C.R. helped with experiments and analyses.
M.G., A.T., J.M.T., S.K., P.B. and J.J. supervised the experiments and analyses.
A.B. performed most experiments and analyses to which A.L. also contributed.
Investigators were blinded for treatment or genotype of mice or both in all experiments and analyses.
C.L., C.V., I.L., O.F., X.A., E.G., F.S. and R.L.S., performed aDNA experiments and analyses.
See our paper for the full set of experiments and analyses.
Safety was evaluated by both experiments and analyses.
R.B. conducted the climate model experiments and analyses, and wrote the main paper and the Supplementary Information.
P.A.N. planned and executed experiments and analyses, supervised data acquisition, performed bioinformatic analyses, and extracted nucleic acids for the MAGIC cohort.
L.L. conceived and developed the project and performed most wet-lab experiments and analyses, with help from S.E.B. A.L. performed transplantation experiments.
Follow-up experiments and analyses showed that the machine preference was stable and could not be attributed to participants' mood, to their perception of text-messaging difficulty, or to the novelty of a chatterbot.
