In the seventeenth century, it was held by some that inside a human sperm there was a minute human being - a homunculus - that was planted inside the womb. Development consisted of the miniature homunculus enlarging and passing through… — 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

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
When, as an undergraduate, I began experiments on these slime molds in 1940, only one other person, Kenneth Raper, was working on them at… — 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
There are good reasons why natural selection has become widely accepted as an explanation of evolutionary development. When applied to mammals and other large… — John Tyler Bonner Copy Share Image
