Mosses and worts are non-vascular. The ferns were the first plant species to develop a circulatory system that lets them grow larger. They have roots, leaves, stems, and trunks. With their new vascular system, the sky was the limit for plants.

What would have happened if humans had not developed a circulatory system?
Humans didn't develop a circulatory system. Early forms of circulatory systems developed in the first animals and organisms to roam the earth. As these species evolved through speciation and genetic variation, new species came to exist that also had circulatory systems. Over time, the systems became more complex and efficient (compare the cardiopulmonary circulatory system of the human compared to the circulation of a fish). Therefore, without circulatory systems there would be no humans nor would there be life as we know it
