I am a creationist and an evolutionist. Evolution is God's, or Nature's method of creation. Creation is not an event that happened in 4004 BC; it is a process that began some 10 billion years ago and is still under way.
Theodosius DobzhanskyRead
Evolutionary plasticity can be purchased only at the ruthlessly dear price of continuously sacrificing some individuals to death from unfavourable mutations. Bemoaning this imperfection of nature has, however, no place in a scientific treatment of this subject.
Interpretation
Evolution relies on the survival of the fittest, often requiring sacrifices due to unfavorable mutations.
This quote by Theodosius Dobzhansky emphasizes the harsh realities of evolutionary processes, where the adaptability and diversity of species come at the cost of the survival of some individuals who bear unfavorable mutations. While it may seem tragic to sacrifice certain lives, this is an essential part of natural selection and evolution, and lamenting this fact does not advance scientific understanding.
In practice
In a lecture on evolutionary biology, I used this quote to illustrate the harsh realities of natural selection.
I am a creationist and an evolutionist. Evolution is God's, or Nature's method of creation. Creation is not an event that happened in 4004 BC; it is a process that began some 10 billion years ago and is still under way.
Nothing in biology makes sense except in the light of evolution.
It is hardly possible to maintain seriously that the evil done by science is not altogether outweighed by the good. For example, if ten million lives were lost in every war, the net effect of science would still have been to increase the average length of life.
It is always good to know which ideas cannot be checked directly, but it is not necessary to remove them all. It is not true that we can pursue science completely by using only those concepts which are directly subject to experiment.
If the tribal peoples actually represented Western origins at a much earlier time, it was exceedingly valuable that they should be studied intensely for clues about the nature and origin of human society. Consequently it was an injury to science and human knowledge to allow the military to simply exterminate them.
And I don't care what else anyone has ever told you, the Sun is white, not yellow. Human color perception is a complicated business, but if the Sun were yellow, like a yellow lightbulb, then white stuff such as snow would reflect this light and appear yellow-a snow condition confirmed to happen only near fire hydrants.
Science is a way of getting knowledge. It's a method. It's a method that really relies on making mistakes. We propose ideas, they are usually wrong, and we test them against the data. Scientists do this in a formal way. It's a way that everyone can go through life; that's how we should be teaching science from a very young age.
The internal machinery of life, the chemistry of the parts, is something beautiful. And it turns out that all life is interconnected with all other life.
