The correct answer is option b) "That our early ancestors were tailed primates".
Explanation:
Rarely, some newborn children developed an elongated coccyx, known as an elongated tailbone or a pseudotail. This is an example of vestigiality, which is the presence of ancient body structures that do not longer serve a purpose. In this case, vestigial tails indicate that our early ancestors were tailed primates. Other examples of human vestigiality include wisdom teeth, appendix, and body hair.
Tusks are essentially overgrown teeth. Yet they’re typically used for most task of daily living; digging for water or vital minerals in the ground, debating trees to secure fibrous food, and helping males compete for females
The relationship between sunlight and chlorophyll is that chlorophyll absorbs sunlight and uses its energy to synthesise carbohydrates from CO2 and water.
These are both needed in photosynthesis because without sunlight and the chlorophyll, photosynthesis would not be able to synthesise carbohydrates from CO2.
