Question

please give me an example from the animal kingdom to support your answer.

Answer 1

Thinking about evolution can be traced as far back as Ancient Greece. Plato ( 427-347 B.C.) and his student Aristotle ( 384-322 B.C.) held opinions contrary to any form of evolution. Plato believed in a philosophy called idealism. He conceived that there were two coexisting worlds: an ideal real world and an imaginary imperfect one, humans perceive with their senses. Plants and animals were mearly imperfect representatives of the ideal forms. Only the ideal forms were real. Evolution cannot occur since the real organisms are already perfect. Aristotle questioned Plato's thinking and believed organisms were placed on a ladder of increasing complexity. Each organism had an immovable place on this ladder and each rung was occupied. His view of life was fixed and incapable of evolving. This view of life prevailed for over 2,000 years.

The creationist-essentialist dogma, that species were individually created and fixed, became embedded in Western thought while Judeo-Christian culture fortified prejudice against evolution.

Answer 2

The following website explains some of the pre-Darwin views of evolution, which allows them to be contrasted:

This site is good for Aristotle, specifically:

A simple example is that he defined all fish as egg layers when some give live birth (ie guppies.) Now, the live bearer fish are essentially just the same as other fish, only they carry their eggs with them in something that's not really a womb. His other problem is dualizers- animals that he defined as "being both and neither" when it came to membership in his classification system. A good classification system has few exceptions, if any, his has lots.

Answer 3

large classification: a million. Vertebrates (with a backbone) 2. Invertebrates (without a backbone) further classification: a million. Porifera (sponges) 2. Cnidaria (jellyfish, hydras, sea anemones, Portuguese guy-of-wars, and corals) 3. Platyhelminthes (flatworms, consisting of planaria, flukes, and tapeworms) 4. Nematoda (roundworms, consisting of rotifers and nematodes) 5. Mollusca (mollusks, consisting of bivalves, snails and slugs, and octopuses and squids) 6. Annelida (segmented worms, consisting of earthworms, leeches, and marine worms) 7. Echinodermata (consisting of sea stars, sea cucumbers, sand funds, and sea urchins) 8. Arthropods (consisting of arachnids, crustaceans, millipedes, centipedes, and bugs) 9. Chordata (animals with nerve chords - this team incorporates the vertebrates)

Answer 4

Aristotle grouped animals by the way they moved; in his system all things that fly would be in the same group (bats, birds, and bees).
