Vertebrates
are known to be animals with backbones.
The following are the evolutionary changes of vertebrates:
*Jaws
- Fishes before sucked and rubbed on their preys but now, they already have
jaws that enable them to more efficacious in getting their preys.
*Lungs
and limbs - Animals on the sea need to adapt when they look for their preys on
land, in turn, they had evolved to acquiring lungs for breathing and limbs for moving.
*Endothermy
- ‘Endo’ meaning internal and ‘therm’ meaning temperature. This gave animals’
bodies heat supply from burning the food they eat.
