John Tyler Bonner
John Tyler Bonneris an emeritus professor, now lecturer with the rank of professor in the Department of Ecology and Evolutionary Biology at Princeton University. He is a pioneer in the use of cellular slime molds to understand evolution and development over a career of 40 years and is one of the world's leading experts on cellular slime moulds. Arizona State University says that the establishment and growth of developmental-evolutionary biology owes a great debt to the work of Bonner’s studies...

Changes in size are not a consequence of changes in shape, but the reverse: changes in size often require changes in shape. To put it another way, size is a supreme regulator of all matters biological. No living entity can evolve or develop without taking size into consideration. Much more than that, size is a prime mover in evolution.
It is hard to explain the huge variety of diatoms - a microorganism that has 100,000 species - in terms of natural selection.
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 birth and on to maturity-just like inflating a balloon.
As in all of biology, comparative studies showing differences among species are often helpful for a better understanding of the basic mechanisms; with all its advantages, there is a danger of clinging exclusively to one model organism.
My prime interests are in evolution and development. I use the cellular slime molds as a tool to seek an understanding of those twin disciplines.
The sudden appearance of mushrooms after a summer rain is one of the more impressive spectacles of the plant world.
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 if those variations are inherited, the successful ones will survive and propagate and pass down their desirable traits to succeeding generations.
