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.

Research on gender differences would lead one to anticipate that Alex is "less" likely to detect faint odors and "less" likely to smile frequently than his sister Shayna.
Men and females enormously vary in their perceptual assessment of odors, with ladies outflanking men on numerous sorts of smell tests. Women’s unrivaled olfactory capacity is a fundamental characteristic that has been acquired and afterward kept up all through evolution, a thought communicated by Romanian dramatist Eugene Ionesco when he said "a nose that can see is worth two that sniff."
Answer:
<em>Goods were produced efficiently and needed more efficient transportation.</em>
Explanation:
The transport evolved mainly during the Industrial Revolution because the industry began to produce much and with great efficiency, which generated the need for improvements in the automobiles of the time, so that the transportation of the goods produced did not damage the quality. Initially, most of these improvements were restricted to England and the 2nd Industrial Revolution (1850-1900), conquered other countries in Europe, America and Asia. Including maritime and land transport, with the creation of ships and locomotive.
