We're continuing our test of Lamarck's hypothesis that physiological adaptation creates heritable changes in species. This test takes at least a few weaks.

Protocol
1. Start the crosses (   • Class 8 Assignment (Lamarck)  )
2. After roughly a week (or when you see pupa on the sides of your vials), remove the parents from your crosses.
3. When the next generation of adult flies start to emerge (at least 10 days after you started your crosses), transfer the flies to an empty vial labeled with the cross (for example, "cold Ebony female x warm Ebony male").
4. Place the vial with the transferred flies in the fridge to anaesthetize them, checking every five minutes or so to see how long they resist falling asleep in the cold.
5. Once your new flies are anaesthetized, sort them into males and females, and populate your spreadsheet with their phenotypes (for example, "White eyes female x White eyes male children: females 1-5 have white eyes"). *Note that many of your crosses won't show any unusual phenotypes. Either way, mark the total number of flies from that cross each day, as well as the time it takes to anaesthetize that cross's flies each day.
