If it's hereditary, then the mutation has been hidden from us for, like, maybe even hundreds of thousands of years.
Thus arose the system of " initial mutation ": an initial consonant may retain its original form, or may undergo any of the changes to which it is subject.
The spirant mutation occurs after a, " and," " with," ei, " her "; thus a phen, " and a head," ei phen, " her head."
Although the original mutation was not caused by human activity, human activity preserved and perpetuated it.
As then the Ent is one, invariable and immutable, all plurality, variety and mutation belong to the Nonent.
This varying rate of evolution has (illogically, we believe) been compared with and advanced in support of the "mutation law of De Vries,"or the theory of saltatory evolution, which we may next consider.
Her Mutation de fortune, in which she finds room for a great deal of history and philosophy, was presented to the same patron on New Year's Day, 1404.
The nasal mutation occurs after fy, " my," and yn, " in "; thus fy mhen, " my head " (pen, " head "), yn Nhalgarth, " at Talgarth."
By some writers the word " mutation " is applied only to large and suddenly appearing variations which are found to be capable of hereditary transmission, whilst the term " fluctuation " is applied to small variations whether capable of transmission or not.
The collective term " mutation," as now employed by palaeontologists, signifies a type modified to a slight degree in one or more of its characters along a progressive or definite line of phyletic development.
Hence the theory of the unity of nature is necessarily followed by a theory of its seeming plurality, that is to say, of the variety and mutation of things.
The term " mutation " also applies to a single new character and for distinction 1 may be known as " the mutation of Waagen."
It is certainly a very striking fact that wherever we have been able to trace genetic series, either of invertebrates or vertebrates, in closely sequent geological horizons, or life zones, we find strong proof of evolution through extremely gradual mutation simultaneously affecting many parts of each organism, as set forth above.
Here, if we attend to the effect of the whole revolution, we shall find that the electric states of the respective masses have been greatly increased; for the ninety-nine parts in A and B remain, and the one part of electricity in C has been increased so as nearly to compensate ninety-nine parts of the opposite electricity in the revolving plate B, while the communication produced an opposite mutation in the electricity of the ball.
And I won't share how to counter her mutation so you don't end up at Sasha's feet.
This revolution may be accomplished by adding the term " mutation ascending " or " mutation descending " for the minute steps of transformation, and the term phylum, as employed in Germany, for the minor and major branches of genetic series.
