There are many experts and scientists that believe in evolution and feel that it can explain the changes that we have seen in organisms as time passes. One of the trends that has been seen to take place in evolution is cephalization. This is a trend that is used to describe how the head is shaped and how the brain has developed over time in different types of organisms. This means that since not all organisms have the same head shape or the same arrangement of neurons within the brain that there must be some type of trend that can be used to explain how the head shape has developed over time. In order to have a better understanding of cephalization, you need to know what the pros and cons really are of this evolutionary trend. Here are some of the pros and cons of Cephalization.
Pros of Cephalization
Offers and Explanation
The one thing that experts in Zoology are constantly searching for is an explanation. This means that they are looking for a way to determine how organisms have evolved over time and why the changes that have taken place exist. This is a trend that looks to explain why head shapes have become different. It offers some type of theory why this trend has taken place and why it is required in a evolutionary way. This means that people that are for this theory think that it offers a good explanation for why this trend has taken place over time.
Can be Substantiated
This is also a good theory because it is linked to other evolutionary trends that are in existence and can be substantiated by these. This gives it more credibility and allows cephalization to be taken seriously within the field of Zoology and science. This is not something that has been proven to be fact as of yet, but there is a lot of evidence that shows it is a theory that can be taken seriously, which is a major pro.
Cons of Cephalization
Not Believed By All
There are some within the field of zoology that do not agree with this theory and do not think that it can be used to describe the different head shapes that we find in different organisms. This means that since it is not widely accepted by all, it is not a theory that is proven fact and it is not a trend that is known to have occurred.
