The unmatched sequencing efforts have as of October 2020, produced almost nearly 200,000 genomes of acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causing havoc in the world, named as Covid-19.
Understanding the drift in the evolution of SARS-CoV-2 is equally supreme in controlling this global pandemic. The major challenge lies in the investigation of an extensive dataset. It shows that the drastic evolution of this SARS-CoV-2 throughout the global pandemic is mainly detected majorly by purifying selection but a small set of plots. In addition, the spike 614 and nucleocapsid 203-204 which materialize to evolve under the positive selection are a must for consideration.
This replacement in the spike protein, multiple substitutions in the nucleocapsid is vital for SARS-CoV-2 adaptation to the human host. The positively selected mutations form an effectively connected matrix of evident epistatic interactions which are signatures of primary partitions in the SARS-CoV-2 phylogeny. These separations show sharp spatial and temporal dynamics, with both the globalization and diversification current being obvious.
