Are all changes in behaviour due to experience

Yes all changes in behaviour are due to experience because learning is in
effect, a change in behavior due to changes in the environment.
Gordon's study of guppies
Give this one a try later!
, Gordon studied guppies, they were put into a stream where they were
exposed to new predators. The guppies did adapt, however it took
between 13 and 26 generations. Guppies are short lived and this
experiment took eight years. Most other species take longer to fully
mature.
genetic engineering (gene splicing)

Researchers are able to isolate the strains of genes
Why do modal action patterns (MAP) contribute to the survival of a species?
Give this one a try later!
MAPs that are modal action patters such as migration and mating rituals, if
the environment changes the species modal action pattern does not. Take
in consideration of a salmon swimming up stream to mate. The salmon must
swim against currents and ascend steep cliffs. At one point the geological
changes gradually increased the steepness of the slope. If the salmon
could not make the slope it could not reproducer meaning there is a
natural selection of the salmon who can. Therefore their own modal action
pattern is affects their survival.

mutation and natural selection

Sometimes we have abrupt changes in genes, these are called mutations.
Almost all mutations do not help the survival, sometime they do prove
useful. Mutations affecting a nation is not likely to occur.

all participants are exposed to every treatment or condition. The treatment
is used to describe that different levels of the independent variable, the
variables that is controlled by the experimenter.
