"Chief Medical Officer's log. This will be my final report to the Enterprise. Just as changes in evolution are known to be caused by changes in the environment we now know the process also works in reverse. An attempt to control Human evolution has resulted in a new species that's lethal to its predecessors. The children will be condemned to live out their lives in isolation. The quarantine of the Darwin Station must be maintained forever."
"Chief Medical Officer's log, supplemental. The adults of Darwin Station have been restored to normal health using our transporter. They will remain on Gagarin IV and continue their research in hopes of one day rejoining their children."
"Scientists believe no experiment is a failure that even a mistake advances the evolution of understanding. But all achievement has a price. For one brief glimpse at the mysterious blueprint of Human evolution the men and women of the USS Lantree paid with their lives. Their sacrifice is thus noted in this scientist's log."
