Answer:
.
Explanation:
To explain the last sentence, what I mean by that is the sudden decrease in air pollution in just a few weeks is what would have typically taken multiple years to do. Due to less drivers, factories shutting down, and more, less toxic and infirm mental hazardous chemicals were released into the atmosphere in an extremely short amount of time. However, nowdays, it is almost back to where is was before the pandemic.
Similarities: Natural Selection and Artificial Selection both result in the alteration of the gene pool. It can also change phenotypes of different species'.
Differences: Artificial Selection is when a specific trait is not wanted, and so it is not bred.
For example, humans did not like how yellow peas looked. They liked the healthy looking green better. So, they killed the yellow peas, and bred the green peas with other green pea plants, and right now it is almost completely out of our gene pool.
Natural Selection is when something naturally occurs, such as a natural disaster, famine, plague, invasive species introduction.
For example, if 10 camels lived in a desert, but one of them didn't have as good of a metabolism and stayed full longer, then that one would survive, while the others might not.
The duplication of homeotic ( H o x ) genes has been significant in the evolution of animals because it <u>permitted </u><u>the </u><u>evolution </u><u>of novel forms</u>
<h3>What is the Hox genes and evolution?</h3>
Hox proteins are a family of transcription factors that have undergone extensive conservation. They were first identified in Drosophila for their crucial functions in regulating segmental identity along the antero-posterior (AP) axis.
The regionalization of the AP axis and changes in the expression patterns of these genes have been strongly correlated during the past 30 years across a wide range of evolutionarily distinct species, indicating that Hox genes have been essential in the evolution of new body plans within Bilateria.
Despite this extensive functional conservation and the significance of these genes for AP patterning, many important concerns about Hox biology remain.

Answer:
Yes, man has been curious about the world and his existence since the beginning, Due to this curiosity, man has always tried to solve the mystery of life. With the passage of time, the observation and discoveries of man led him to reach to all the modern advances which can be seen today in the world. Today, man has a better knowledge about his existence and the existence of life on Earth. Although a lot has yet to be discovered but we have been able to solve a lot of the mystery of the earth.
