Those are DNA sequences. Each sequence of three bases in a DNA strand is called a codon. Each codon codes for a particular amino acid. So for example the codon AGC stands for the amino acids serine. The codon TGG stands for the amino acids threonine. The codon CTG stands for aspartic acid. So, the DNA sequence AGCTGGCTG codes for the amino acid sequence serine-threonine-aspartic acid. I hope the helps! :)

Allopatric speciation, also referred to as geographic speciation, is a method of the formation of new species due to isolation of the species from one another through geographic means.
The first step in this process is geographic isolation, which means that the original population is divided into two groups due to geographical reasons such as movement of continents or formation of water bodies.
Next, the species are subjected to different selection pressures due to their different environments. Eventually, the gene pool becomes very different for the two species due to the different selection pressures and because they are not allowed to mix.
Finally, after enough time passes, speciation occurs, which means that the two populations cannot breed to form fertile offspring.
