The correct answer should be D. ecological footprint
Biodiversity means having various species living together while habitat is a place of residence of species. Sustainability refers to the question whether or not something is ecologically sustainable.
Some examples of physical evidence that supports scientific theories that earth has evolved over geologic time are the studies have have been done supporting the idea of Pangaea that all the continents were together and with time separated, if you look at a map you can see that the continents almost fits like a puzzle, of course they do not because of erosion and climate change, but it’s the closest example.
Based on the description above, the molecular clock data
shows is that the Clams and Snails are more similar and related in structure
compared of the clams and squids. It is because it could be seen in the process
that organism are better in adapting to their environment in means of
increasing their number, survive and to pass on their traits to the next
generation.
