the rare genotype Reseune finds of commercial or experimental interest. This is such a case, a fetus near term. In fact, Reseune has absorbed all cost on this replication, whose designation is ŁIT-*-**-***-****PR: the parent-subject is uniquely talented, willing to trade genetic uniqueness for one replicate, and willing to sign a release opening all informational records of applicable interest to Reseune: Reseune will store that data for future development of the geneset, but will not release the geneset for commercial use until fifty years after the decease of parent and replicate.
Reseune puts ten geneset s in storage as A**-l.
3ATCH AGCULT-789X: ONE UNIT:
A day along, in a womb-tank in a large building somewhat downhill from the last facility, is AGCULT-789X. AGCULT-789X, experimental as the X-designation indicates, closely resembles the RYX-20s or the EL’-4651s, except that the genetic codes of the RYX-20s and the EU-4651s indicate two feet while that of AGCULT-789X indicates four, and the RYX-20’s and the EU-4651’s codes indicate smooth skin, while AGCULT-789X’s indicates a sleek bay hide and a superlative ability to run.
AGCULT-789X is exceedingly rare material, Terran in origin, another attempt at a species with which Cyteen has had limited success. The AGCULT programs, involving not only animal species, but also botanical studies, have had far more success with the algae and with the lower end of a food-chain which may one day support the descendants of Terran species. In a much-heralded gesture toward peace, Earth has provided Cyteen with genesets and data on the whole range of Terran species, with particular emphasis on the endangered or extinct, along with human genesets which may contain genetic information missing from Union and Alliance genepools.
Reciprocally, Union has released representative genesets of Union populations to Terran genetic archives, in an exchange program designed to provide a valuable comparison between the two populations, and to provide a reference in event of global catastrophe or unforeseen lapse in contact.
Of the two worlds presently supporting human colonies, one, Downbelow, is, of course, a protectorate, and there is no question of changing the environment to any extent that would wipe out the indigenes. Humanity remains a visitor to Downbelow.
Cyteen, far less hospitable, harboring no species more advanced than the various platytheres and ankyloderms, was far more suitable for radical terraforming, and Cyteen’s ability to store genetic material against irrevocable climatic and atmospheric change at least raises hopes of selective recoveries in specific protected habitats should changes exceed their intended limits.
Terraforming, while wreaking havoc on many native species, has provided a unique opportunity to study interface zones and compare adaptive changes in Terrene and indigenous species, advancing our understanding of catastrophic changes which have impacted Terrene species over geologic time, and of the degree of change facing the human species in its radical changes of habitat.
Understanding that genetic changes are inevitable but not always desirable, Earth has begun to look on Cyteen as a repository for genetic information on species threatened with extinction. Some of the more ambitious projects involve large-mammal habitat, from the bottom of the food-chain up. Ironically, the experience in terraforming Cyteen, destructive as it has been of Cyteen’s indigenous life, is making possible the recovery of certain threatened ecosystems on Earth, and the establishment of more fragile systems on Mars, fourth planet of Sol system.
Certain of the proposed future exchanges are quite ambitious.
Earth is particularly anxious for the success of cetaceans and higher primates on Cyteen. It has proposed a joint study program as soon as the cetacean project is viable, for the study of cetacean development and the comparison of whalesong on Cyteen and on
