Quotes About Biology

Nothing in Biology Makes Sense Except in the Light of Evolution.

As regards the individual nature, woman is defective and misbegotten, for the active power of the male seed tends to the production of a perfect likeness in the masculine sex while the production of a woman comes from defect in the active power.

IndieBio's capital, facilities, and deep mentoring by a network of biotech-specific experts have the potential to spawn the Google, Facebook, and Instagrams of biology.

Our brains have been designed to blur the line between self and other. It is an ancient neural circuitry that marks every mammal, from mouse to elephant.

The genetic you and the neural you aren't alternatives to the conscious you. They are its foundations.

Your brain is built of cells called neurons and glia - hundreds of billions of them. Each one of these cells is as complicated as a city.

Neuroscience is now a very important research area in biology. We are now understanding a lot more about brains in babies, as well as children and adults.

I have to admit I was dismayed when I found out 'type A' refers to a category of risk for heart disease - I thought it was just a nickname my mom gave me!

The idea of going back to school and revising for exams would be hellish. As an actor, my form of revising is learning scenes, but to start going through biology, chemistry, and all of those sciences would be just a nightmare.

All complex life shares an astonishing catalogue of elaborate traits, from sex to cell suicide to senescence, none of which is seen in a comparable form in bacteria.

Well, biology is not only about genes and environment, but also cells and the constraints of their physical structure, which we shall see have little to do with either genes or environment directly. The predictions that arise from these disparate world views are strikingly different.

Our terminal decline into old age and death stems from the fine print of the contract that we signed with our mitochondria two billion years ago.

I will argue that energy has constrained the evolution of life on earth; that the same forces ought to apply elsewhere in the universe; and that a synthesis of energy and evolution could be the basis for a more predictive biology, helping us understand why life is the way it is, not only on earth, but wherever it might exist in the universe.

it's no mystery that all cells here on earth should be chemiosmotic. I would expect that cells across the universe will be chemiosmotic too.

Sex is far more widespread than seems reasonable.

In an average person, ATP is produced at a rate of 9 × 1020 molecules per second, which equates to a turnover rate (the rate at which it is produced and consumed) of about 65 kg every day.

Core metabolism has changed little in part because it was never powered down in its four-billion-year history. The genes are custodians of this flame, but without the flame life is – dead.

Once the little squirt has found a suitable home, it attaches itself soundly to the spot and then, needing it no longer, reabsorbs its own brain (a feat that arouses much admiration among university professors, Steve Jones quips).

I hope to persuade you that energy is central to evolution, that we can only understand the properties of life if we bring energy into the equation.

I will lay out a hypothesis – tell a coherent story – that connects energy and evolution.

was a world on which life emerged, 3,800 million years ago, perhaps animated by something of the restlessness of the planet itself.

there isn't a full consensus among experts. But strip away a few more skins from the onion of time and, by 3,400 million years ago

Bacteria dominated our planet for another 2,500 million years before the first truly complex organisms appeared in the fossil record.

Essentially all life uses redox chemistry to generate a gradient of protons across a membrane. Why on earth do we do that?
