scientist have been able to infer the relationships between the major groups of vertebrates by bones
i dont know stupid
Scientists classify vertebrate into different groups by the way the animal looks or how big or small it is
The presece of a vertebrate.
The vertebrates are animals with a backbone. Scientists separate this group into smaller groups because of their features:how the animal takes in oxygen -- lungs, gills or through the skinthermoregulation -- maintains own temperature (homeotherms) or temperature varies with surroundings (poikilotherms)reproduction -- internal or external fertilization, lay eggs (oviparous) or give birth to live young (viviparous).
vertbrates are classified into different groups cause they have backbone and spine of structures for each group

The five groups are Fish, Amphibians, Reptiles, Birds, Mammals

The vertebrates are further divided into five groups or classes.
There are five groups of vertebrates; fish, amphibians, reptiles, birds and mammals.
The relationship between the two is that they bother separate things into groups or sections.
