What makes John Tyler Bonner famous?

While we may be familiar with James Watson, Francis Crick, and Rosalind Franklin, we forget one of the influential evolutionary biologists. John Tyler Bonner was an American biologist and professor known for his work in the developmental and evolutionary biology field.

Bonner’s research focused on cellular slime molds, single-celled organisms that reproduce by fission and can be grown in test tubes without a host organism (like bacteria). He was one of the first scientists to study evolution using these cellular slime molds.

His work has had a lasting impact on evolutionary biology and developmental biology. It paved the way for other scientists to develop their theories about evolution or development over time.

What makes Simon Conway Morris famous?

Ever wonder where our ancestors came from? You might not think you needed to. After all, we live in a time when there are more species on the planet than ever.

We have a pretty good idea of how humans and apes evolved from what was once a common ancestor. But the answer to that question—and our place in the scheme of life on Earth—may not be as simple as you think.

Simon Conway Morris is an evolutionary biologist who has spent his career studying Cambrian fossils and their relationship to modern organisms. 

If you’ve read Stephen Jay Gould’s Wonderful Life, you know that he used Morris’s discoveries to show how the Cambrian explosion happened.

What makes Pierre Chambon famous?

Pierre Chambon, who died at 87, was a French biologist who gained recognition for his work on nuclear hormone receptors, which he cloned and studied.

Chambon identified RNA Polymerase II (B) when studying transcription. He earned a Louisa Gross Horwitz Prize for discovering the nuclear receptor superfamily.

Chambon’s work came when scientists were still trying to understand how cells regulated their genes. He helped identify nucleosomes (the smallest unit of chromatin ) and how they organize themselves into larger structures.

What makes Andrew Z. Fire famous?

Andrew Z. Fire is an American biologist and former student of Philip Sharp, who won the Nobel Prize in 2006 for his work on RNA interference.

He co-discovered RNA interference (RNAi), which works by silencing genes that are not being expressed properly. Fire shared half of his Nobel Prize with Craig C. Mello.

Andrew Z. Fire is also known for his role in developing methods that allow scientists to manipulate genes by using RNA as a molecular tool rather than DNA. 

His research has helped unravel many mysteries about how cells regulate their activities. This includes how they respond to infection or control development throughout life stages.

What makes Sydney Brenner famous?

If you’re a fan of science, you might be familiar with Sydney Brenner. He wrote more than 1,000 publications and is known for his research in developmental biology, which he began at Berkeley’s Molecular Sciences Institute.

Born in South Africa, Brenner first became interested in genetics while a graduate student at the University of Oxford. He was working on the genetic code when he realized that there were gaps in knowledge about how developmental processes occur. 

In particular, he wanted to know why plants and animals have roughly the same number of genes as they do. This led him to create a model organism (a roundworm species) that scientists could use to study how these processes work. 

This roundworm has been used extensively by other researchers since then.  His model organism for development helped spur new research in this area of science.

Additionally, Brenner was jointly awarded the Nobel Prize in Medicine or Physiology in 2002 for his contributions to understanding how genes function during development.

What’s the best Sydney Brenner quote?

“Progress in science depends on new techniques, new discoveries and new ideas, probably in that order.”
