ScienceDaily (Oct. 9,
2012) — Just because a lizard can grow back its tail, doesn't mean it will
be exactly the same. A multidisciplinary team of scientists from Arizona State
University and the University of Arizona examined the anatomical and
microscopic make-up of regenerated lizard tails and discovered that the new
tails are quite different from the original ones.
The findings
are published in a pair of articles featured in a special October edition of
the journal, The Anatomical Record.
"The
regenerated lizard tail is not perfect replica," said Rebecca Fisher, an
associate professor in ASU's School of Life Sciences, and at the UA College of
Medicine -- Phoenix. "There are key anatomical differences including the
presence of a cartilaginous rod and elongated muscle fibers spanning the length
of the regenerated tail."
