That doesn't mean that it is a "memory bank" Just a repository for
turned off sequences. What turns them on again is a moot point.
Evolution isn't using these if needed, it is being lucky enough to
have a random mutation that confers a survival benefit. And when all
your non-mutated peers are dying from some environmental change
(antibiotics) , you will outcompete them.

But what if a mutation in the past had developed an ability to access the
junk DNA under stress? Would that be as complex as developing eyes
ears and advanced emotions by mutation?

What if some thing that are now blue turn green on August 5th, 2005 and we
have a new color bleen, blue that turns to green.

You stabbing in the dark about thing you have no knowledge of. Do you trust
propaganda machines more than scientist that spend their lives working in a
field?

I am not stabbing in the dark, I am trying to get Moosh:] thinking.

You're not going to convince anyone with propaganda and fringe
science, and wild speculation. You must become far more
discriminating.

Perhaps only 1% of the human genome codes for genes, and that's what
the human genome map contains. The rest is mainly repetitive DNA,
commonly known as `junk DNA'.

However, evidence has been emerging that lurking within junk DNA are
armies of transposons (mobile genetic elements) that play an
indispensable role in `natural genetic engineering' the genome. They
make up nearly half of the human genome, and serve as `recombination
hotspots' for cutting and splicing, and hence reshuffling the genome.
They are also a source of ready to use motifs for gene expression, as
well as new protein-coding sequences.

These important transposons are scattered throughout the genome. There
are two main categories: Long Interspersed Elements (LINEs) about 6.7
kilobasepairs in length and Short Interspersed Elements (SINEs) of
several hundred basepairs.

The most abundant SINEs are Alu elements, of which 1.4 million copies
exist, comprising 10% of the human genome, and are apparently only
found in primates.

[...]
There is increasing evidence that physical and chemical stresses to
the cell, such as heat shock, chemical poisons and viral infections,
tend to activate Alu elements. The resultant gene reshuffling may be
responsible for a variety of chronic diseases (see "Dynamic genomics
", this series).

Wild speculation. Perhaps a tiny truth here, but likely insignificant
in the washup.
