Evolution (ev-o-lu'-shun) [evolutio; cvolvete, to unroll] 



1. The development or temporary growth and organic 

 change that take place in the uterus during pregnancy. 



2. In biology, (i) the doctrine of incasement or 

 preformation of the early physiologists, which sup 

 posed that all parts of the fully-formed animal or 

 plant were present in a minute form in the germ. 

 Cf. Epigenesis. (2) The doctrine of descent often 

 spoken of as Darwinism, based upon the capacity of 

 every plant and animal to produce other individuals 

 of a like kind, but varying to a greater or less degree 

 according to the differentiation induced by special 

 environment and natural selection. Cf. Pangenesis, 

 Blastogenesis, Epigenesis, Ontogeny, Phytogeny, Natu- 

 ral Selection. E., Factors of, the recognized factors 

 of evolution are at least five, viz. : (I) Pressure of 

 an environment affecting function and function affect- 

 ing structure, and the changed structure and function 

 inherited and integrated through successive genera- 

 tions. (2) Use and disuse of organs reacting on 

 growth-force and producing change in form, structure, 

 and size of parts, and such change inherited and in- 

 tegrated through successive generations. (3) Natural 

 selection among individuals of those most in accord 

 with an ever-changing environment — or, as it has been 

 otherwise called, " survival of the fittest." (4) Sex- 

 ual selection : the selection by the female, among vary- 

 ing male individuals, of the strongest or the most 

 attractive. .Among mammals, the selection is mainly 

 of the strongest, as decided by battle ; among birds, of 

 the most attractive, as determined by splendor of color 

 or beauty of song. (5) Physiologic selection, or selec- 

 tion of those varieties the individuals of which are 

 fertile among themselves, but sterile or less fertile with 

 other varieties and with the parent stock. This has 

 also been called " segregate fecundity" by Gulick 

 and homogamy by Romanes. These five factors are 

 not universally recognized. The first two are Lam- 

 arckian, the second two Darwinian factors. In the 

 Lamar cki an factors the changes occur during in</i- 

 vidual life, and the offspring is supposed to inherit 

 them unchanged. In the Darwinian factors, on the 

 contrary, the changes are in the offspring, and the indi- 

 viduals during life are supposed to remain substanti- 

 ally unchanged. The fifth factor has been brought 

 forward by Romanes and Gulick and is not yet uni 

 versally recognized. (6) To these recognized factors 

 of organic evolution must now be added, in human 



lulion, another and far higher factor, viz., conscious, 

 voluntary cooperation in the work of evolution, con- 

 seioiis striving for the betterment of the individual and 

 of the race. This factor consists essentially in the 

 formation and pursuit of ideals. This is called a fat i"i . 

 but it is also much more than a factor. It stands in 

 place of nature herself- -it is a higher, rational nature 

 using all the factors of physical nature for its own 

 higher purposes. To distinguish the evolution deter- 

 mined bj this factor from organic evolution, it is called 

 progres Underlying all these* factors as their nee-
