Phylogenetic analysis is the study of the evolutionary development of a species or a group of organisms or a particular characteristic of an organism, like a gene or protein. Several approaches are used in such analysis, like multiple alignment and phylogenetic tree reconstruction.
A phylogenetic tree is a graphical representation of evolutionary origin of different species, organisms, or genes from a common ancestor.
Let's climb this tree.
Our genome contains only a few percent of protein-coding sequences; the vast majority of it is occupied by non-coding and regulatory sequences. And their phylogenetic analysis is a non-trivial and very complex task.
But let's try to understand the evolution of such sequences and build a phylogenetic tree for them too.
Find what's hidden in the tree crowns.
The year of 2019 gave us the perfect object to study in the light of evolution. The SARS-CoV-2 coronavirus outbreak, first reported in Wuhan province in China in December 2019, has resulted in a pandemic affecting 213 countries and territories worldwide.
The virus spreads very quickly and, walking through the human population, constantly changes, giving rise to new strains, sometimes with new properties and requiring a different approach to treatment.
Let's hunt down the new strains.
