Question

use the dropdown menus to complete the passage. prior to dna analysis, much of phylogeny was assumed based on physical characteristics. domesticated dogs share many of their physical characteristics with jackals, wolves, and wild dogs, and thus they were classified and named accordingly. recently, by comparing dna analysis for these species, researchers have been able to better understand dropdown menu. this has changed much of what was assumed and has led to dropdown menu. the options for the first dropdown are: how to recognize different species in the wild, how species are related to each other, how to prevent genetic mutations

Explanation:

Phylogeny is the study of the evolutionary history and relationships among species. DNA analysis helps in understanding these relationships. Recognizing species in the wild (first option) is more about physical traits or field - identification methods. Preventing genetic mutations (third option) is about genetic engineering or environmental protection against mutagens. But DNA analysis in phylogeny (as the passage starts with phylogeny) is mainly about understanding species' relatedness.

Answer:

how species are related to each other
