CREATION BY EVOLUTION 



an additional piece due to a pulling out of the upper lip. 

 This is the evolutionary way! 



We live in what has sometimes been called the "age of 

 insects," for of these there are more than a quarter of a 

 million different kinds. Now there must be some meaning 

 in the fact that these can be classified in an orderly way; 

 that one can for many kinds make plausible "genealogical 

 trees." Often one species, with its varieties, seems to grade 

 into another. In many parts of the animal kingdom there 

 are types that link great classes together. Thus the old- 

 fashioned Pertpatus type, a little creature somewhat like a 

 permanent caterpillar, has some worm characters and some 

 centipede characters. It is to some extent a connecting link. 

 The oldest known bird, a fossil beautifully preserved in 

 lithographic stone of Jurassic age, has numerous reptilian 

 features, such as teeth in both jaws, a long lizard-like tail, 

 a half-made wing, and abdominal ribs. Yet it was a genuine 

 feathered bird! And this fossil is unexplainable unless we 

 recognize the fact that this bird had reptilian ancestors. 



Very striking, again, are the embryological facts which 

 show that the development of the individual is like a con- 

 densed recapitulation of the probable evolution of the race. 

 An embryo bird is for some days almost indistinguishable 

 from an embryo reptile; they progress along the same high- 

 road together; but soon there comes a parting of the ways 

 and each goes off on its own path. The gill-slits of fishes 

 and tadpoles — the slits through which the water used in 

 breathing passes — are persistent in all the embryos of rep- 

 tiles, birds, and mammals, though in these higher back-boned 

 animals they have nothing to do with respiration. All of 

 them are merely transient passages except the one that 

 becomes the "eustachian tube," which leads from the ear 

 to the back of the mouth. They are straws which show how
