Explanation / Answer

Phylogenetics:

This is the study of evolutionary relationships between the organisms that is closely related sharing a common ancestor or distantly related, to understand the evolutionary divergence of the organism.

Question:

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:

Rank 1: Flea

Flea is closely related to horseflies because the phylogenetic tree shows common branch with horseflies. They would have evolved from a common ancestor.

Rank 2: human body louse and katydid

Human body louse and katydid is equally closely related to horseflies. Their relatedness is shown by connecting the branches between them.

Rank 3: dragon fly and mayfly

Rank 4: Silverfish

Silverfish is distantly related to horseflies.
