Biology Genetics or Evolution in Essay

For many years, scientists have considered whether when different species evolve to look the same if they do indeed share a common genetic mechanism. The researchers have found it interesting because it tells about how flexible evolution is. If the same wing pattern evolves independently in different populations then it is expected that the same genes are not involved.

Due to the fact that butterflies have thousands of genes in their genome, most scientists felt it was unlikely that the same genes would be involved, but the results of this study have shown that they are in fact the same. This proves that one of these butterflies has evolved itself over the years to look exactly like the other so that their chances of being attacked by birds would decrease.References
