Document Summary
Selective breeding of animals or plants to ensure that certain traits are apparent at higher frequency in next generations. Douglas adams wrote about the four ages of sand1) telescope2)microscope3) computer chip4)fibre optics. Silica sand is melted to make glass, which is used in the above four terms. Anatomical structures of unrelated organisms which function similarly but don"t sharecommon ancestor. The structures/traits at first were different but than later evolved to preform the same function( similar living conditions) A scientific name with a rank of species , with two terms: a generic name and a specific name. He observed that in different parts of the world (even though they had similar conditions) theywere inhibited by distinct kinds of plants and animals, organisms change based on environment. The theory that earth has been affected by sudden, violent events that were worldwide in scope. Major changes in organisms on earth are the result of the catastrophes rather than evolutionary processes.
