Quotes About Speciation

More than 500 million years ago, vision became the primary driving force of evolution's 'big bang', the Cambrian Explosion, which resulted in explosive speciation of the animal kingdom. 500 million years later, AI technology is at the verge of changing the landscape of how humans live, work, communicate,and shape our environment.

According to Darwinian theory, differences in biological form should increase gradually, steadily increasing the number of distinct body plans and phyla, over time. References for first appearances are found in note 5 of this chapter.

If there is as a continuum from self-reproducing molecules, such as DNA, to microbes, and an evolutionary sequence continuum from microbes to humans, why should we imagine that continuum to stop at humans?

I have stated, that in the thirteen species of ground-finches, a nearly perfect gradation may be traced, from a beak extraordinarily thick, to one so fine, that it may be compared to that of a warbler.

Habiendo tenido ejemplares vivos de casi todas las castas inglesas de aves de corral, habiéndoselas criado y cruzado, después de examinar sus esqueletos, nos parece casi cierto que en su totalidad descienden de la raza salvaje india Gallus bankiva.

I certainly look at the modern guys and think they are a different species to when we played. They are fitter and their conditioning is extraordinary.

The movement of animals across the bridge was by no means always in one direction, for although it is true that the more spectacular beasts—mastodon, saber-tooth, rhinoceros—came out of Asia to enrich the new world, other animals like the camel originated in America and carried their wonderful capacities into Asia.

All mammals undergo a certain degree of diversification. Darwin knew that. When he drew a family tree, it had many branches on it.

Evolutionists have been digging fossil strata for about 140 years looking for these hypothetical forms. They have found millions of invertebrate fossils and millions of fish fossils; yet nobody has ever found even one that is midway between them.

On seeing the marsupials in Australia for the first time and comparing them to placental mammals: "An unbeliever . . . might exclaim 'Surely two distinct Creators must have been at work'"

All scientists agree that evolution has occurred - that all life comes from a common ancestry, that there has been extinction, and that new taxa, new biological groups, have arisen. The question is, is natural selection enough to explain evolution? Is it the driver of evolution?

It is hard to explain the huge variety of diatoms - a microorganism that has 100,000 species - in terms of natural selection.

Splitting and gradual divergence of genera is exemplified very well and in a large variety of organisms.

The divergence of songs in the new population away from those in the progenitor population would only be prevented if these processes were balanced by repeated immigration and subsequent breeding: song flow.

From a ball of mud taken from a birds plumage, Charles Darwin raised 82 separate plants, belonging to five distinct species!

Although random mutations influenced the course of evolution, their influence was mainly by loss, alteration, and refinement... Never, however, did that one mutation make a wing, a fruit, a woody stem, or a claw appear. Mutations, in summary, tend to induce sickness, death, or deficiencies. No evidence in the vast literature of heredity changes shows unambiguous evidence that random mutation itself, even with geographical isolation of populations, leads to speciation.

produce new species. One set of parents can produce offspring
