It is well known that termites display adaptive social behavior under varying environmental conditions. Different types of individuals (i.e., castes) show distinctive phenotypes specialized in specific colony tasks. The whole colony is coordinated by interactions among colony members.2
Below are key findings, organized by time of discovery.
Week 1:
The NLML system identified over 2000 “words” of the
termite’s language where individual words were either pure sounds, electrical
signals, pheromones, or combinations of these elements.
The system also mapped the morphology of the language.
The language displayed all the features of a combinatorial communication system
where two or more signals are combined to produce an effect that neither signal
alone can produce. Combinatorial communications systems are associated with
higher species, but this may represent another possible exception5
Week 2:
The cyberMites located in the nursery were
the first to successfully mimic the termite language6. Soon, all
cyberMites were able to communicate with other colony members.
Week 3:
By analyzing conversations (i.e., the exchange of
messages between termites) the investigators were able to identify several new
castes and caste interactions:
(a) Fact-caste:
Termites in this caste talked exclusively about facts and the history of events
related to the colony. For example, they knew the temperature of the nest
currently as well as any past day of the year. They would reply to questions from any cyberMite
but only if the
question called for a factual answer.
(b) Analyst-caste:
Those in this caste responded only to questions about the future or about the
probability of occurrence of some event. For example, if a member of the
fact-caste gave an analyst-termite the current population of the colony, the
current birth rate (about 30,000/day) and the current death rate, that analyst
would give the estimated population of the colony for any given future day. For the most part estimates from
different analyst-termites were in fairly close agreement.
(c) Policy-caste: Those
in this class only responded to questions about
what future action
should be taken when they were given a consensus prediction from the
analyst-caste. For example, if the consensus prediction supported a high
likelihood of a food shortage, a member of the policy caste would offer a set
of actions aimed at increasing the future food supply. Policy answers from
different analyst-termites were often in close agreement, but sometimes they
were far apart. Continuing the above example, a second policy analyst might
recommend reducing the birth rate rather than increasing the food supply. Only
consensus positions were brought to the Queen, who would then instruct the soldier-caste to carry out the
policy.
It was observed that neither peer pressure, nor other
castes, nor the Queen would withhold (or grant) resources or services to any
policy-caste member based upon the policies offered by that member. Members of
the policy-caste would change their positions but only when presented with
sufficient facts and logic.
Week 8:
Members of the fact-caste were routinely asked about the
state of the nest. Recent answers suggested the overall health of the nest was
declining. Temperature, birth rates, and food supplies were on a slow downward
trend. Several analyst-caste members asked for more details before making
policy recommendations. One previously unreported detail emerged. In the past
30 days, the period length of the nest orbit had decreased in length by about
0.2%. After further inquiries to the fact-caste it was discovered the decrease
in period length could be traced back over a long duration of at least three
Queen generations (about 70 years).
Weeks 9 to 12:
Many analysts estimated the nest would, within the near
future, cease to swing. There was a growing consensus over the assumption that
the decreasing swing length was the primary cause
of the overall decline in the health of the nest. The
analysts were not in agreement about how to fix the decreasing swing length.
The fact-termites showed there was a strong correlation between the increasing
mass of the nest and the decrease in the swing period. Some analysts suggested
the period could be corrected by reducing the mass of the nest (the
“massites”).
Other analysts suggested altering the length of the vine
that secured the nest to the cave ceiling would correct the period. These
analysts were called “lengthites”.
Week 13:
A third group among the policy-termites emerged. They did
not deny the facts, but they did not agree with the assumptions that (a) the
primary cause of the decline in nest health was due to decreasing period length
and (b) changing either the period length or the nest mass would return the
nest to health. They argued that their opponents were basing their policies on
correlations, not causes and moreover there was insufficient evidence to
warrant causal conclusions. The policy advocated by this group was to abandon
the nest and establish a new colony elsewhere. This third group was called
“migrators”.
Week 20:
After intense and widespread conversations no consensus
between the three groups had emerged. Without a consensus nothing could be
presented to the Queen and no corrective actions would be taken. The Queen was
growing impatient. The policy-caste decided that each group should look deeper
into the implications of their recommended policies and report their findings
to all members of the policy community.
(1) The massites
reported their calculations showed that even with up to a 50% reduction
or 50% increase in nest mass, changes in period length, if any, would be
temporary. Eventually, the nest would cease to
swing.
(2) The
lengthites reported their calculations showed similar results. Neither up to a 50% reduction nor 50% increase in vine
length would result in permanent period length changes. Eventually, the nest
would cease to swing.
(3) The
migrators reported there were no suitable locations within a reachable distance
from the current nest. Any migration of the nest would have low probability of
success. In addition, only the Queen and a few soldiers would be able to
attempt the risky journey. Once the Queen
left the nest there would be
no new children. The entire
remaining colony would
perish in a matter of weeks.
Week 22:
A small number of policy-termites suggested a way to restore the orbit and presumably restore the nest’s health, was to apply an outside force to the nest. They felt safe in ignoring possible orbital variations such as any eccentricity of the nest's orbit or any precession or tilt of its rotational axis. They proposed attaching a second vine to the nest. The new vine would loop over a horizontal outcrop at a point many feet away from the current anchor point. At the far end of the new vine they would build an enclosure to hold the weight of many rocks. Once the added rocks moved the nest to greater than a 60° angle, the new vine would be detached from the nest. There was debate over the angle to be achieved before detaching the new vine. If too small, it might have little effect. If too great, it might jolt the nest and cause irreparable damage, or worse, it might sever the original supporting vine. After further analysis it was agreed that the angle should be 57.4°.
This “outside force policy” gained rapid acceptance. It was presented to and approved by the Queen.
Week 30:
Work on the new vine was completed. Rocks were added to
the enclosure until the desired release angle was achieved. The new vine was
detached. The period length was 52 feet, the same period length that was
recorded 10 Queen-lifetimes ago.
Weeks 40-60:
Temperatures are improving and the health of the nest is on an upward trend. So far, the outside force policy had resulted in a successful "great reset". It remains to be seen if this trend will continue.
=================================
Questions: Before answering you may wish to refresh your knowledge about Earth's energy budget here.
(1)
Talking
into account all orbital variations (i.e., the eccentricity of Earth's orbit
around the sun, the precession, and tilt of its rotational axis), does there
exist one or more orbital variations that would change Earth's Climate trend to
one more favorable than our current trend. If so, in what feasible ways could
any of these more favorable variations be achieved?
(2) Freeman Dyson Suggested that an advanced extra-terrestrial civilization might obtain energy by enclosing a star inside a sphere. A less ambitious effort for us would be to launch “umbrellas” that block the sun’s radiation from reaching parts of the earth. These could be put into geostationary orbit over the North and South poles. Is this a feasible and economical way to impact climate change?
