The evolution of a biological species

Usage examples of speciation.

As for me, I am grateful for differentiation and speciation, but I cannot feel as separate an entity as I did a few years ago, before I was told these things, nor, I should think, can anyone else.

If they follow our protocol, it will be anaerobic life at first, then photosynthesis and the first exhalation of oxygen, then respiring life and the great burst of variation, then speciation, and, finally, some kind of consciousness.

The separation of the speakers by migrations had effects on language comparable to the speciation observed by Darwin on various islands of Galapagos.

The size of evolutionary steps, the exact scenario for speciation, is still debated.

No speciation, all working from one genetic blueprint, making a few hundred different forms.

Earth, they suspected the evolution of humanity had been the consequence of a number of speciation steps.

The pithecine form had proved effective and enduring, and there had been a great churning of speciation events, a radiation of ape people.

Rather, speciation relied on a group of animals being isolated from the larger population and put under pressure to survive.

Synthetic Speciation, by Dr Heribert Nilsson, Professor of Botany from the University of Lund, Sweden.

To give an example of the way man operates compared to other animals, consider speciation, which, as we know, tends to occur when a small group of animals gets separated from the rest of the herd by some geological upheaval, population pressure, food shortage, or whatever, and finds itself in a new environment with maybe something different going on.

If that trend held for long, Sax thought, it would lead to a kind of physicalization of class-a late emergence or retroactive unveiling of Marx's bleak vision-only more extreme than Marx, because now class distinctions would be exhibited as an actual physiological difference caused by a bimodal distribution, something almost akin to speciation.

The paper was entitled "Frequencies of Biologic Contact According to Speciation Probabilities.

And we've already come across improbabilities that are way beyond this bound, such as Fred Hoyle's figure for the likelihood of the full complement of human proteins arising through chance, or Lee Spetner's for speciation and convergence.

Brock believes the mummies represent the first clear evidence of a human speciation event,” Merton said, hoping to move things along.
