Taking isolated similarities by themselves, the theory of evolution appears to be quite reasonable... However, it seems that too much weight has been placed on similarities without questioning the differences.To the embarrassment of many a very intelligent man and woman of science, overly confident conclusions and arrogant statements have been made based on such similarities that have, on occasion, turned out to be not only wrong, but painfully wrong.
For example, in 1990, Richard Leakey himself said that, "If pressed about man's ancestry, I would have to unequivocally say that all we have is a huge question mark.
To date, there has been nothing found to truthfully purport as a transitional specie to man, including Lucy, since 1470 was as old and probably older.
The term can also be applied to larger groups of organisms, as in "the adaptive radiation of mammals." adaptive strategies: A mode of coping with competition or environmental conditions on an evolutionary time scale.
Species adapt when succeeding generations emphasize beneficial characteristics.
The heliocentric view pictures the sun as motionless at the center of the solar system with all the planets, including the earth, in motion around it.
Geocentricity is a conceptual model of the form of the universe which makes three basic assertions about the nature of the earth and its relationship to the rest of the universe. A geocentric model of the universe seems first to have been formalized by Ptolemy, the famous Greek astronomer who lived in Alexandria around A. This model was generally accepted until Copernicus published his heliocentric model in 1543.
Then, even if circumstances change such that it no longer provides any survival or reproductive advantage, the behavior will still tend to be exhibited -- unless it becomes positively disadvantageous in the new environment.
adaptive radiation: The diversification, over evolutionary time, of a species or group of species into several different species or subspecies that are typically adapted to different ecological niches (for example, Darwin's finches).
