Neil Shubin Quotes & Sayings

Imagine a house coming together spontaneously from all the information contained in the bricks: that is how animal bodies are made. — Neil Shubin

Over 99 percent of all species that ever lived are now extinct. — Neil Shubin

The immediate thing that strikes you when you see the inside of the hand is its compactness. The ball of your thumb, the thenar eminence, contains four different muscles. Twiddle your thumb and tilt your hand: ten different muscles and at least six different bones work in unison. Inside the wrist are at least eight small bones bones that move against one another. Bend your wrist, and you are using a number of muscles that begin in your forearm, extending into tendons as they travel down your arm to end at your hand. Even the simplest motion involves a complex interplay among many parts packed in a small space. — Neil Shubin

We were not designed rationally, but are products of a convoluted history. — Neil Shubin

The molecules that allow microbes to catch their prey and hold on to them are likely candidates for the molecules that form the rivet attachments between cells in our bodies. — Neil Shubin

Some people can detect the odor molecules in a green bell pepper at a concentration of less than one part per trillion. That is like picking out one grain of sand from a mile-long beach. — Neil Shubin

We were staring at the origin of a piece of our own bodies inside this 375-million-year-old fish. We had a fish with a wrist. — Neil Shubin

No sane paleontologist would ever claim that he or she had discovered "The Ancestor." Think about it this way: What is the chance that while walking through any random cemetery on our planet I would discover an actual ancestor of mine? Diminishingly small. What I would discover is that all people buried in these cemeteries
no mater whether that cemetery is in China, Botswana, or Italy
are related to me to different degrees. I can find this out by looking at their DNA with many of the forensic techniques in use in crime labs today. I'd see that some of the denizens of the cemeteries are distantly related to me, others are related more closely. This tree would be a very powerful window into my past and my family history. It would also have a practical application because I could use this tree to understand my predilection to get certain diseases and other facts of my biology. The same is true when we infer relationship among species. — Neil Shubin

All the genetic switches that make fingers, arm bones, and toes do their thing during the third to eighth week after conception. — Neil Shubin

Whole batteries of genes are turned on and off during fly development, and this
pattern of gene activity serves to demarcate the different regions of the fly. — Neil Shubin

With respect to the ZPA, what kind of digit develops depends on how close the digit is to the source of Sonic hedgehog. — Neil Shubin

At conception, we start as a single cell that contains all the DNA needed to build our body. The plan for that entire body unfolds via the instructions contained in this single microscopic cell. To go from this generalized egg cell to a complete human, with trillions of specialized cells organized in just the right way, whole batteries of genes need to be turned on and off at just the right stages of development. Like a concerto composed of individual notes played by many instruments, our bodies are a composition of individual genes turning on and off inside each cell during our development. — Neil Shubin

Tiktaalik has a shoulder, elbow, and wrist composed of the same bones as an upper arm, forearm, and wrist in a human. When we study the structure of these joints to assess how one bone
moves against another, we see that Tiktaalik was specialized for a rather extraordinary function: it was capable of doing push-ups. — Neil Shubin

[T]he unknown should not be a source of suspicion, fear, or retreat to superstition, but motivation to continue asking questions and seeking answers. — Neil Shubin

Each galaxy, star, or person is the temporary owner of particles that have passed through the births and deaths of entities across vast reaches of time and space. The particles that make us have traveled billions of years across the universe; long after we and our planet are gone, they will be a part of other worlds. — Neil Shubin

In a perfectly designed world - one with no history - we would not have to suffer everything from hemorrhoids to cancer. — Neil Shubin

But why live in these environments at all? What possessed fish to get out of the water or live in the margins? Think of this: virtually every fish swimming in these 375-million-year-old streams was a predator of some kind. Some were up to sixteen feet long, almost twice the size of the largest Tiktaalik. The most common fish species we find alongside Tiktaalik is seven feet long and has a head as wide as a basketball. The teeth are barbs the size of railroad spikes. Would you want to swim in these ancient streams? — Neil Shubin

Knowing something about the deep origins of humanity only adds to the remarkable fact of our existence: all of our extraordinary capabilities arose from basic components that evolved in ancient fish and other creatures. — Neil Shubin

We would never have scales, feathers, or breasts if we didn't have teeth in the first place. — Neil Shubin

When you see these deep similarities among different organs and bodies, you begin to recognize that the diverse inhabitants of our world are just variations on a theme. — Neil Shubin

In preparing for battle, I have found that planning is essential, but plans are useless. - Dwight D. Eisenhower — Neil Shubin

What is it about a hand that seems quintessentially human? The answer must, at some level, be that the hand is a visible connection between us; it is a signature for who we are and what we can attain. Our ability to grasp, to build, and to make our thoughts real lies inside this complex of bones, nerves, and vessels. — Neil Shubin

My building was constructed in 1896, and the utilities reflect an odd design that has been jerry-rigged further with each renovation. If you want to understand the wiring and plumbing in my building, you have to understand its history, how it was renovated for each new generation of scientists. My head has a long history also, and that history explains complicated nerves like the trigeminal and the facial. — Neil Shubin

When the finely tuned balance among the different parts of bodies breaks down, the individual creature can die. A cancerous tumor, for example, is born when one batch of cells no longer cooperates with others. By dividing endlessly, or by failing to die properly, these cells can destroy the necessary balance that makes a living individual person. Cancers break the rules that allow cells to cooperate with one another. Like bullies who break cooperative societies, cancers behave in their own best interest until they kill their larger community, the human body. — Neil Shubin

Take the entire 4.5-billion-year history of the earth and scale it down to a single year, with January 1 being the origin of the earth and midnight on December 31 being the present. Until June, the only organisms were single-celled microbes, such as algae, bacteria, and amoebae. The first animal with a head did not appear until October. The first human appears on December 31. We, like all the animals and plants that have ever lived, are recent crashers at the party of life on earth. — Neil Shubin
