I assume that my next post will discuss one of his three or four types of directness. Would be curious to see what others he recognizes.Alex SLhttps://www.blogger.com/profile/00801894164903608204noreply@blogger.comtag:blogger.com,1999:blog-3342041114052632712.post-15449700222240525252014-01-17T07:05:50.229+11:002014-01-17T07:05:50.229+11:00Some one proposed the "Darwin" as the un...Some one proposed the "Darwin" as the unit of evolutionary change; 1% per generation or something like that. Species vary in how different they are from their unique common ancestor. All living species have the same time line from the unique common ancestor of all living things, so they are equally evolved in that sense. But in terms of change compared to ancestors, some have more Darwins than others.<br /><br />Ernst Mayer, in one of his books, discusses goal directed and defined three or four terms for different kinds of goal directeness. I have looked for it and have not found it. Anyone know about it?Jim Thomersonnoreply@blogger.comtag:blogger.com,1999:blog-3342041114052632712.post-53866778234410972512014-01-16T23:38:02.674+11:002014-01-16T23:38:02.674+11:00§§Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3342041114052632712.post-68772732599401858922014-01-16T23:36:51.080+11:002014-01-16T23:36:51.080+11:00Every species alive today is the product of billio...Every species alive today is the product of billions of years of evolution.<br /><br />We are all “equally evolved”.<br /><br />For some, evolutionary success has come from complexity; for others, from retaining, or reverting to, simplicity.
