Population Explosion - An analysis

Plants and animals living in warm, tropical climates evolve faster than those living in more temperate zones, a new study suggests.

The finding, detailed in the May 2 issue of the journal for the Proceedings of the
National Academy of Sciences, could help explain why rainforests have such rich biodiversity compared to other parts of the planet

Full story here


The atricle says that the rate of reproduction and speed of mutation is higher for species near the equator. This is in accordance with the world population list

Top 6 individual countries (descending order of population) listed below are either situated verry close to the equator or are intersected by it.

1. China 1,313,973,713
2. India 1,095,351,995
3. Indonesia 245,452,739
4. Brazil 188,078,227
5. Pakistan 165,803,560
6. Bangladesh 147,365,352

The life-span also is supposedly shorter for such species. This does not seem to be true for humans given the advancement in the medical world. Now, the life-expectancy seems to be prety much related to the health standards in the country
