1. Of or relating to bradytely.
   • 1944, George G. Simpson, Tempo and mode in evolution, Columbia University Press, page 133:

     A distinction is to be made between slow horotelic rates and bradytelic rates, also slow but essentially a different phenomenon, as demonstrated by the marked difference in survivorship pattern, from which the existence of bradytelic rates have been deduced.

   • 1953, George G. Simpson, The Major Features of Evolution, Columbia University Press, pages 313–337:

     This low-rate, nonnhorotelic excess is bradytely and the rates involved in it are bradytelic.

   • 1978, Vishwambhar Puri, The so-called primitive angiosperms:

     Bradytelic — when organisms evolve at exceptionally slow rate. It is believed that this classification applies to plants also. Many annual species like Gilia, Clarkia, and many epiphytic orchids are tachytelic while Magnolia, Cer- cidiphyllum, ...

   • 1979, Carnegie Museum of Natural History, Bulletin of Carnegie Museum of Natural History:

     For example, bradytelic lines — defined by Simpson (1953:113) as "low rates" or "arrested evolution" — imply, above all, extremely low rates of morphological evolution over a considerable span of time — usually at least 100 million years.

   • 2001, J. William Schopf, Cradle of Life: The Discovery of Earth's Earliest Fossils, Princeton University Press, →ISBN, page 212:

     Slow bradytelic evolvers are famous as living fossils. Good examples are horseshoe crabs, coelacanth fish, crocodiles, opossums, and primitive lampshells (linguloid brachiopods). Simpson pegged these as bradytelic because they belong to ...
