Easy. I make the case that you really can't understand the host side of
memetics without evolutionary psychology.

Dawkins argued that memes are elements of culture, like that streets are
dangerous places to play or how to make shoes or chipped rocks. I don't
know what you mean by "social life" in this context. If asked, I would say
that social life is the interactions of social primates. Social customs
are memes and determine the details of social life, such as forms of
greeting and dress. But social life itself is more related to basic social
primate drives (such as seeking status) than it is to replicating elements

EP does make the case that our psychological *traits* were shaped by what
worked to get genes into the next generation in the typical environment of
100,000 to a million years ago. That much you have right. But how such
things as the drive for status gets expressed is highly dependant on non
genetic facts, particularly the physical environment and social history of
a local group. To put it graphically, an !Kung and a Princeton graduate
have rather different ideas of what they need to do to obtain high status.

Genes built brains elaborating on the mammal/primate traits of being able
to learn a *lot.* At some point in the remote past our social primate
ancestors began to pass down learning--culture--from generation to
generation. It was particulate learning such as how to bash rocks and make
sharp edges. I have been reading a lot of Jane Goodall lately. By human
standards chimps don't have much culture, but they do have enough to
benefit their genes in a feedback loop.

Memes, like genes and computer viruses, are replicators, but they are of an
entirely different order than genes. Genes are strings of information in
DNA, instructions for to make the chemicals that construct living
creatures. Memes are the information that can be used to program the
brains of some of those living creatures so they can chip rocks and build
As to where memes came from, there is a better fossil cultural record than
we have of the very earliest days of biological evolution.
About 2.6 million years ago hominid groups with brains about the same size
as chimps were living in Africa. They left massive evidence (article I was
reading last week but can't find now) that they were making sharp edges by
breaking stones. From the butchering cut marks left on bones in the same
deposits, it is clear they were eating a lot of meat with the help of those
As to how the first sharp edged rock came from, we can only speculate. It
is known that chimps throw rocks and that the hominids who went out into
the grasslands for the previous million years carried rocks, possibly to
drive predators off kills or to keep big cats from making a meal of 4 foot
hominid or both.
Throwing stones, "manuports" are found in places where hominid transport
from distant rock outcrops is the most likely reason they are found (Mary
Leakey). As to why the hominids ventured out from the trees, it was
probably for meat. (Chimps *really* crave meat (Jane Goodall) and there is
no reason our remote ancestors didn't also.) They were probably killing
and eating young antelopes, same as baboons do today.
Given a million years, one of those thrown rocks would have hit something
hard and broken. Chimps can figure out the use of shape edges to cut down
a reward. The can learn to smash rocks on hard surfaces to make the sharp
edges. Some researchers found this out when they tried to teach a chimp to
chip rocks and the chimp persisted in making sharp fragments by smashing
his stones on the concrete floor (rather than on another rock).
Some chance observation by a bright hominid that her recovered but now
broken in half "lion stone" was useful in hacking off a chunk of a large
carcass the group chanced upon during the walk back to the trees where they
were sleeping seems to have been enough to start the evolution of our
entire meme based material culture. (This is a petrocentric view of
course. The bag might have been an important meme too but the supporting
evidence didn't survive.)

That's a good point. If the above isn't enough evidence for the start of
meme evolution and you want me to fill in web sites and book sources
supporting this view, let me know.
