Which of the following is an example of deep homology? The eyes of humans and fruitflies are morphologically very different, however they use the same proteins to transduce light into a nerve signal. There is very little genetic diversity across the human population near our lactase gene. Many proteins found in venoms are also expressed in other tissues. Two different members of the same gene family have gained the ability to digest cellulose in different vertebrates

Step 1: Deep homology refers to the similarity of developmental mechanisms or genetic pathways between distantly related organisms, even if the resulting structures look very different. Show more…

Which observations are examples of homologies? The skin flaps for gliding that evolved separately in sugar gliders and flying squirrels help them use similar habitat niches. The Pax6 gene in vertebrates and the eyeless gene in flies have similar sequences, and both regulate embryonic eye development. The bones that support the wings of birds, pterosaurs, and bats are arranged in the same order in each animal. The ability to fly using elongated wings developed independently in the lineages that led to birds, pterosaurs, and bats. The pharyngeal arches found in all vertebrate embryos develop into gill supports in fish and throat structures in mammals.
