Milk snakes are a species of nonpoisonous snakes that inhabit a wide geographical range throughout North America. They can be gr
ay, tan, red, orange, or black with or without bands of yellow, black, or white. Biologists have proposed that brightly colored milk snakes are adapted to regions where similarly colored poisonous snakes live because the color wards off potential predators. This is a(n) _______ explanation.
In biology, a proximate explanation refers to an event that is directly responsible for producing a specific result. A proximate explanation allows to explain a particular biological phenomenon immediately associated with physiological factors. In sociology, a proximate explanation enables understanding of human behavior by their more immediate factors. On the other hand, an ultimate explanation is believed to be the real cause of the observed results.
Vertebrate paleontology covers everything from the tiny, fish-like creatures, to the salamander-like ancestors of all land vertebrates, to dinosaurs, mammals, flying and swimming reptiles, etc.
Hypomorphic Alleles
: A change that reduces, however, doesn't dispense with a gene's usefulness is hypomorphic. A progressively extreme condition, amorphic transformation, dispenses with the gene's capacity.
The great analyses characterizing hypomorphic alleles go back to the 1930s. Herman Miller, who won a Nobel Prize for finding that radioactivity causes changes, considered the eyeshade of organic product flies. These flies typically have red eyes, yet freak assortments can have white or apricot-hued eyes. The allele liable for various natural product fly-eye hues is known as the white allele, with the contraction "w."
