A Quote by Alfred Russel Wallace
Every species has come into existence coincident both in space and time with a pre-existing closely allied species.

Moreover, all our knowledge of organic remains teaches us, that species have a definite existence, and a centralization in geological time as well as in geographical space, and that no species is repeated in time.
Palaeontological research exhibits, beyond question, the phenomenon of provinces in time, as well as provinces in space. Moreover, all our knowledge of organic remains teaches us, that species have a definite existence, and a centralization in geological time as well as in geographical space, and that no species is repeated in time.
Clearly, we are a species that is well connected to other species. Whether or not we evolve from them, we are certainly very closely related to them. A series of mutations could change us into all kinds of intermediate species. Whether or not those intermediate species are provably in the past, they could easily be in our future.
Researchers keep identifying new species, but they have no idea about the life cycle of a given species or its other hosts. They cut open an animal and find a new species. Where did it come from? What effect does it have on its host? What is its next host? They don't know and they don't have time to find out, because there are too many other species waiting to be discovered and described.
We have seen that blood united to blood in the case of but remotely connected species of animals, kills; blood united to blood in the case of more closely allied species of animals does not kill. The physical organism of man survives when strange blood comes in contact with strange blood, ... but clairvoyant power perishes under the influence of this mixing of blood, or exogamy.
Perhaps walking is best imagined as an 'indicator species,' to use an ecologist's term. An indicator species signifies the health of an ecosystem, and its endangerment or diminishment can be an early warning sign of systemic trouble. Walking is an indicator species for various kinds of freedom and pleasures: free time, free and alluring space, and unhindered bodies.
Vampires as creatures have evolved over time as different vampire bloodlines have hit different populations of humans. Every once in a while the blood will make something new and mutate into a new species with different powers, abilities, weakness, physical characteristics, and so on. I don't want to give anything away, but there are whole species and branches that date all the way back to pre-modern times.
We are the most dangerous species of life on the planet, and every other species, even the earth itself, has cause to fear our power to exterminate. But we are also the only species which, when it chooses to do so, will go to great effort to save what it might destroy.
There is part of a structure in which every species is related to every other species. And they're built up on species, like a pyramid. The simpler cell organisms, and then the more complicated ones, all the way up to the mammals and birds and so forth. We call it 'developing upward'... The whole thing depends on every part of it. And we're taking out the stones from the pyramid.
The succession of individuals, connected by reproduction and belonging to a species, makes it possible for the specific form itself to last for ages. In the end, however, the species is temporary; it has no "eternal life." After existing for a certain period, it either dies or is converted by modification into other forms.
There are millions of different species of animals and plants on earth--possibly as many as forty million. But somewhere between five and fifty BILLION species have existed at one time or another. Thus, only about one in a thousand species is still alive--a truly lousy survival record: 99.9 percent failure!
Let us investigate more closely this property common to animal and plant, this power of producing its likeness, this chain of successive existences of individuals, which constitutes the real existence of the species.
For millions of years, on average, one species became extinct every century.... We are now heaving more than a thousand different species of animals and plants off the planet every year.
Humanity is part of nature, a species that evolved among other species. The more closely we identify ourselves with the rest of life, the more quickly we will be able to discover the sources of human sensibility and acquire the knowledge on which an enduring ethic, a sense of preferred direction, can be built.
The commitment must be much deeper - to let no species knowingly die; to take all reasonable action to protect every species and race in perpetuity.
The human species was not born into a market economy. Bees won't sell you honey if you offer them an electronic funds transfer. The human species imagined money into existence, and it exists - for us, not mice or wasps - because we go on believing in it.
