The Origin of Flight
Evolution has many steep obstacles to overcome. Many are the stupendous design characteristics and environmental balances that can scarcely be understood by today's scientists, let alone mimicked. Yet evolution must work alone with random mutations (usually harmful and therefore discarded) and unthinking natural selection, which cannot see the future or do anything novel on its own.

Tiny Bacteria's Big Challenge to Darwin
Bacteria (prokaryotes) are found everywhere and are a critical foundation of the earth's ecosystem. The prokaryotes are designed to be saprotrophs or "decomposers," breaking down wastes and organic material so that chemical components such as nitrogen can be recycled.
