It is not always the magnitude of the differences observed between species that must determine specific distinctions, but the constant preservation of those differences in reproduction.
[Some dogs] develop blood feuds with other dogs that are so serious that the only silver lining is a dog's inability to build nuclear weapons in the backyard. -- Patricia McConnell, A Tale of Two Species
The shark is the apex predator in the sea. Sharks have molded evolution for 450 million years. All fish species that are prey to the sharks have had their behavior, their speed, their camouflage, their defense mechanisms molded by the shark.
A small species of pinus was much prized, and, when dwarfed in the manner of the Chinese, fetched a very high price; it is generally grafted on a variety of the stone pine.
High culture can never be obliterated as long as the species continues to produce individuals with the inclination and fortitude to pursue their interests and talents against the grain of the mass culture surrounding them.
I don't think there was a thunderclap or a divine spark that suddenly made one species smart. You can see, in our ancestors, there was a gradual expansion of the brain; there was an expansion of the complexity of tools.
The egg of every species of animal or plant carries a definite number of bodies called chromosomes. The sperm carries the same number. Consequently, when the sperm unites with the egg, the fertilized egg will contain the double number of chromosomes.
Of all the tyrannies that affect mankind, tyranny in religion is the worst; every other species of tyranny is limited to the world we live in; but this attempts to stride beyond the grave, and seeks to pursue us into eternity.
As much horror as we have always created, we are a species that keeps moving forward, seeing new sights in new ways, and enjoying the journey.
One of the characteristics of New Labour - and Miliband is irredeemably of that species - is that, in the guise of a new liberal language, it has adopted the age-old default mode of British foreign policy, namely military intervention.
Possession is not only when the devil plays hide and seek in your brain or poison your medula oblongata with negativity, but it is also when you are under the influence of the same specie as you!
It is thus necessary to examine all things according to their essence, to infer from every species such true and well established propositions as may assist us in the solution of metaphysical problems.
It's very limiting to us as a species, the concept of better-than/less-than. It just seems to be at its end. I'm like, this all fades to black, and it's gone. It's dust. Choose carefully what you obsess about.
Mr. Darwin refers to the multitude of the individual of every species, which, from one cause or another, perish either before, or soon after attaining maturity.
As long as I can remember, I've always had pets. Something about the connection you share with this entirely different species just blows my mind.
We are inhabited by as many as ten thousand bacterial species; these cells outnumber those which we consider our own by ten to one, and weigh, all told, about three pounds - the same as our brain.
As a social primate species, we modulate our morals with signals from family, friends and social groups with whom we identify because in our evolutionary past, those attributes helped individuals to survive and reproduce.
I have had close relationships with three species of wild pigs, each a chance encounter on a different continent, and all continue to enrich my life in surprising ways.
The Ocean Health Index is like the thermometer of the ocean. It will allow us to take the temperature to know what is going on at the global level, trying to integrate different impacts, including overfishing, invasive species, coastal development, a...
Mushrooms are miniature pharmaceutical factories, and of the thousands of mushroom species in nature, our ancestors and modern scientists have identified several dozen that have a unique combination of talents that improve our health.
Well I think on a simple ecological level that the diversity of this planet is important for our survival, that all of our different cultures, people are important to the health of the whole the same way that a species of animal should be saved and a...
