Moreover, the concern of some that moving DNA among species would breach customary breeding barriers and have profound effects on natural evolutionary processes has… — Paul Berg Copy Share Image
The one process now going on that will take millions of years to correct is the loss of genetic and species diversity by the… — E. O. Wilson Copy Share Image
With the advent of genetic engineering the time required for the evolution of new species may literally collapse. — Dee Hock Copy Share Image
Though we must hold to our faith in the evolution of species, there is little evidence as to how it has come about, and… — William Bateson Copy Share Image
The extinction rate is so huge now, we're to the stage where we've got to set up recombinant ecologies. There are no longer enough… — Bill Mollison Copy Share Image
In the process of evolution, the body lasts for some time and then will take other body and take other body and take other… — Maharishi Mahesh Yogi Copy Share Image
Exchange of breeding individuals between two populations tends to homogenize their gene pools. — Peter R. Grant Copy Share Image
Evolution works by selection, not by instruction. There is no final cause, no teleology, no purpose guiding the overall process — Gerald Edelman Copy Share Image
Speciation does not necessarily promote evolutionary change; rather, speciation 'gathers in' and guards evolutionary change by locking and stabilization for sufficient geological time within a Darwinian individual of the appropriate scale. If a change in a local population does not gain such protection, it becomes-to borrow Dawkins's metaphor at a macroevolutionary scale-a transient duststorm in the desert of time, a… — Stephen Jay Gould Copy Share
“Biodiversity is a result of the process of evolution, and it is also a safety net that helps keep that process going. In order to pass our own genes into the future and enable our offspring to live long and prosper, we must reverse the current trend and preserve as much biodiversity as possible. If we don’t, we will sooner… — Bill Nye Copy Share
Exchange of breeding individuals between two populations tends to homogenize their gene pools. — Peter R. Grant Copy Share Image
Almost nothing is known from hybridization studies about the inheritance of courtship behavior of females, or of their responsiveness to particular male signals. — Peter R. Grant Copy Share Image
To summarize, the particular song a male sings, and the behavioral responses of females to song and morphological signals, are not genetically inherited in… — Peter R. Grant Copy Share Image
The independent role of morphology in mate choice is revealed by the rare instances where the usual association between song and morphology is disrupted. — Peter R. Grant Copy Share Image
The divergence of songs in the new population away from those in the progenitor population would only be prevented if these processes were balanced… — Peter R. Grant Copy Share Image
Plumage features constitute a major component of courtship signals. — Peter R. Grant Copy Share Image
The theory of founder effects does not explain how novel features like plumage traits arise. — Peter R. Grant Copy Share Image
Genes that underlie the capacity to receive, use and transmit information are the evolving properties. — Peter R. Grant Copy Share Image
We observe closely related species in sympatry and infer how they evolved from a common ancestor. — Peter R. Grant Copy Share Image
In the fight between biology and morality, biology has commonly won in the end. — Semir Zeki Copy Share Image
We became Homo sapiens not that long ago, from the scientific perspective, and we've retained a lot of our beast nature. We've done all… — Wangechi Mutu Copy Share Image
“Toshiaki learned that all living organisms were governed by their DNA. He was impressed by perfection of this system.Why did existence have the ability… — Hideaki Sena Copy Share Image
We are somehow the children of the planet, we are somehow its finest hour; we bind time, we bind the past, we anticipate the… — Terence McKenna Copy Share Image
I think the ethics and morals of genetic engineering are very complicated. It intrigues me. — Roger Spottiswoode Copy Share Image
Biochemists and biologists who adhere blindly to the Darwinism theory search for results that will be in agreement with their theories and consequently orient… — Pierre-Paul Grasse Copy Share Image
“A note of caution: epigenetics is also on the verge of transforming into a dangerous idea. Epigenetic modifications of genes can potentially superpose historical… — Siddhartha Mukherjee Copy Share Image
Natural history is not taught in seminary. This is curious, as most people in pastoral ministry are about 567 times more likely to be… — Sara Maitland Copy Share Image
We are coming to a place where the road ends. From here on out, we will be making the road as we walk it,… — Tom Atlee Copy Share Image
