2001 Space odyssey

I an reading the Novel the 2001 Space Odyssey. So far this book has started with the begginning of man kind. The main character so far is Moon Watcher. He is the leader of his tribe. His tribe is struggling to stay alive and with everyday comes more deaths. But one night Moon Watcher notices a large stone has appearded outside of his cave. He has no idea what it is. But later that night the stone begings to light up. Taking control of one mind at a time. The stone is teaching the tribe how to survive. It is also sifting through the tribe to find the fittest. The fittest is clearly Moon watcher.
Moon Watcher is learning the fastest and shows the most cordination. The next day Moon Watcher and his tribe go down to the stream. His tribe is no longer huingry all the time because this stone from outer space has taught them how to hunt. Thus, making them the stringest tribe. The other tribes are all dying out but Moon Watchers is thriving. This book so far is very interesting. It is showing the growing of man in a science fiction kind of way.
