What evolutionary development do scientists think occurred in the Cambrian period that gave rise to more complex fish?
They theorize that during this period the first of three gill arches on a jawless fish evolved into the first jaws.
Discuss the evolutionary significance of the development of the jaw?
Until now, it was unclear as to which genes control differences between the upper and lower jaw of the vertebrate head. Jawed vertebrates evolved from jawless ancest ors over 400 million years ago, and the evolution of a biting lower jaw was a critical step in vertebrate evolution. Comparative studies of vertebrate embryos suggest that lower jaws arose during evolution through changes in patterning along the proximodistal (PD) axis of the jaw as it forms.The jaw is one of a series of segmental reiterated structures called pharyngeal arches, and its PD axis, like appendages such as limbs, extends from the base of the arch to its tip. How this axis is established is still debated, but like limbs it clearly involves Dlx homeobox transcription factors related to distalless, a key regulator of appendage development in Drosophila.
How many pair of pharyngeal arches persists in human embryo?
4 extremely visible
What bone contains styloid process?
The styloid process is a bony protuberance off of the temporal bone. During embryological development, the dorsal end of the second pharyngeal arch cartilage forms the stapes and the styloid process. It is the cartilaginous viscerocranium that is derived from the first two pharyngeal arches.
What is the collective noun for arches?
Some arches/a few arches
Does Stan walker have a cleft palate?
Yes, his pharyngeal arches did not fuse at the right time (ie. at the 12th week of his embryonic life) His cleft palate resembles a primary condition (involving one side of his palate) which only occurs in 1 in 2500 live births in Australia.
