Description:Excerpt from Biological Lectures: From the Marine Biological Laboratory of Woods Holl, 1899The questions relating to the origin of organic structures must always possess great interest for the biologist, and when I was asked to speak before the students at Woods Holl, it seemed to me that a discussion of recent views bearing on the development of the spore-producing structures of the higher plants, i.e., the Archegoniates and seed-bearing plants, would not be inappropriate.There is good reason to suppose that among plants, as among animals, the most primitive forms were aquatic and it is highly probable that many existing fresh-water algae are but slightly modified descendants of these ancestral types. This is evinced by the great uniformity shown by existing green algae all over the world. Most genera and many species are cosmopolitan, and they exhibit far less variety than is shown by their larger and more specialized marine relations. Presumably the condi tions in fresh water have changed but little, and as the more specialized forms have taken to the land, or have developed in the sea, the few that remained in their primitive environment have been subjected to much less competition, and have prob ably persisted with but little change from very remote times.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
