Due to their pronounced intraspecific variability and to
difficulties in defining their evolutionary trends in mammalian
phylogenies, peripheral blood vessels have been neglected in
comparative studies. Supported by the Sonderforschungsbereich 89
(Car- diology) of the Deutsche Forschungsgemeinschaft, we have
reconstructed the ontoge- of the blood vessels of the tree shrew,
Tupaia belangeri, on the netic morphogenesis basis of a series of
developmental stages. The arteries of the lower extremity are
described and discussed here. Besides describing the morphogenesis
of the arteries in Tupaia, it is the aim of this study to explain
the variability of the arteries of the pelvic extremity among
mammals, and especially among primates including man, on the basis
of a common developmen- tal pattern. This can be shown in the
following example. In the popliteal region of most adult mammals
the arteria poplitea profunda is situated under the musculus
popliteus. In the adult Tupaia, as well as in primates, this artery
is missing but, superficial to the musculus popliteus, an arteria
poplitea super- ficialis exists. It seems difficult to explain such
a case of "discontinuous evolution," because it is hard to imagine
the position of the artery should have shifted through the muscle.
The present investigation and the literature show that early in the
embryonic development of a primate, man, and of Tupaia, both the
arteria poplitea profunda and the arteria poplitea superficialis
are present.
