Why would natural selection lead to Lysozyme, an antiseptic found in breast milk, to peak in
concentration from 6-15 months IF, like most doctors advise, mothers should stop breast feeding
after 6 months? That makes no sense from a evolutionary view point does it?
See the concentration of - Immunologic Components in Human Milk - chart.
Note the increase of Lysozyme peaking from 6-15 months. If true why would
people recommend ending breastfeeding at 6 months before the peak period. That would miss all the Lysozyme benefits.
Definition Lysozyme, " an enzyme with antiseptic actions that destroys some foreign organisms. It is found in granulocytic and monocytic blood cells and is normally present in saliva, sweat, breast milk, and tears."
Also note the 50 chemicals found in breast milk - these are not in formula.

You may have misunderstood something. Here is what one website, by

the La Leche League quotes in that connection:
The American Academy of Pediatrics currently (2005) recommends:
"Pediatricians and parents should be aware that exclusive
breastfeeding is sufficient to support optimal growth and development
for approximately the first 6 months of life and provides continuing
protection against diarrhea and respiratory tract infection.
Breastfeeding should be continued for at least the first year of life
and beyond for as long as mutually desired by mother and child."*
*See http://aappolicy.aappublications.org/cgi/content/full/pediatrics;115/2/496
excerpted from:
http://www.llli.org/faq/bflength.html
Note the distinction between "exclusive breastfeeding" in the first
sentence and "Breastfeeding" in the second.

You are in agreement with La Leche, whose webpage goes on to say [not
quoting from the AAP any more]:
All the benefits of human milk�including nutritional and
health�continue for as long as your baby receives your milk. In fact,
as your baby takes less human milk, these advantages are condensed
into what milk is produced. Many of the health benefits of human milk
are dose related, that is, the longer the baby receives human milk,
the greater are the benefits.

That's an important detail - but I have found that most sites recommend 6 months period. And they don't stress the idea that breast milk should continue after weaning for at least a year. I still would go further than these experts.
Personally I think that adding solids along with breast milk at 6 months is still too soon. I don't think the body is ready for solids. There are some biological clues - for instance the first tooth coming in around 7 months. I would think we humans have evolved to not eat solids till we have teeth, and that would take much more than 6 months.

Speaking of infant feeding, here are some thoughts on weaning and it's possible importance
Weaning off breast milk, may be a key development for a child. It helps him
'wean' himself from not only his mother's milk but anyone, become independent, and set up a system to recover from loss. Note the idea of separation anxiety in infants.
Those never breast fed, are never weaned, and may have dependency problems. They may not have the biological basis for a positive response to trauma.
First an infant has to respond to loss of breast milk trauma. Then as adults we have to respond to loss of breast milk type nurturing (loss of money, home, loved one, etc.) Weaning seems to give a biological basis to dealing with later trauma.

Can you direct me to some sites that quote from something as relevant

as the American Association of Pediatricians backing them up? Even
ACOG [the Ob-Gyn organization] doesn't seem quite as relevant.
In any event, I would like to see some of the sites you have seen so
far.

bananas at 6 months, and the usual "baby food" only a few months
later--none of it needing any teeth.
By the way, have comparisons been made between the digestive systems
of mammals and the digestive systems of birds that are fed
regurgitated food when young? Do those young have stones in their
gizzards early on?
