of organisms were of central importance. As Francis Huxley has pointed out, Darwin’s most famous book could more appropriately have been entitled The Origin of Habits.
Morphic Fields and Morphic Resonance
by Rupert Sheldrake
In the hypothesis of formative causation, discussed in detail in my books A New Science of Life and The Presence of the Past, I propose that memory is inherent in nature. Most of the so-called laws of nature are more like habits.
My interest in evolutionary habits arose when I was engaged in research in developmental biology, and was reinforced by reading Charles Darwin, for whom the habits
Over the course of 15
years of research on plant development, I came to the
conclusion that for understanding the development of
plants, their morphogenesis, genes and gene products are
not enough. Morphogenesis also depends on organizing
fields. The same arguments apply to the development of
animals. Since the 1920s many developmental biologists
have proposed that biological organization depends on
fields, variously called biological fields, or
developmental fields, or positional fields, or
morphogenetic fields.
All cells come from other cells, and all cells inherit
fields of organization. Genes are part of this
organization. They play an essential role. But they do not
explain the organization itself. Why not?
Thanks to molecular biology, we know what genes do. They
enable organisms to make particular proteins. Other genes
are involved in the control of protein synthesis.
Identifiable genes are switched on and particular proteins
made at the beginning of new developmental processes. Some
of these developmental switch genes, like the Hox
genes in fruit flies, worms, fish and mammals, are very
similar. In evolutionary terms, they are highly conserved.
But switching on genes such as these cannot in itself
determine form, otherwise fruit flies would not look
different from us.
Many organisms live as free cells, including many yeasts,
bacteria and amoebas. Some form complex mineral skeletons,
as in diatoms and radiolarians, spectacularly pictured in
the nineteenth century by Ernst Haeckel. Just making the
right proteins at the right times cannot explain the
complex skeletons of such structures without many other
forces coming into play, including the organizing activity
of cell membranes and microtubules.
Ernst Haeckel Tafel 06
Most
developmental biologists accept the need for a holistic or integrative
conception of living organization. Otherwise biology will go on floundering,
even drowning, in oceans of data, as yet more genomes are sequenced, genes
are cloned and proteins are characterized.
I suggest that morphogenetic fields work by imposing patterns on otherwise
random or indeterminate patterns of activity. For example they cause
microtubules to crystallize in one part of the cell rather than another,
even though the subunits from which they are made are present throughout the
cell.
Morphogenetic fields are not fixed forever, but evolve. The fields of Afghan
hounds and poodles have become different from those of their common
ancestors, wolves. How are these fields inherited? I propose that that they
are transmitted from past members of the species through a kind of non-local
resonance, called morphic resonance.
The fields organizing the activity of the nervous system are likewise
inherited through morphic resonance, conveying a collective, instinctive
memory. Each individual both draws upon and contributes to the collective
memory of the species. This means that new patterns of behaviour can spread
more rapidly than would otherwise be possible. Foe example, if rats of a
particular breed learn a new trick in Harvard, then rats of that breed
should be able to learn the same trick faster all over the world, say in
Edinburgh and Melbourne. There is already evidence from laboratory
experiments (discussed in
A
New Science of Life)
that this actually happens.
The resonance of a brain with its own past states also helps to explain the
memories of individual animals and humans. There is no need for all memories
to be “stored” inside the brain.
Social groups are likewise organized by fields, as in schools of fish and
flocks of birds. Human societies have memories that are transmitted through
the culture of the group, and are most explicitly communicated through the
ritual re-enactment of a founding story or myth, as in the Jewish Passover
celebration, the Christian Holy Communion and the American thanksgiving
dinner, through which the past become present through a kind of resonance
with those who have performed the same rituals before.
The Memory of Nature
From the point of view of the hypothesis of morphic resonance, there is no
need to suppose that all the laws of nature sprang into being fully formed
at the moment of the Big Bang, like a kind of cosmic Napoleonic code, or
that they exist in a metaphysical realm beyond time and space.
Before the general acceptance of the Big Bang theory in the 1960s, eternal
laws seemed to make sense. The universe itself was thought to be eternal and
evolution was confined to the biological realm. But we now live in a
radically evolutionary universe.
If we want to stick to the idea of natural laws, we could say that as nature
itself evolves, the laws of nature also evolve, just as human laws evolve
over time. But then how would natural laws be remembered or enforced? The
law metaphor is embarrassingly anthropomorphic. Habits are less
human-centered. Many kinds of organisms have habits, but only humans have
laws. The habits of nature depend on non-local similarity reinforcement.
Through morphic resonance, the patterns of activity in self-organizing
systems are influenced by similar patterns in the past, giving each species
and each kind of self-organizing system a collective memory.
I believe that the natural selection of habits will play an essential part
in any integrated theory of evolution, including not just biological
evolution, but also physical, chemical, cosmic, social, mental and cultural
evolution.
Habits are subject to natural selection; and the more often they are
repeated, the more probable they become, other things being equal. Animals
inherit the successful habits of their species as instincts. We inherit
bodily, emotional, mental and cultural habits, including the habits of our
languages.
Fields of the Mind
Morphic fields underlie our mental activity and our perceptions, and lead to
a new theory of vision, as discussed in The Sense of Being Stared At.
The existence of these fields is experimentally testable through the sense
of being stared at itself. You can take part in a staring experiment
yourself through this website.
