On returning to England, Darwin and an ornithologist associate identified 13 species of finches that he had collected on the GalÃ¡pagos Islands. This was puzzling since he knew of only one species of this bird on the mainland of South America, nearly 600 miles to the east, where they had all presumably originated.
To get the most out of a nap, follow these tips: 1  Keep naps short. 2  Aim to nap for only 10 to 30 minutes. 3  The longer you nap, the more likely you are to feel groggy afterward. 4  Take naps in the afternoon.
Be sure that your baby is only napping for about 1.5 hours in the morning. For your twelve month old, the morning nap should be no longer than an hour. Timing at this age is very important. You want to start the afternoon nap approximately three hours after the end of your morning nap.
