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.

Answer:
This is for the table at the top
<em>Plentiful roaming space</em>- increase - <u>because they</u><u> have more space they can live in.</u>
<em>Severe</em><em> </em><em>drought</em><em> </em><em>-</em><em> </em>decrease<em>-</em><em> </em><em> </em><u>because they</u><u> </u><u>wont</u><u> </u><u>have</u><u> </u><u>enough</u><u> </u><u>water</u><u> </u>

<em>Habitat </em><em>destruction</em><em> </em><em>-</em><em> </em>decrease - <u>Because they won't have a place to live in </u>
<em>Elimination of predators</em><em> </em><em>-</em><em> </em>increase - <u>Because there will be less animals hunting them for food.</u>
<em>Lack of competition</em><em> </em><em>-</em><em> </em>increase - <u>Because they won't have to compete for food which will allow them to have more.</u>
<em>Disease</em><em> </em><em>outbreak</em> - decrease - <u>Because the disease will kill a lot of them and can potentially cause birth rates to go down</u>
