Hypothesis Quotes
-
Nevertheless, as is a frequent occurrence in science, a general hypothesis was constructed from a few specific instances of a phenomenon.
-
The results serve to disprove the tetranucleotide hypothesis. It is, however, noteworthy-whether this is more than accidental, cannot yet be said-that in all desoxypentose nucleic acids examined thus far the molar ratios of total purines to total pyrimidines, and also of adenine to thymine and of guanine to cytosine, were not far from 1.
-
Hypotheses are lullabies for teachers to sing their students to sleep.
-
It is more than likely that the brain itself is, in origin and development, only a sort of great clot of genital fluid held in suspense or reserved. This hypothesis would explain the enormous content of the brain as a maker or presenter of images.
-
Darwin and his successors have railed against the fallacy of confusing the current utility of a trait with the reason the trait evolved. For example, Darwin argued that skull sutures in mammals did not evolve because they facilitate live birth; the sutures were in place well before live birth evolved. Checking the chronological order in which different traits evolved in a lineage is one way to test an adaptive hypothesis; the fact of common ancestry is what makes that checking possible.
-
One must treat theory-in-use as both a psychological certainty and an intellectual hypothesis.
-
That's how the scientists discover new science. They start out with a hypothesis--an idea--and then others believe enough in the idea that they make it true. You see?
-
There is the theory that all the living forms in the world have arisen from a single source which itself came from an inorganic form. This theory can be called the 'general theory of evolution,' and the evidence which supports this is not sufficiently strong to allow us to consider it as anything more than a working hypothesis.
-
Science is advanced by proposing and testing hypothesis, not by declaring questions unsolvable.
-
Current organisms have a higher probability of sharing a single code if the common ancestry hypothesis is true than they'd have if the hypothesis of separate ancestry were true. That is, the simpler hypothesis has the higher likelihood in the technical sense of "likelihood" used in statistics.
