<Juliana G. Roscito> is a <biologist> whose research connects <embryonic development>, <evolution> and <genomics>. She earned her doctorate in developmental and evolutionary biology at the University of São Paulo in 2010 and subsequently conducted evolutionary-genomics research in Dresden. Her later work includes scientific management.<Juliana G. Roscito profile in NIMSB Support Units>[Juliana G. Roscito subsection: education, research and management chronology]{ref}
In <Digit evolution in gymnophthalmid lizards by Juliana G. Roscito and others>, she and collaborators compared the skeletal patterns of <tetrapod limbs> across <Gymnophthalmidae>. They distinguished mild reductions, such as loss of a few bones within <limb digits>, from more extreme reductions that leave no externally distinct adult limb. The study also examined <Sonic hedgehog> <gene expression> in strongly reduced developing limbs.<Digit evolution in gymnophthalmid lizards by Juliana G. Roscito and others>[Abstract: two groups of reduction patterns and Shh expression in forelimbs/hindlimbs]{ref}
The comparison joins an adult <phenotype> to an embryonic process. Two animals with superficially similar limb reduction need not have changed the same developmental step. Examining which skeletal elements remain, alongside spatial <gene expression>, makes that question more precise than simply counting visible toes. Those observations identify patterns to explain; they do not by themselves prove that every case of limb loss has one molecular cause.
