Everything about Konstantin Mereschkowski totally explained
Konstantin Sergejewicz Mereschkowsky (
1855-
1921) (
Russian: Константин Сергеевич Мережковский, also
transliterated Konstantin Sergeevich Merezhkovsky,
Konstantin Sergivich Merezhkovsky,
Constantin Sergeevič Mérejkovski,
Constantin Sergejewicz Mereschcowsky, and
Konstantin Sergejewicz Mereschkovsky) was a prominent
Russian
biologist and
botanist active mainly around
Kazan, whose research on
lichens led him to propose the theory of
symbiogenesis - that larger, more
complex cells evolved from the
symbiotic relationship between less complex ones. He presented this theory in 1909, in his Russian work,
The Theory of Two Plasms as the Basis of Symbiogenesis, a New Study or the Origins of Organisms, although the fundamentals of the idea already had appeared in his earlier
1905 work,
The nature and origins of chromatophores in the plant kingdom.
He was inspired by his work as a leading
lichenologist -
lichens were of major interest at the time as it had recently been shown that they exhibit a symbiotic relationship between
fungi and
algae. Around the turn of the century he
collected a sizeable lichen
herbarium, containing over 2000 specimens from lands in
Russia,
Austria and around the
Mediterranean. The collection is currently in the possession of
Kazan University. He also studied
hydras.
Merezhkovsky rejected
Darwinian evolutionary theory. He didn't believe that
natural selection could explain biological novelty, positing instead the acquisition and inheritance of
microbes as central. He was criticised by another Russian lichenologist,
Alexandr Alexandrovich Elenkin.
Although the
modern evolutionary synthesis supports Darwin's theory of evolution by natural selection, Merezhovsky's ideas of symbiogenesis are reflected in the modern
endosymbiotic theory developed and popularised by
Lynn Margulis. In this,
organelles such as
chloroplasts and
mitochondria are the descendants of
bacteria that evolved into an
intracellular symbiosis with early
eukaryotic cells.
