Speciation Quotes

“Natural selection eliminates and maybe maintains, but it doesn't create... Neo-Darwinists say that new species emerge when mutations occur and modify an organism. I was taught over and over again that the accumulation of random mutations led to evolutionary change [which] led to new species. I believed it until I looked for evidence.”
― Lynn Margulis

“New mutations don't create new species; they create offspring that are impaired.”
― Lynn Margulis

“That natural selection can produce changes within a type is disputed by no one, not even the staunchest creationist. But that it can transform one species into another — that, in fact, has never been observed.”
― Robert J. Sawyer, Calculating God

“Regardless of one's point of view, it's quite easy to see that Darwinism is not in the same league as the hard sciences. For instance, Darwinists will often compare their theory favorably to Einsteinian physics, claiming that Darwinism is just as well established as general relativity. Yet how many physicists, while arguing for the truth of Einsteinian physics, will claim that general relativity is as well established as Darwin’s theory? Zero.”

“This is not a one-off. Over 375 species of New World rats and mice evolved after they colonized South America, and rodents have evolved into over 130 species in Australia and New Guinea just a few million years after their first ancestors (presumably) rafted over on floating vegetation from Indonesia. And about eighty species of lupin plants evolved in the Andes in the last one and a half million years, after they invaded from North America. It would take only a modest 5 per cent of the world’s species to repeat the white-eye, rodent and lupin’s feats (say, generating twenty new species in different geographic locations in a million years) to double the total number of species on our planet.”

“Distant parts of the same continent can also be connected, isolated and then connected again. Asia and Europe form a single landmass, Eurasia, but the oak trees and beech trees that grow in eastern Asia and in Europe are not the same as one another. A single species of beech tree forms cathedral-like forests carpeted in golden autumnal leaves in Europe, but different beech species grow in China and elsewhere in eastern Asia, some with trunks that soar towards the canopy, while others branch close to the ground and jostle for space with bamboo thickets on mountain slopes. The climate of central Asia is too harsh, and these trees survive best in the more moderate oceanic regions that exist towards each end of the Eurasian landmass. Isolated, they have become separate species. European oaks also differ from those in eastern Asia, as though the two regions were giant islands separated by the frigid aridity of the continent’s centre. North American beeches and oaks differ again from those in Europe and Asia. Perhaps 55 million years ago, a new kind of tree evolved: the first oak. It originated, spread, colonized different continents, evolved into different species in different regions and climates, and at least some of them came back together again; acting like a giant, slow-acting global archipelago.”
