Answer:
Flea is most closely related to horsefly, whereas silverfish is most distantly related to horsefly
Explanation:
The question image is given below. Here is the complete question with the transcribed Image Text;
This is one possible phylogenetic tree representing the relationships between some members of phylum Arthropoda. Use this phylogenetic tree and your knowledge of cladistics to determine the relationships between these species. Rank the species from most closely related to horseflies to most distantly related to horseflies. If two species are equally close in their relatedness to horseflies, overlap them.
Answer:
↓↓↓ Most closely related species to the horsefly ↓↓↓
FLEA
KATYDID / HUMAN LOUSE
MAYFLY / DRAGONFLY
SILVERFISH
↑↑↑ Most distantly related species to the horsefly ↑↑↑
Note: A slash "/" is used to overlap species
Evolutionary relationships between organisms are shown by phylogenetic trees. The organisms that are most closely related have more common ancestor than the most distantly related species. Hence, in the picture of phylogenetic tree below, fleas are more closely related to horseflies, even though some other species look like horseflies than fleas do.
