The Skeletal System
The skeletal system of any organism is a vital part of their existence. As species evolve and change, adapting to their changing environments and responding to outside stimuli, scientists have discovered hat the presence of a suitable skeleton in the animal is a necessity for their survival. As you look though the list of phyla and species shown here on this webpage, you can see that many of the skeletal systems and even the internal body structures of species from different phyla are very similar. This is due to the similar environments the species evolved in, the common ancestors they share and finally the possibility of genetic similarities between species due to inter-breeding
As the Biology students of Xavier High School have learned throughout their studies of evolution, Binomial Nomenclature, and the taxonomy system, species that may seem to be distantly related can often share many surprising similarities. We can see this in the skeletons most noticeably. Several species on our list have developed a form of skeleton known as a hydro-static skeleton. This amazing feat of evolution formed due to the inability of these organisms, such as the Divided Flatworm, to develop a solid bone structure. Skeletons can exist in a variety of forms, and this form is what best suits its needs. So it is not surprising that one would find a different species classified in a different phylum that evolved in a similar environment to develop a similar skeletal system. In fact, one might find if you look deeper a common ancestry.
As many bio students have learned, sometimes that taxonomy system doesn’t work in certain areas. This is where many scientists move to cladograms. As scientist have discovered, these cladograms display new insights into the ancestry and evolution of a species that we have not seen before. In fact, many of the species listed here share a single common ancestor, and many more recent common ancestors. This is another reason why we see similarities in these organisms and also notice stark differences.
In conclusion, the skeletal system of any organism is a vital part of their existence. This website explains the skeletal systems of three species for each of the nine different phylums of the Anemilia kingdom. We hope all the information on this webpage can teach you about each species' skeletal system, and answer all the questions you might have.
