When, as an undergraduate, I began experiments on these slime molds in 1940, only one other person, Kenneth Raper, was working on them at that time. In fact, he discovered the model species Dictyostelium discoideum, which is the species used… — John Tyler Bonner Copy Share Image
There are good reasons why natural selection has become widely accepted as an explanation of evolutionary development. When applied to mammals and other large animals, it fits perfectly. But we cannot assume that all evolutionary steps arise from selection, particularly… — John Tyler Bonner Copy Share Image
Changes in size are not a consequence of changes in shape, but the reverse: changes in size often require changes in shape. To put… — John Tyler Bonner Copy Share Image
That the role of size has been to some degree neglected in biology may lie in its simplicity. Size may be a property that… — John Tyler Bonner Copy Share Image
In the seventeenth century, it was held by some that inside a human sperm there was a minute human being - a homunculus -… — John Tyler Bonner Copy Share Image
It is hard to explain the huge variety of diatoms - a microorganism that has 100,000 species - in terms of natural selection. — John Tyler Bonner Copy Share Image
Evolution, cell biology, biochemistry, and developmental biology have made extraordinary progress in the last hundred years - much of it since I was weaned… — John Tyler Bonner Copy Share Image

As in all of biology, comparative studies showing differences among species are often helpful for a better understanding of the basic mechanisms; with all… — John Tyler Bonner Copy Share Image
Any object, whether animate or inanimate, will have a size. Airplanes, boats, or musical string instruments vary in size just like animals and plants,… — John Tyler Bonner Copy Share Image
The reason for natural selection's great success is that it provides a satisfying explanation of how evolution might have occurred: individual organisms vary, and… — John Tyler Bonner Copy Share Image
My prime interests are in evolution and development. I use the cellular slime molds as a tool to seek an understanding of those twin… — John Tyler Bonner Copy Share Image
The sudden appearance of mushrooms after a summer rain is one of the more impressive spectacles of the plant world. — John Tyler Bonner Copy Share Image
