4.2. Why gene/protein sequences may be similar?

Before measuring the similaritybetween the sequences, it's interesting to answer the question: why gene or protein sequences may be similar? It is indeed veryinteresting because the answer is related to the theory ofevolution which is due, as you all know, to Darwin. What Darwinsays is that species evolve in time and there is a creation ofnew species for existing ones. So there is an evolutionof species over time. He was a very thinking man, huh. This evolution can be also seenon the genomic sequences. Let's see this very small and partialtree of life and hypothetical tree of life. Here you have thespecies and you have this phenomenon of speciation giving ...
