You think our ears are complete? Well look how well bats can hear - they can hear sonic waves. Dogs can hear the footsteps of their owners way far away from what we can hear and birds can sense whether it is going to rain. There is no absolute or complete - that is all arbitrary.

You clearly have no idea of how evolution works - I suggest you open a high school biology text book to understand how evolution works. Who's to say my tongue is half developed and a dogs is fully developed. Is our nose fully complete? Well, we can smell only a small fraction of what dogs can smell - they can smell if someone's been somewhere several hours ago or smell out drugs at the airport.

Everything is constantly in transition - we are all adapting to the changing environment around us.

Look at this image - this will show you how evolution works: http://img205.imageshack.us/img205/7425/23734.png

Also, I urge you to show us how penguins from a million years ago look the same as they do today. Please provide us concrete scientific proof. I doubt your claims are true. Don't make claims without evidence to back them up.

Here is the evidence and documentation for the evolution of mammalian ears. http://en.wikipedia.org/wiki/Evolution_of_mammalia... Read it word for word. Evolution is not just in the past - it is constantly and continuously happening.

Also you have to know, evolution does NOT have a predetermined route. All living things do not have a perfect and ideal being they hope to be - instead they are constantly trying to evolve to match the changing environment. Especially with global warming changing the world's climate so rapidly (climate change that without human pollution would take hundreds to thousands of years is happening in a matter of decades), that many animals can't keep up and as a result are dying out quickly. Only those that evolve quickly like mosquitos - which are getting smarter and resistant to our bug sprays by the days (since they reproduce so often) that they are alive.

Diseases evolve very quickly too - that is why certain medicines lose it's effect to diseases after a while as they gain resistance to the drug - this is all evolution at work. Only the fittest individuals can survive.
