From the article:
SHANGHAI, China (AP) -- Doctors in Shanghai on Tuesday were considering
surgery options for a 2-month-old boy born with an unusually well-formed
third arm.
Neither of the boy's two left arms is fully functional and tests have so
far been unable to determine which was more developed, said Dr. Chen
Bochang, head of the orthopedics department at Shanghai Children's
Medical Center.
"His case is quite peculiar. We have no record of any child with such a
complete third arm," Chen said in a telephone interview.

With some inbreeding, perhaps a race of three-armed humans will develop.

Isn't the boy most likely a chimera, with the extra arm coming from his
twin?
Would a genetic test show different DNA from each arm if
this were the case?
By definition, a chimera would show different DNA from different
parts. However it could be an example of a conjoined twin which would
be an identical twin with the same DNA. Or else it could be a
developmental anomaly with a duplication in the expression for the
arm. Technically, an identical twin or a conjoined twin is exactly
the same kind of developmental anomaly, the difference being merely in
how early the anomaly occurs and how complete an organism is
duplicated.
