Summary of Origin Of Species 6th Edition The book was written for non-specialist readers and attracted widespread interest upon its publication.

Like Darwin, Coyne also compares natural selection to the artificial selection used in plant and animal breeding. But these examples of selection—natural as well as artificial—involve only minor changes within existing species. For example, a definition applicable to living, sexually reproducing organisms might make no sense when applied to fossils or bacteria.

The result is a fertile plant that is reproductively isolated from the two parents—a new species, according to the BSC. Indeed, according to evolutionary biologist Douglas J. Only primary speciation—the splitting of one species into two by natural selection—would be capable of producing the branching-tree pattern of Darwinian evolution. But no one has ever observed primary speciation. In Why Evolution Is True, Coyne claims that primary speciation was observed in an experiment reported in Paul Rainey and his colleagues at Oxford University placed a strain of the bacteria Pseudomonas fluorescens in a small vessel containing nutrient broth, and simply watched it.

Oxygen concentration, for example, is highest on the top and lowest on the bottom. The smooth ancestral type persisted in the liquid environment in the middle. Each of the two new forms was genetically different from the ancestor, having evolved through mutation and natural selection to reproduce best in their respective environments. Here, then, is not only evolution but speciation occurring in the lab: the ancestral form produced, and coexisted with, two ecologically different descendants, and in bacteria such forms are considered distinct species.

Exaggerating the evidence to prop up Darwinism is not new. There was no net evolution, much less speciation. When a booklet published by The U. British bacteriologist Alan H. Bacteria, the simplest form of independent life, are ideal for this kind of study, with generation times of twenty to thirty minutes, and populations achieved after eighteen hours.

But throughout years of the science of bacteriology, there is no evidence that one species of bacteria has changed into another. The actual evidence shows that major features of the fossil record are an embarrassment to Darwinian evolution; that early development in vertebrate embryos is more consistent with separate origins than with common ancestry; that non-coding DNA is fully functional, contrary to neo-Darwinian predictions; and that natural selection can accomplish nothing more than artificial selection—which is to say, minor changes within existing species.

Faced with such evidence, any other scientific theory would probably have been abandoned long ago. Judged by the normal criteria of empirical science, Darwinism is false. Its persists in spite of the evidence, and the eagerness of Darwin and his followers to defend it with theological arguments about creation and design suggests that its persistence has nothing to do with science at all.

Given accurate information and the freedom to exercise critical thinking, students could learn from Why Evolution Is True how Darwinists manipulate the evidence and mix it with theology to recycle a false theory that should have been discarded long ago.

Carninci, J. Ponting, P. Chambers, A. John Harshman, E. Braun, M. In , Darwin published On the Origin of Species, a work of scientific literature considered to be the foundation of evolutionary biology. His revolutionary work presented evidence from the Beagle expedition as well as from years of subsequent research and experimentation.

The theory Darwin presented in his book quickly became the subject of heated debate and discussion. It includes an insightful Introduction from leading Darwin scholar Dr John van Wyhe of the University of Singapore, which presents new research and an offers an original perspective on Darwin and his famous work. This high-quality, hardcover volume is a must-have for readers interested in science and scientific literature, particularly evolutionary theory and life sciences.

Darwins Idea, Evolution through natural selection, actually explains the meaning of life; it is the biggest single idea ever, its breadth and scope enormous, its means so perfectly economic, its capacity to shock and excite persist, to this day.

The myriad ways of understanding and expressing the beauty of life are a constant inspiration. Darwin's theory is based on the notion of variation. It argues that the numerous traits and adaptations that differentiate species from each other also explain how species evolved over time and gradually diverged.

Variations in organisms are apparent both within domesticated species and within species throughout the natural world. Variations in colors, structures, organs, and physical traits differentiate a multitude of species from one another. Heredity is the mechanism that perpetuates variations, Darwin argues, as traits are passed from parents to offspring.

What is important about these variations to Darwin, though, is the way they allow species to adapt and survive in the natural world. He gives numerous examples of variations that illustrate the wondrous adaptations that allow species to survive in their natural environments: the beak that allows the woodpecker to gather insects, the wings that allow the bat to fly, the paddles that allow the porpoise to swim, and so on.

Darwin hypothesizes that the minor variations we see within a single species-such as variations in size, shape, and color of organisms-are related to the more distinct variations seen across different species. His theory of evolution explains how variations cause the origin of species. There's a reason why On the Origin of Species is one of the best books of all time. If you haven't read this classic, then you'd better pick up a copy of On the Origin of Species by Charles Darwin today!

Few other books have created such a lasting storm of controversy as The Origin of Species. Its acceptance revolutionized the course of science. This book is an accessible guide to the theory of evolution. It lets the young reader discover how Darwin changed our understanding of the human race and our place within the animal kingdom.
