Descriptions of both insect/bird
Both Miami blue butterflies and scrub jays have differ in this The scrub jays The “blue jay” of dry lowlands along the Pacific seaboard, the California Scrub-Jay combines deep azure blue, clean white underparts, and soft gray-brown. It looks very similar to the Woodhouse's Scrub-Jay (they were considered the same species until 2016), but is brighter and more contrasting, with a bold blue breast band.
Maimi Butterfly
Adults:The adults are small with a wingspan range of 22 to 31 mm. Females are generally larger than males. The sexes are dimorphic. The upper surface of the wings is bright blue in males. Females have reduced blue with wide gray wing borders and an orange-capped black spot along the outer margin of the hindwing. The undersides of the wings are gray in both sexes. The hindwing has a broad white submarginal band and four black postbasal spots.
Theory of natural selection by Charles Darwin explains the moth appearance in England. The theory of genetics describes this as a mere shift of trait due to environmental factors.
<h3><u>Explanation:</u></h3>
Peppered moths are the moths found in England from a long time ago. The environment before the industrial revolution was pure and pollution free, which led to the growth of the white variety of moths as they were able to camouflage better with the bark of the trees from their hunters. The white trait were the parents, and fertilization between the two recessive traits gave rise to the recessive traits only.
But with the industrial revolution, the pollution increased to a huge extent, leading to deposition of smokes and soot on trees bark where white variety of the white moths got easily recognizable. This led to the black moths which now can camouflage better. Thus the nature selected black variety over white variety for better survival, and the white variety reduced dramatically.
