Garstang's Auricularia hypothesis suggests that ancestral vertebrates may have evolved from urochordate larvae.
What is Garstang's Auricularia?
The auricularia hypothesis, proposed by Garstang was an attempt to explain how the chordate body plan originated from a deuterostome common ancestor by emphasizing the significance of changes in larval forms. According to the Garstang Hypothesis, development of sexual maturity in a non-metamorphosing lineage of tunicates might provide the immediate proto-chordate ancestors of more typical chordates.

Abiotic factors (such as weather and environment) will determine which organism will be superior compared to another.
For example, Lion will be placed as the highest in the food chain if they're in Savanna environment. But, if we place that lion in the middle of the ocean, the lion will not has the superiority that it has on land.</span><span />
