This presentation will be about biological
rhythms, and most of the rhythmic
characteristics, that I'll be speaking
about have to do with daily rhythms.
that are exhibited by a fruit fly,
one of which is actually indicated
over there on the left, Drosophila.
The display here of a variety of
different kinds of daily rhythms,
is not done completely errantly.
Because several features, of the outcomes
of studying rhythms Drosophila,
were better than the investigators
intended in a way.
Because they spoke to certain
components or even several ones,
of rhythm control that are operating in
many other different kinds of organisms,
which is one of the pleasant surprises
involving studies of rhythmicity in
the fruit fly, Drosophila.
I and colleagues began,
looking into rhythms Drosophila
back in the late 1970s or so.
And this refers in a way to the fact that
this treatment of rhythms in Drosophila,
will have two attributes, one, that
it's gonna be largely based on genetics,
genetic variance, either mutants or
genetic variants that are made by
various molecular genetic manipulations.
Second, I'm largely going to be
treating this subject historically,
I will be flashing through many of
the pictures here without delving
all that deeply into the chronobiological
matter in question, but
mostly trying to give a survey of how
a genetic approach to studying rhythms,
notably daily ones,
how the genetic approach to these arguably
interesting biological problems,
came out very well and
revealed much in the way about,
how rhythms of this sort are regulated.
Not only in Drosophila as previewed,
but also in other organisms.
