I assume you're refering to Sheldrake. "Morphic resonance" is strictly a
theory of memory. As an embryo your development is guided by resonance with
previous embryos of your species. As an adult your morphology is stabilized
in part by resonance with yourself in the past. Resonance is a temporal
concept. You don't resonate across space; you resonate over time. To be
connected with someone across space entails a field. So if your dog senses
when you're on your way home, this is because you and your dog are embraced
within a single field. There's no resonance involved except that the field
itself resonates with past, similar fields. That's the theory, anyway.

As you know, Sheldrake has a lot to say about the blue tits. Here's an
excerpt from The Presence of the Past (1988) pp 177-178:
"The best-documented example of the spontaneous spread of a new habit
concerns the opening of milk bottles in Britain by birds...
"The first record of this habit was from Southampton in 1921, and its spread
was recorded at regular intervals from 1930 to 1947. It has been observed
in eleven species, but most frequently in great tits, coal tits, and blue
tits. Once discovered in any paticular place, the habit spread locally,
presumably by imitation.
"Tits do not usually venture more than a few miles from their breeding
place, and a movement of as much as fifteen miles is exceptional. Hence new
appreances of the habit more than fifteen miles from where it had previously
been recorded probably represented new discoveries by individual birds. A
detailed analysis of the records showed that the spread of the habit
accelerated as time went on, and that it was independently discovered by
individual tits at least 89 times in the British Isles.
"The habit also appeared in Sweden, Denmark, and Holland. The Dutch records
are particularly interesting. Milk bottles practically disappeared during
the war and became reasonably common again only in 1947 or 1948. Few if any
tits that had learned the habit before the war could have survived to this
date, but nevertheless attacks on bottles began again rapidly, and it seems
certain that the habit was started in many different places by many
What's interesting is first that the independent discovery of the
bottle-opening method accelerated over time and second that it picked up
again so quickly after being eliminated due to an absence of milk bottles.
Unlike the apocryphal story of the "100th monkey," this is a documented
example of widespread adoption of a new habit once it had spread to enough
members of that species. Without a field concept, there's no way of
explaining the acceleration of the tendency. Why doesn't it spread at
roughly the same rate over time? And why should it be taken up the second
time around so much more rapidly than the first?
This greatly complicates memetics. A cultural tendency could spread as a
result of imitation, or it might spread as a result of the members of a
species being embraced within a single Jungian-like field. This field would
of course be an extension of standard developmental fields. The field
concept, which is so important in explaining the development of individual
organisms, can also be applied to groups of organisms. That termites build
mounds is really no different than cells building lungs. Termite mounds
are, after all, essentially lungs, conveying oxygen to individual termites
and releasing carbon dioxide as waste. There seems to be no means for
termites, which are blind, to be able to construct their complex mounds
without being guided by a developmental field. If termites why not birds?
And if birds why not humans?
