North America Quotes (4 quotes)

In the course of this short tour, I became convinced that we must turn to the New World if we wish to see in perfection the oldest monuments of the earth’s history, so far at least as relates to its earliest inhabitants.
Travels in North America (1845), Vol. 1, 19.
Science quotes on:  |  Earth (638)  |  Tour (2)

The application of botanical and zoological evidence to determine the relative age of rocks—this chronometry of the earth's surface which was already present to the lofty mind of Hooke—indicates one of the most glorious epochs of modern geognosy, which has finally, on the Continent at least, been emancipated from the way of Semitic doctrines. Palaeontological investigations have imparted a vivifying breath of grace and diversity to the science of the solid structure of the earth.
Cosmos: A Sketch of a Physical Description of the Universe (1845-62), trans. E. C. Due (1849), Vol. 1, 272.

What happened to those Ice Age beasts? What caused the mammoth and mastodon and wooly rhinoceros to pay the ultimate Darwinian penalty, while bison and musk ox survived? Why didn't the fauna of Africa suffer the kinds of losses evident in other regions of the world? And if something like climatic change caused the extinction of North America's Pleistocene horse, how have feral horses managed to reestablish themselves on the western range?
(1986)

[O]ne might ask why, in a galaxy of a few hundred billion stars, the aliens are so intent on coming to Earth at all. It would be as if every vertebrate in North America somehow felt drawn to a particular house in Peoria, Illinois. Are we really that interesting?
Quoted in 'Do Aliens Exist in the Milky Way', PBS web page for WGBH Nova, 'Origins.'

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
