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
Which structures are present in a human embryo that are also present in the embryos of other species?
In a human embryo, structures such as pharyngeal arches, a tail, and a yolk sac are present, which are also found in the embryos of other vertebrate species. These features reflect shared evolutionary ancestry and developmental processes. For example, pharyngeal arches can develop into structures like gills in fish and parts of the jaw and ear in mammals. The presence of these common embryonic structures highlights the similarities across different species during early development.
Do you inhale or exhale when the diaphragm expands and arches upward?
When the diaphragm expands and arches upward, it creates more space in the chest cavity, allowing air to rush in. This is called the inhalation phase of breathing, so you would be inhaling during this process.

What is the collective noun for arches?
Some arches/a few arches
What is the derivation of the epiglottis?
The epiglottis is derived from the third and fourth pharyngeal arches during embryonic development. It forms from a combination of endodermal tissue and mesenchyme. The epiglottis plays a crucial role in covering the larynx during swallowing to prevent food and liquids from entering the airway.
