The statement best supported by the theory of evolution is:
An individual’s characteristics allow it to survive and reproduce more successfully in a particular environment than a member of the species with less desirable characteristics.
This statement aligns with the principles of natural selection, which suggest that organisms with traits better suited to their environment are more likely to survive and reproduce. These advantageous traits can then be passed on to future generations. The other options are more absolute and do not account for variations in environments or other factors influencing survival and reproduction.
