Question: When endothermy first appeared in the evolution of mammals is uncertain. Modern monotremes have lower body temperatures and more variable metabolic rates than marsupials and placentals, but there is evidence that some of their ancestors, perhaps including ancestors of the therians, may have had body temperatures like those of modern therians. Some of the evidence found so far suggests that Triassic cynodonts had fairly high metabolic rates, but it is not conclusive. For small animals, an insulative covering like fur is necessary for the maintenance of a high and stable body temperature.
Is there an answer to this question: What does evidence found suggest about monotremes?

Answer: unanswerable


Question: The discovery of gold in Victoria in mid 1851 led to the Victorian gold rush, and Melbourne, which served as the major port and provided most services for the region, experienced rapid growth. Within months, the city's population had increased by nearly three-quarters, from 25,000 to 40,000 inhabitants.

Additionally, Melbourne along with the Victorian regional cities of Ballarat and Geelong became the wealthiest cities in the world during the Gold Rush era.

Answer: three-quarters, from 25,000 to 40,000 inhabitants
