in the course of fish evolution, two of the gill slits slowly advanced into the jaws.
The evolution of fish started about 530 million years in the past at some point during the Cambrian explosion. It become during this time that the early chordates advanced the cranium and the vertebral column, main to the first craniates and vertebrates. the first fish lineages belong to the Agnatha or jawless fish.
The earliest fish, corresponding to living hagfish, developed about 550 million years in the past. Diversifications that in the end advanced in fish include an entire vertebral column, jaws, and an endoskeleton manufactured from bones in preference to cartilage. Fish live in the course of the sea and in freshwater lakes and streams.
New studies have uncovered the genetic foundation of gill covers in fish, which came about over 430 million years ago. It sheds light on one of the most essential evolutionary traits for fish, in addition to over vertebrates.
In jawless fishes, a sequence of gills opened behind the mouth, and those gills became supported by way of cartilaginous elements. the primary set of these elements surrounded the mouth to shape the jaw.

Answer:
Because a lot of things have not yet been discovered and questioned as well as there being billions of things that we have absolutely no knowledge about.
The answer for your question is house holds

These principles MOST LIKELY represent
c. the main ideas of the State Constitution
Explanation:
The ideas of wisdom justice and moderation are a part of democracy for since its inception so it is to be understood in terms of the overarching ideals of the form of constitution of the state.
It is less likely to represent the different form of governance as the ideals such as these are to be found in all forms of government. The legislature must be full of wisdom and justice to be moderating.
Thus these are core values that represent the constitution and its aim as a body of laws and directions.
