In January [2002], Indian marine scientists discovered what may be the more extensive remains of two ancient cities in the Gulf of Cambay.

These creatures evolved in this harsh environment through natural selection.

However, the highly successful human occupation of the area that began approximately 10,000 years ago depended largely on cultural adaptations, rather than biological ones.

Chert, jasper and quartzite were often used by humans during this period. With the right stewardship, Lal says, the agricultural soils of the world have the potential to soak up 13 percent of the carbon dioxide in the atmosphere today - the equivalent of scrubbing every ounce of CO2 released into the atmosphere since 1980.

[....] For millions of years, a natural partnership between plants and soil microbes has helped regulate carbon dioxide levels in the atmosphere.

[NP] The invention of agriculture some 10,000 years ago disrupted these ancient soil-building processes.

When humans started draining and plowing up the natural topsoil for planting, they exposed the buried carbon to oxygen, creating carbon dioxide and releasing it into the air.
