Definition: Compose a new way to ask the same question. The new question must be asking the exact same thing as the original question does. Without any other information, you should be able to tell that the original question and the new question are the same. Preserve bracketed phrases in your new question. You can change the rest of the question provided the above requirements are satisfied. The new question must have a natural, fluent formulation, as if it were composed by a native English speaker. You will be given three pieces of information to help you create better questions. Those are: "Answer": the answer to the question, e.g., "Honolulu". "Answer Type": the type of the answer, e.g., "Location". "Auxiliary Information" is a detailed description of some concepts mentioned in the question, if any.
Input: original question: Which fossil specimen has the organism of [Adapidae]?
answer: darwinius masillae
answer type: Fossil specimen.
auxiliary information: Adapidae is a family of extinct primates that primarily radiated during the Eocene epoch between about 55 and 34 million years ago. Adapid systematics and evolutionary relationships are controversial, but there is fairly good evidence from the postcranial skeleton that adapids were stem strepsirrhines. In particular, the anatomy of the adapid wrist and ankle show derived similarities with those of living strepsirrhines. However, adapids lacked many of the anatomical specializations characteristic of living strepsirrhines, such as a toothcomb, a toilet-claw on the second pedal digit, and a reduction in the size of the promontory branch of the internal carotid artery. There are two major branches of adapids, subfamily Adapinae and subfamily Caenopithecinae. Caenopithecines are sometimes assigned to their own family, Caenopithecidae.
