To determine which species is most closely related to species 4, we need to analyze the phylogenetic tree you mentioned. Since I cannot see the phylogeny depicted above, I can provide general guidance on how to interpret it.

In a phylogenetic tree:

  • Species that share a more recent common ancestor are considered more closely related.
  • If species 4 shares a branch point with species 1 or species 3, then it will be more closely related to one of those.
  • If it does not share a branch point with either, it may be equally related to both or more distantly related.

Without seeing the tree, the best conclusion I can provide is, if the tree shows species 4 branching from the same point as either species 1 or species 3, it would be most closely related to that species.

Thus, based on your options, if species 4 is closer to species 1 or 3 in that phylogeny, the answer would be:

  • If species 4 is directly connected to species 1, then it is more closely related to species 1.
  • If it is directly connected to species 3, then it is more closely related to species 3.
  • If both species 1 and 3 are equidistant from species 4, then option "1 or 3 (Can't tell)" would be appropriate.

Please refer to the actual tree to determine the correct answer.
