Confused over Porcupine, Hedgehog, Echidna similarity and parallel evolution of novel coronavirus
One can learn a lot about RNA virus, their evolution,
infectivity, spontaneous disappearance of several RNA viruses, the repository
or inventory stock status of several RNA viruses in nature - domestic/wild
animals etc., in the research article entitled “The diversity of human RNA
virus” by Mark, Woolhouse and Adair from Centre for immunity,
infection, evolution, University of Edinburgh, the research work published in
the journal Future virology.
Viruses are supposedly the first form of life (living-no-
living character sharing organism) and the RNA viruses are more rapid than DNA
viruses in mutation. Whether the strain of novel coronavirus reported
from Wuhan, China is the one that spreads throughout or world or different
strains of novel coronaviruses have evolved in different parts of the world
under the process of evolution called ‘parallel evolution’ is a million
dollar question.
We cannot deny such
possibility because the virus that emerged in one country and supposedly from
animal source cannot thrive so successfully in all geographic conditions and
population. The virus mutating according
to the local conditions means then the virus need not have emerged from single
source…..
We cannot comment on how such sub-microscopic organism would
have got the stimuli simultaneously for parallel evolution in different
geographic regions but our inability in case does not rules out such possibility. Our ignorance cannot be an excuse to deny
such possibility.
Some of the best examples for animals that had followed
parallel evolution with reference to certain anatomical characteristics in
nature are, Porcupine, Hedgehog and Echidna; and all these animals have their hair
modified as spine or thorny appendage for self-defense.
Batesian and Mullerian mimicry of several unrelated species such
as coral snake, scarlet king snake, hawk moth etc., are best examples for how
certain ‘similar’ evolution and adaptations can be advantageous to different
animals and that happens even in dissimilar species.
The question is how the non-poisonous scarlet king snake has
learned to evolve and appear/ looks like poisonous coral snake so that it can
easily ward off its predators or vice versa, where the poisonous coral snake
will be seen as non-poisonous due to its appearance similarity with
non-poisonous scarlet king snake remains a mystery? On the contrary, why should
most of the poisonous mushrooms and the dart frog appear so attractive?
Aposematic phenomenon
of the novel coronavirus and the anaphylactic reaction of our lung cells or our
immune defence system leading to cytokine storm (as cytokine storm is reported to
be one of the leading causes of death in COVID 19) can we deny from existence.
If the above possibilities are true, then how every
individual in the population in different geography would exhibit same degree
of reaction to novel coronavirus? Then should
we not consider the manifestations of COVID 19 is more due to the host specific
issues where the contribution of the virus
may be miniscule and hence chasing the novel coronavirus and imposing shutdown
the entire country for indefinite period of time and thereby we can eliminate
the virus and virus induced death is a myth and foolish act?
Are we mixing porcupine to hedgehog and hedgehog to be
Echidna……. and vice versa due to some anatomical similarity?
If we go by the ‘spine’ similarity in all the above animals,
in all likelihood we may end up in saying all animals look similar to our ‘lay
eyes’. But they are totally different
and distinct. Even at behaviour level,
none of the above three animals would ever exhibit any similarity.
Is such ‘science wonder’ happening in the case of novel
coronavirus also, across the world? Are we trying to fit everything that we
observe into one frame that already we have created or manufactured?
The pathogenicity or virulence of the novel coronavirus
strain in India may be the least than the one that is prevalent in EU countries
and US.
It is like Koala that eats Eucalyptus leaf and lives in
Australia while Panda had occupied bamboo thicket ecosystem in sub Himalayan
region by eating bamboo leaves. From the objective perspective, both these
animals are herbivores, eat leaves, partly and or strictly arboreal, slow
movers but still they are totally different.
Koala cannot survive with bamboo leaves nor Panda with Eucalyptus
leaves? Herbivore exchange in different
habitat may not support either of the animals.
Are we complicating the basic, elemental truths in novel
coronavirus pandemic with the sophisticated science called genetic sequencing,
molecular biology based understanding etc.?
Are we missing the most
visible by way of searching out the invisible? The basic element of biology and evolution,
are we not negating to understand more about novel coronavirus?
We scared our
population beyond retraction about coronavirus pandemic and COVID 19.
Like a horror movie
show or the conjuring, our electronic and print media houses were competing
with each other to report various facets of coronavirus to people on hourly
basis.
Unfortunately we portrayed novel coronavirus as villain and
at the same time as hero and caused confusion, even to the virus.
Today many least educated people also have started to raise
doubts over the existence of novel coronavirus!
The extent of scare created by us was so high but fortunately in
proportion to the fear created by us, rate of death due to COVID 19 is very low
in India.
Should we credit our medical fraternity for the above or the kindness
of YAMA the Lord of death or the inability of novel coronavirus to harm Indians
or the enormously high immune surveillance of Indians, difficult answer?
Our medical fraternity is known to cause scare. Only from fear and ignorance of the patients,
they can harvest their crop (not all).
But today it looks like the fear and scare over novel coronavirus is giving diminishing returns.
It is purely due to the
senseless lockdown measure followed by Modi.
The lockdown has killed life and livelihood of millions and millions of
people. The economic disaster is looming
larger over our country than corona pandemic.
It is quite clear that novel coronavirus is not that all
strong and dominant in India and hence it has caused least trouble. But the lockdown has destroyed our
economy. People of India elected Modi
with astounding majority and made him decisive and authoritarian leader. Today the same decisive, democratically
elected majoritarian government is giving diminishing returns to the people who
elected.
India needs a weak,
coalition government to save our democracy and federal structure. India is not matured for single party rule is
the cardinal message coronavirus has taught Indians.
As long as novel
coronavirus remains in our memory, as long as the economic disaster continues,
people will remember the important political message that coalition government
alone can save India and not the government lead by a political party with
absolute majority.
Due to the vast
diversity and pluralistic nature of India, weakness is our real strength and
not eternal stability or super-dominant leadership or authoritarianism.
