About John Tyler Bonner

John Tyler Bonner (born September 14, 1920) is an American zoologist and evolutionary biologist renowned for his pioneering work on the slime mold Dictyostelium discoideum and his contributions to the field of cellular slime molds. Born in Omaha, Nebraska, Bonner grew up in a family of modest means but nurturing intellect. His early fascination with natural history was kindled during childhood expeditions into the nearby Nebraska forests. He earned his B.A. from Dartmouth College in 1942 and his Ph.D. from Yale University in 1947, where he studied under Theodosius Dobzhansky, a prominent figure in evolutionary genetics. In 1950, Bonner joined the faculty at Cornell University, where he would spend most of his career. His groundbreaking research on Dictyostelium discoideum has significantly advanced our understanding of cellular slime molds and their role in evolution. One of Bonner's most influential works is "The Mold That Changed the World: The Search for the Elemental Organism" (1967), co-authored with his colleague Carl W. Schlichting. This book detailed the life cycle, genetics, and developmental biology of Dictyostelium discoideum, establishing it as a model organism in cellular slime mold research. Bonner's work has been recognized by numerous awards, including the National Medal of Science (1980) and the Balzan Prize for Evolutionary Biology (1997). Despite his many accomplishments, Bonner remains humble and approachable, embodying a spirit of curiosity and dedication that continues to inspire new generations of scientists. His enduring legacy lies in his commitment to unraveling the mysteries of life and advancing our understanding of evolution.

Interpretations of Popular Quotes

"The evolution of complexity is not an accident."

John Tyler Bonner's quote, "The evolution of complexity is not an accident," suggests that the intricate and complex structures we observe in nature did not arise randomly or by chance. Instead, these complexities are a result of the process of natural selection and the slow, incremental changes over time that allow life forms to adapt to their environment and survive. In essence, Bonner is emphasizing that the complexity we see in living organisms, from simple cells to highly sophisticated species, is the product of evolution by natural selection, a process that favors beneficial traits which increase an organism's chances of survival and reproduction.


"In biology, as in art, the unexpected can sometimes be beautiful."

This quote underscores the intrinsic value of discovering the unforeseen and fascinating aspects of nature and life, much like appreciating the surprising elements in artistic creations. It suggests that by exploring biology, we may stumble upon unexpected beauty, which enriches our understanding and admiration for the natural world.


"Everything is connected to everything else."

This quote by John Tyler Bonner emphasizes the interconnectedness of all things in the universe. It suggests that no aspect of our world, whether biological, physical, or abstract, exists independently. Instead, every element, event, and phenomenon is linked to others, forming a complex web of relationships. Understanding these connections can provide valuable insights into the natural world, helping us appreciate its intricate balance and complexity, as well as our role within it.


"Nature is full of surprises."

This quote highlights the unexpected, fascinating, and captivating aspects found within nature. It underscores that there are always more discoveries to be made in our natural world, as well as a reminder of the endless wonders that can arise from studying it closely. Nature's surprises serve as a testament to its complexity and beauty, inspiring curiosity and further exploration.


"Life on this planet has a great capacity for invention."

John Tyler Bonner's quote, "Life on this planet has a great capacity for invention," encapsulates the incredible adaptability and resilience of living organisms on Earth. It suggests that life, in its myriad forms, is inherently innovative, continually finding ways to survive and thrive amidst diverse environmental conditions. This insight underscores our appreciation for the richness and complexity of life, as well as serves as a reminder of the unparalleled potential of life's evolution and diversity.

Any object, whether animate or inanimate, will have a size. Airplanes, boats, or musical string instruments vary in size just like animals and plants, and in all cases, their size and their material construction are totally different matters even though they affect one another.

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.

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.

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 in the majority of the experimental work today.

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.

Evolution, cell biology, biochemistry, and developmental biology have made extraordinary progress in the last hundred years - much of it since I was weaned on schoolboy biology in the 1930s. Most striking of all is the sudden eruption of molecular biology starting in the 1950s.

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.

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 when looking at smaller animals.

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.

That the role of size has been to some degree neglected in biology may lie in its simplicity. Size may be a property that affects all of life, but it seems pallid compared to the matter which makes up life. Yet size is an aspect of the living that plays a remarkable, overreaching role that affects life's matter in all its aspects.

It is hard to explain the huge variety of diatoms - a microorganism that has 100,000 species - in terms of natural selection.
