Which character of vertebrates is associated with colonization of land?
Answers
Hemoglobin, powerful respiratory system and locomotion and an evolved nervous system gave vertebrates the ability to colonize land.
Explanation:
Before the vertebrates insects had colonized land.They could breathe on land and they some ancient insects reached large sizes too. However they did not possess lungs a four chambered heart or hemoglobin.
These three made it possible for vertebrates to use the oxygen in the atmosphere and reach it to all the cells specially the muscle cells.
Vertebrates acquired a good thermoregulatory system too,as a consequence of the above.
They also had a more evolved nervous system in which brain and sense organs worked in coordination with the muscular system.
Vertebrates got better at figuring out distance and depth.This helped them to catch prey or evade predators.
