If we study all members of phylum Chordata then we will find great variation in their characters and due to this great variation, it is not so easy to divide them into different groups accurately. But the great effort of different taxonomists enables us to study them in different groups and different taxonomists present different … Read more
Now we are going to discuss a very interesting topic on Chordata, origin, and Ancestry of Chordata and we will try to understand how Chordata first arrived on our earth. In evolutionary trends, we know that simpler organisms give rise to more advanced forms, and in the case of Chordata most of the evidence points … Read more
In this article, we are going to discuss the vital difference between Chordata and non-chordates and we have already discussed definitions and examples of phylum Chordata, diversity in phylum Chordata, fundamental characteristics of phylum Chordata, and similar of phylum Chordata with higher non-chordate. Chordata and Nonchordate: In the animal kingdom we place all invertebrates in … Read more
We have already discussed 3 fundamental characters of the phylum Chordata which separate them from other Nonchordate animals and now we are going to discuss all the general characteristics features of phylum Chordata.
