A scientist finds a new organism that may be either a bird or a bat, but it is not clear which group it belongs to. He is pretty sure that the organism has analogous structures with bats and homologous structures with birds, as suggested by genomic data. The organism has one trait that is shared with bats but not birds. Which group should he choose for the new organism and why? A) Bats because of the analogous structures; the trait shared only with bats is ancestral.

B) Birds because of the homologous structures; the trait shared only with bats is ancestral.

C) Birds because of the homologous structures; the trait shared only with bats is derived.
