Pro has the BoP, and will attempt to prove that the current theory of evolution is not an accurate model of our origins.

Pro should post their argument in the first round.

Good luck!

I hope we can both have fun!

1. Comparative Anatomy, when we look at animals today we see three types of structures Homologous, Analogous, and vestigial. Homologous structures are structures that look alike but preform different functions. An example would bat wings and the human hand both have forearm, wrist, and finger bones. With this we assume that maybe this types of organisms evolved from a common ancestor long ago. The next is Analogous structures these are structures that look different but preform the same function. An example is bat wings and dragon fly wings. This shows us that different organisms evolve to their specific environment. The last is vestigial structures which are structures that are not useful any more. Like the human appendix. This shows us that organisms can evolve out of something based on changes in their environment. It is thought that the appendix was once there to help us process raw plants, but after generations of not eating raw plants it stop have a function later becoming useless.

2. DNA comparisons, we can look at other organisms DNA we see many similarity's. For example chimpanzees happen to share about 96% of our DNA. This tells us that we share a common ancestor.

3. The fossil record, all the of the fossil record has always followed the pattern that evolutionary theory has proposed it will. The farther we go back in the fossil record the harder it is to distinguish between organisms. Lets look at the whale as an example. The whale we know and love today (Harbour Porpoise) has a blowhole at the top of its head with two navel openings. They have this because they breath air and have lungs not gills. With all this in mind evolution would have a good reason to think that whale may have evolved form land mammals not fish. The blowhole being a nose evolved for the ocean. So if we go look at the fossil record we can see a fossil of what we think to be a common ancestor of the modern whale. The Basilosurid whale (Durudon Atroc). This whale has its blowhole in the middle of its face. This is big because if whales evolved from land mammals who most of the time have they're nose on the front of their face. Then this is a Transitional species from a land mammal to modern day whale. Just like evolution says we should find.

I believe that there has been a little missunderstanding. The resolution was "Evolution is not a valid theory", and you are Pro, which means that your job was to argue that evolution is not a valid theory.

I'm sorry for the inconviencence if you thought that you were Con.

AWK im so sorry i see stuff like this all lot and I just assume some times that your anti-evolution.
