Common vampire bats [Desmodus rotundus] feed only on blood and die after 70 h of fasting. Unfed bats often receive food from other bats by regurgitation. The graph shows the changes in weight at the time of feeding compared to the pre-feeding weight $(100 \%)$ of donor and recipient bats before and after blood donation.
Using the data, explain blood sharing in vampire bats is an example of the development of altruistic behaviour by natural selection.
