  • We do not have a definite answer to the question, why our ancestors
    abandoned their arboreal habitats. But it can be credited as the first
    evolutionary blunder, which has today precipitated as global
    environmental challenges staring at us.
  • Introduction of money qualifies as the second evolutionary blunder
    (though social). Since then man as a species has lost wealth to become rich.
  • Homo sapiens is perhaps the only species, which gives preference to males
    over females. This species has polluted the biosphere to a seemingly irrecoverable extent.
