Chapter 27.1, Problem 1CC
Summary Introduction
To review:
The various features of vertebrates which are not present in invertebrate animals.
Introduction:
On the basis of the spinal cord, animals are classified into two parts: (1) Vertebrates and (2) Invertebrates.
Vertebrates and invertebrates originated from common ancestors. Vertebrates and invertebrate animals are necessary for nature.
Animals that have backbone are known as ‘vertebrates’. Vertebrates are the supreme species in the ‘Animal Kingdom’ with the backbone.
Invertebrates are identified as boneless animals. Molecular biology studies imply that all the invertebrates developed from a single invertebrate group.
