Of fish and men: clonal lineage analysis identifies divergence in myocardial development

Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

Speciation is the evolutionary process resulting in the formation of new, distinct species—groups of reproductively isolated populations.
