Aug 22 2012: Ok, just a simple chain of questions here regarding evolution of the human brain...
1. During ancient times, did people count as fast as people living in post- modern societies?
2. Can you multiply 5 digit numbers by another set of numbers with the same number of digits under 20 seconds? Or will you rely on the calculator to do it for you?
3. Regarding question 2: - If you can do them with your brain, then your brain has evolved to deal with complex calculations.
- Solve it with a calculator? Then your brain has just experienced devolution, or it hasn't evolved to that stage at all.
Aug 20 2012: Hmmm... Then that's not entirely true. Evolution makes you stand stronger against disastrous effects which may cripple the entire population. Say for example, cockroaches. These creatures have passed on their generations for ages. They are now even immune to radiation. If a giant tidal wave comes crashing on everywhere on the planet, they have a better survival rate than us humans. Why? It still goes back to evolution. You may say that we can't fly, but we have helicopters and planes to bring us up to the sky. But how many airplanes can you have? Cockroaches have wings, and that makes them escape danger more easily.
We should encourage technologies which are environmentally friendly rather than heavy industrial techs that may have a greater effect on economic and production boosts, but hazardous to every biological being.
Aug 19 2012: You see, how the universe began. There's a proposed theory about it all started in the form of pure energy. Later on many elements are produced like hydrogen and oxygen. Then under some circumstances in a certain amount of heat and pressure another substance is formed.
If we look at these stages of how things change, it is certainly logical that everything in our planet Earth attributes to the same pattern of changes with the universe. With simple elements, a more sophisticated compound is formed. Say for an example: cockroaches who lived millions of years ago. Maybe during the dinosaur ages, they did not have wings. And when natural disasters strike, they change their features to survive in harsh conditions. Same goes for viruses, bacteria, and I do think that this theory of evolution does apply on us humans as well.
Currently, technology(some technology, related to chemicals) are used in our daily lives, which helps us a lot to save energy and time. Some are used in external environments, like detergents may help us remove tough grease and stains. There's nuclear power, to help us generate a vast amount of energy to supply our daily needs. Petroleum fuel is used to generate power to run our engines. BUT. What happens if we consume these chemicals? If we drank water containing these pollutants, or radioactive substances that may even damage our cell structure, then it is surely unwise for us to meddle with nature. All of these lead to the degeneration of our cells, thus deforming our genes and suppressing evolution.
Back to the point of evolution, if industrialization did not start a few decades ago. Will there be so many types of super bugs? Or will there be so many diseases terrorizing the globe? Aren't these - Evolution?
Aug 18 2012: We don't know yet. You should check up the theory about space-time. It generally means space is constantly being produced in the universe. So after so many billions of years, I don't think we know how big has the universe expanded.
