Professor of biology Jerry Coyne sums up biological evolution succinctly: [3]. Life on Earth evolved gradually beginning with one primitive species – perhaps a self-replicating molecule – that lived more than 3.5 billion years ago; it then branched out over time, throwing off many new and diverse species; and the mechanism for most (but not all) of evolutionary change is natural selection.
Objections to evolution have been raised since evolutionary ideas came to prominence in the 19th century. When Charles Darwin published his 1859 book On the Origin of Species, his theory of evolution (the idea that species arose through descent with modification from a single common ancestor in a process driven by natural selection) initially met opposition from scientists with different ...
Some people are indoctrinated against the theory of evolution and simply do not think about it. But evolution is a well-established explanation of how life developed on Earth.
Anaximander's hypothesis could be considered "evolution" in a sense, although not a Darwinian one. [10] Empedocles argued that what we call birth and death in animals are just the mingling and separations of elements which cause the countless "tribes of mortal things". [11]
During Peoples' 17-year tenure as president, the university experienced dramatic growth unparalleled by any period in its history. The academic program developed from the baccalaureate up to the ...
Evolution is the change in the heritable characteristics of biological populations over successive generations. [1] [2] It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. [3]
Evolutionists expected one part to change at a time, one change to follow another. In Cuvier's view, evolution was impossible, as any one change would unbalance the whole delicate system. [11] Louis Agassiz's 1856 "Essay on Classification" exemplified German philosophical idealism. This held that each species was complex within itself, had ...
Nevertheless, he rejects extreme versions of postmodern relativism. Evolution is an objective fact, containing objective facts, and those facts are not just aspects of a Western creation myth reflecting the dominant ideology, or an element of the current palaeontological paradigm.
