Explanation / Answer

Species 1 is more closely related to 2 and 3 than 4 and 5 as it is more closer to 2 and 3 in the phylogenic tree.

Blue hair is a derived trait as it appears in the most recent ancestor of Family 1.

Wings are present in Species 4,5 and 6 and has undergone no change thus it is an ancestral trait for Genus B.

Species 1 has undergone no branching making it the most basal taxa.

Clearly from the tree species 6 is more close to 4 and 5 than to 2 and 3.

Yes 2 and 3 are sister taxa as they branch out from the same node.
