People have always asked whether evolution is constantly driving onwards and upwards. Is there always going to be improvement? The answer is no: evolution is a progression of form and function, but it is not purposeful.

The thing I'm most interested in is the nervous system. How do brains grow? How do genes build complicated nervous systems?
Interpretation
This quote emphasizes the importance of understanding the nervous system and brain development.
Sydney Brenner expresses a deep interest in the complexities of the nervous system, highlighting the intricate relationship between brain growth and genetic influences. This reflects a broader curiosity in neuroscience and the fundamental biological processes that shape how organisms develop and function.
In practice
In a lecture on neuroscience, one might use this quote to illustrate the significance of brain development.
People have always asked whether evolution is constantly driving onwards and upwards. Is there always going to be improvement? The answer is no: evolution is a progression of form and function, but it is not purposeful.
The moment I saw the model and heard about the complementing base pairs I realized that it was the key to understanding all the problems in biology we had found intractable - it was the birth of molecular biology.
The art of doing science is doing the important things first.
As was predicted at the beginning of the Human Genome Project, getting the sequence will be the easy part as only technical issues are involved. The hard part will be finding out what it means, because this poses intellectual problems of how to understand the participation of the genes in the functions of living cells.
It is now widely realized that nearly all the 'classical' problems of molecular biology have either been solved or will be solved in the next decade. The entry of large numbers of American and other biochemists into the field will ensure that all the chemical details of replication and transcription will be elucidated. Because of this, I have long felt that the future of molecular biology lies in the extension of research to other fields of biology, notably development and the nervous system.
We need to start thinking about the future of food if we are going to feed 9 billion people in a way that does not destroy our environment.
One can get a proper insight into the practice of flying only by actual flying experiments. . . . The manner in which we have to meet the irregularities of the wind, when soaring in the air, can only be learnt by being in the air itself. . . . The only way which leads us to a quick development in human flight is a systematic and energetic practice in actual flying experiments.
[Science] is corrosive of religious belief, and it's a good thing too.
Science itself is badly in need of integration and unification. The tendency is more and more the other way ... Only the graduate student, poor beast of burden that he is, can be expected to know a little of each. As the number of physicists increases, each specialty becomes more self-sustaining and self-contained. Such Balkanization carries physics, and indeed, every science further away, from natural philosophy, which, intellectually, is the meaning and goal of science.
Chemistry... is like the maid occupied with daily civilisation; she is busy with fertilisers, medicines, glass, insecticides ... for she dispenses the recipes.
We carry stores of DNA in our nuclei that may have come in, at one time or another, from the fusion of ancestral cells and the linking of ancestral organisms in symbiosis. Our genomes are catalogues of instructions from all kinds of sources in nature, filed for all kinds of contingencies.
