Why would gene duplication events, such as those seen in the Hox gene complex, set the stage for adaptive radiation?
A) There are more copies of genes, meaning speciation had occurred by polyploidy.
B) The original gene copy is the outgroup, and the new gene copies are the adaptive radiation.
C) Without duplicated genes, species would be vulnerable to extinction.
D) One copy of a gene can perform the original function, while other copies are available to take on new functions.

Gene duplication events create extra copies of genes, which allows for redundancy in function, and provides an opportunity for the copies to evolve new functions. This can lead to the development of new traits and adaptations, ultimately setting the stage for adaptive radiation.
