Listening is a more natural way of learning, when compared to reading. Written language only began at around 3200 BC, but spoken language has existed long ago.

Learning by listening is a great way to:
- increases imagination and understanding
- improves your listening skills
- improves your own spoken accent
- learn while on the move
- reduce eye strain

Now learn the vast amount of general knowledge available on Wikipedia through audio (audio article). You could even learn subconsciously by playing the audio while you are sleeping! If you are planning to listen a lot, you could try using a bone conduction headphone, or a standard speaker instead of an earphone.

SUMMARY
=======
Butterfly evolution is the origin and diversification of butterflies through geologic time and over a large portion of the Earth's surface. The earliest known butterfly fossils are from the mid Eocene epoch, between 40-50 million years ago. Their development is closely linked to the evolution of flowering plants, since both adult butterflies and caterpillars feed on flowering plants. Of the 220,000 species of Lepidoptera, about 45,000 species are butterflies, which probably evolved from moths. Butterflies are found throughout the world, except in Antarctica, and are especially numerous in the tropics; they fall into eight different families.
