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:
This means that marriage and reproduction take place within the group, leading to decreased genetic diversity due to a lack of admixture.
Explanation:
<span>I think the right answer is "The traits that the minority group develops in trying to adapt". Allport investigated in depth about prejudice and discrimination in society. Based on these studies, I developed the Allport Prejudice Scale, which analyzes prejudice in 5 different scales; <span>antilocution, avoidance, discrimination, physical attack, and extermination.
