Quotes About Biology

The first way that selection can cause ageing is to keep early-acting mutations rare in populations, while allowing ones with effects late in life to become common.

Thoughts, feelings, hopes and dreams exist on Earth because of electrical activity inside a 1.5-kilogram blob of stuff, which hasn't changed much since the earliest modern humans began the long journey out of Africa

Lucy was little more than an upright chimpanzee; an animal, a genetic survival machine. We bring art, science, literature and meaning to the Earth; we are a world away, and yet separated by the blink of an eye.

Il nous faut partir d'une conception d'ensemble de l'organisme en tant qu'une entité fondamentale de la biologie, puis comprendre comment celui-ci se divise en parties qui respectent son ordre intrinsèque - pour donner un organisme harmonieusement intégré en dépit de sa complexité.

The Biology of Hope and the Healing Power of the Human Spirit

One of the most famous aphorisms in science is the British biologist J. B. S. Haldane's answer to the question, What might one conclude about God based on a study of His creation? "An inordinate fondness for beetles.

You take bits off crickets and they grow new parts," Edwards explains in his cheery New Zealand accent. "My interest in this alpine work is that you find creatures growing in habitats where you wouldn't expect anything to be.

What we call "cuteness" is actually an evolutionary adaptation that helps ensure that parents will care for their children, that babies will get their needs met, and that parents will take on this seemingly thankless task with pleasure.

Childhood experiences literally impact the biology of the brain.

If you look carefully at our biology after a traumatic experience-all the way down to the way genes are expressed-trauma will change everyone in some way.

Biyoloji sadece deÄŸiÅŸtirilmeyen bir senaryoyu oynayan genlerden ibaret deÄŸildir. Evrimsel süreçlerde olduÄŸu gibi etraftaki dünyaya kar?? da duyarl?d?r.

You may consider yourself an individual, but as a cell biologist, I can tell you that you are in truth a cooperative community of approximately fifty trillion single-celled citizens.

I knew I was going to be a cellular biologist whose research would focus on scrutinizing every nuance of the cell's ultrastructure to gain insights into the secrets of cellular life.

So one way of looking at our trillion-celled bodies is that they are protein machines, although, as you know, I think we are more than machines! It sounds simple, but it isn't. For one thing, it takes over 100,000 different types of proteins to run our bodies. Let

school you may have learned the basic components of a cell: the nucleus that contains genetic material, the energy-producing mitochondria, the protective membrane at the outside rim, and the cytoplasm in between.

Nathanielsz is one of the scientists now brave enough to invoke the "L" word for Lamarck: "the transgenerational passage of characteristics by nongenetic means does occur. Lamarck was right, although transgenerational transmission of acquired characteristics occurs by mechanisms that were unknown in his day.

Cells, tissues, and organs do not question information sent by the nervous system. Rather, they respond with equal fervor to accurate life-affirming perceptions and to self-destructive misperceptions. Consequently, the nature of our perceptions greatly influences the fate of our lives.

True" scientists consider anthropomorphism to be something of a mortal sin and ostracize scientists who knowingly employ it in their work.

No matter how you cut it, biological science is based to some degree on humanizing the subject matter.

epigenetics, a booming field of biology that is unraveling the mysteries of how the environment influences the behavior of cells without changing the genetic code.

The polarized outer cells are destined to become trophoblast, whereas those cells located in the interior are destined to become the inner cell mass, from

DNA is the messenger which illuminates that connection,handed down from generation to generation,carried,literally,in the bodies of my ancestors.
