But the fact is that the proportion of other _Foraminifera_ is exceedingly small, nor have I found as yet, in the deep-sea deposits, any such matters as fragments of molluscous shells, of _Echini_, &c., which abound in shallow waters, and are quite as likely to be drifted as the heavy _Globigerinoe_. keywords: acid; air; animals; area; atlantic; bodies; body; carbonic; case; chalk; changes; clay; coal; conditions; course; day; deposit; depths; development; distribution; doctrine; doubt; earth; end; epoch; evidence; existence; existing; fact; fathoms; fauna; feet; footnote; formation; forms; geological; geology; globigerinoe; great; history; hypothesis; knowledge; land; life; living; matter; means; miocene; modification; mud; nature; new; north; ocean; order; organisms; parts; period; physical; place; plants; present; question; reason; red; remains; results; rise; rocks; science; sea; series; south; species; structure; substance; sugar; surface; things; time; types; vegetable; water; way; world; years; yeast cache: 10060.txt plain text: 10060.txt item: #2 of 9 id: 16136 author: Huxley, Thomas Henry title: American Addresses, with a Lecture on the Study of Biology date: None words: 35458 flesch: 54 summary: Facts of this kind are undoubtedly fatal to any form of the doctrine of evolution which postulates the supposition that there is an intrinsic necessity, on the part of animal forms which have once come into existence, to undergo continual modification; and they are as distinctly opposed to any view which involves the belief, that such modification as may occur, must take place, at the same rate, in all the different types of animal or vegetable life. But, further, it is expressly stated that aquatic animals took their origin upon the fifth day, and not before; hence, all formations in which remains of aquatic animals can be proved to exist, and which therefore testify that such animals lived at the time when these formations were in course of deposition, must have been deposited during or since the period which Milton speaks of as the fifth day. keywords: animals; biology; birds; bones; day; end; evidence; evolution; existence; fact; forms; history; horse; human; hypothesis; knowledge; life; man; nature; place; plants; present; remains; series; structure; things; time; university; way cache: 16136.txt plain text: 16136.txt item: #3 of 9 id: 16487 author: Conn, H.
