He could perform some DNA tests that could show how those species were related. For example, genome sequencing could show all the differences in DNA nucleotides. The number of changes could then be multiplied by the rate of mutations and the result would show how species were related.
Mercaptoethanol is the chemical compound with the formula HOCH2CH2SH. ME , as it is commonly abbreviated, is used to reduce disulfide bonds and can act as a biological antioxidant by scavenging hydroxyl radicals (amongst others).
