What does the ‘redundant’ 90% of DNA do?

The Human Genome Project, whilst aiming at identifying all the genes that influence the physical development of a human being, is according to some sources only concentrated on some 10 percent of the whole DNA strand.

The other 90 percent somehow must be capable of passing on more abstract characteristics and not merely ‘redundant’ as quoted in some books. I believe the Cuckoo is a prime example of this genetic behavior, able to be raised by foster parents, yet still act as a cuckoo, seek to mate with another and repeat the cuckoo cycle. On the human front, there has always been an argument over wether any ‘like father, like son’ observations were genetic or learnt traits, however there are now examples of Heart Transplant recipients displaying traces of their Donor’s behaviour. Though these instances were quite trivial in themselves, it does point to the body’s ability to encode habitual behavior in it’s DNA, and in these cases, for the Recipient’s body to de-code that. In other words, the DNA of a particular individual is actually dynamic rather than static, changing through it’s life span.

I would be interested to know what research has been made into the ‘redundant’ 90 percent of DNA.

How are galaxies speeding away from earth at 1 million meters per second? Why dont they look like they are moving that fast?
