Biological Clock In Plants And Animals
Some how, the animals and plants seem to remember the seasons perfectly. The reason for this is the biological clock in them. Flowering patterns, mating season, menstrual periods are some of the wonderful things that happen like clock work precision because of this biological clock. This is the precise mechanism that helps migratory birds trace their place correctly after flying for more than 8000 miles. Migratory birds from Siberia move to India in the harsh winter at Siberia. Here they find the climate warm enough and engage in reproduction. When it is summer at Siberia again they fly back with their siblings.
