Third, the jaw musculature seems to be homologous to the original gill support musculature. Geologic Time Scale 3. Thus, the vertebrate jaw appears to be homologous to the gill arches of jawless fishes. Nauplius larvae of A a barnacle Tetraclita, seen in ventral view and B a shrimp Penaeus, seen in dorsal view. The shrimp and barnacle share a similar larval stage despite their radical divergence in later development.

Thus, the middle ear bones of the mammal are homologous to the posterior lower jaw of the reptile and to the gill arches of agnathan fishes.
Thus, the vertebrate jaw appears to be homologous to the gill arches of jawless fishes. Biochemistry—Molecular Clock He pointed out the existence of eyes in embryonic moles, pelvic rudiments in embryonic snakes, and teeth in embryonic baleen whales. Embryonic homologies One of the most important distinctions made by the evolutionary embryologists was the difference between analogy and homology. Lumen Learning Follow.

Sunderland MA : Sinauer Associates; For instance, the bird wing and the bat wing are homologous as forelimbs, but not as wings. The upper portion of the second embryonic arch supporting the gill became the hyomandibular bone of jawed fishes.

Evidence for Evolution Graduate Seminar The three main claims of Darwinian evolution Molecular phylogeny of Hawaiian and other Campanulaceae.
Charles Darwin's theory of evolution restructured comparative embryology and gave it a new There is ample evidence that jaws are modified gill supports.
One of the most important distinctions made by the evolutionary embryologists was the difference between analogy and homology. Are you sure you want to Yes No. When the gill slits became supported by cartilaginous elements, the first set of these gill supports surrounded the mouth to form the jaw.
Evidence of evolution.
The quadrate bone of the reptilian upper jaw evolved into the mammalian incus bone of the middle ear, and the articular bone of the reptile's lower jaw has become our malleus.
