Week 2: Major transitions

There are two main theories that address the question of how life came to be. The first heterotrophic is the belief that chemical along with the sun, made a 'primeval soup’ which gave rise to more and more complex organisms. This theory was strongly supported by Dawkins. On the other hand the autotrophic theory is the belief that organisms that made their own food probably arose first and then more complex organisms arose out of the first simple organism through natural selection, mutation and adaptation. This theory is supported by Mayhew. I am incline to believe Mayhew version of the origin of life because it is hard to believe that we evolved out of a 'primeval soup,' it is much easier to believe that we evolved from simpler organisms, because that evolution is being proved all the time such as birds evolving from dinosaurs

Domestication

The statement that Charles Darwin made about how the orgin of domesticated animals will remain a major mystery, in a way holds some truth. I mean yeah we have DNA, which answers a lot of the questions that we could think of, it still leaves a lot of room for speculation. Such as if dogs are truly related to wolves why can't the two mate and create pups. And if dogs came from wolves where did wolves come from, or are they the aboriginal species that Darwin speaks of. Moving on from that natural selection had to play some role in the development of dog, but it seems that natural selection would have not favored the domesticated animal, and the genes that were created in favor of the domesticated animal would have been stumped. I mean in order to get a dog you would have to keep crossing the runts of a wolf litter, but it seems to me that nature would not look upon small wolves favorably.

Testing can anyone see this, I am not sure if I am public. Thank you
