HUMAN EVOLUTION

I never thought that the topic ot the human evolution could seem so interesting to me. I suppose we are too young when we are taught this subject and we are not ready to get the importance of all of this so that we can understand a bit better our present world and ourselves.

Some reflections come to my mind that could be used by any script writer to make another science fiction film. For instance, I wonder what would have happened if homo neanthertalensis hadn't extingished and his intelligence had evolved (evolutioned) like ours. Can you imagine a planet with two different intelligent species? How would our world be nowadays? would the strongest one make the other one slave as we do with animals? could we get on if actually we have difficulties to accept other races? One thing is sure, everything would be absolutely different.

Related to an idea that came up in class concerning to natural selection, stated by Darwing, it was said that human evolution might slow down or even change because nowadays in the developped countries (the 1st world) almost everybody survives despite anatomical or healthy problems thanks to huge advances in medicine, science, hygienic conditions, nutrition, etc. Therefore it could be said that in some aspects we have some control over the natural rules. On the other hand our fight against (the) nature has drawbacks. The quality of human beings is lowering and our faulty geenes will be transmitted to future generations. For example, if a person has heart problems anyway he'll live long and the illness will remain in his sons. In other periods this person would have died and his problem wouldn't have been intherited. Yesterday I heard that's why, in spite of having very good conditions in our life, there are more and more degenerative illnesses.

As for the Flores man whose remains where found some years ago in I don't remember which country in Asia, once I saw something similar in a TV series. They posed that an homo intelligent hairy being had survived hidden till now. It sounds scaring, doesn't it? Obviously it's only a film for enterteining, but what I wonder is wheteher we would be prepared for new scientifical discoveries which could change our idea about the world. We trust science and scientists indeed, but we all know nothing (anything) is closed and research (researchings) make universal theories change. Remember when people used to believe the Earth is flat...
