%M ZOOGENESIS "^^^ 



Leaves are produced by plants. In order to grow 

 plants must have water. To them water comes in the 

 form of rain. Rain is moisture condensed from the air 

 passing in the form of winds above the earth. Most 

 of this moisture gets into the air through evaporation 

 from the surface of the seas which cover seven-tenths 

 of the area of the world. 



So there really is a close connection between the 

 butterflies and the ocean. This connection is made 

 up of many links which involve almost every line of 

 science. For instance, astronomy plays a part. The 

 emanations from the sun provide the energy by means 

 of which the water is evaporated from the surface of 

 the sea, which causes the winds to blow, and which, 

 acting on the green substance in the leaves of plants, 

 enables them to form organic out of inorganic sub- 

 stances. In other words, the emanations from the 

 sun make possible the physical processes and chemical 

 reactions on which the existence of the butterflies 

 depends. And besides this, the element of time, so 

 far as it affects life, is an astronomical phenomenon 

 dependent upon the spinning of the earth upon its 

 axis and on its course about the sun. 



Weather and climate play an important part in di- 

 rectly affecting the lives of all the butterflies. They 

 also affect them indirectly through their action on the 

 sea, in some cases thousands of miles away. As an 

 example, the alpine butterflies on the mountain tops 

 in south central Asia depend on snow and rain which 

 is brought to that region in the form of water vapor 

 by the higher currents of the air from the Atlantic
