Hi, welcome and thanks for joining me today in a video about using biochemical signatures to determine evolutionary relationships.
00:07
And the pattern we see is the more similar the biochemical, the more similar or closer they are related evolutionarily.
00:14
So this would be using things like dna, rna, amino acids, and proteins as evidence.
00:19
And again, dna codes for rna, which codes for amino acids, which make up proteins.
00:24
So let's look at this example here because this works really good.
00:26
And a lot of times they'll use things like ribosomal rna or dna to do this.
00:31
So i have a dna example here.
00:33
So my example is for dna.
00:35
So let's say we have three different species.
00:39
One, two, and three up here on my phylogenetic tree or my cladogram...
