Question

According to this figure, if a species were found only in Laurasia 135 million years ago, on which modern continents would its descendants most likely be found today?

A. Europe and Asia only
B. North America only
C. Africa and South America
D. North America, Europe, and Asia

Answer 1

The correct answer is option d. If a species were found only in Laurasia 135 million years ago, its descendants would most likely be found on the modern continents of North America, Europe, and Asia.

Step-by-step explanation:

Based on the information provided, if a species were found only in Laurasia 135 million years ago, its descendants would most likely be found on the modern continents of North America, Europe, and Asia (Option D). This is because Laurasia eventually broke up into these three continents.

The presence of unique flora and fauna in these regions, such as marsupial mammals in Australia and part of North America, supports the idea that different continents developed their own distinct ecosystems after the breakup of supercontinents like Pangaea and Gondwana.
