Question

Describe 2 methods that a scientist could determine if two species of birds are related to each other?

MCQ Options:
a. Analyzing the geographical distribution and studying the coloration of feathers.
b. Examining the wing structure and comparing the DNA sequences.
c. Counting the number of species in each habitat and measuring beak size.
d. Observing mating behaviors and studying the age of fossilized eggs.

Answer 1

Scientists can determine the relatedness of two bird species by comparing their DNA sequences and examining homologous structures, and can illustrate their evolutionary relationships using a cladogram.

Step-by-step explanation:

Scientists can determine if two species of birds are related to each other using several methods. One way they can try to determine whether the two types are the same species is by comparing DNA sequences. If they are not the same species, another method to determine how closely related they are to each other is by examining homologous structures, such as similarities in wing structure. To demonstrate their evolutionary relationship to each other and to other organisms, scientists can create a cladogram. This diagram illustrates the evolutionary paths and common ancestors of the species in question, effectively mapping out their phylogeny based on both morphological and genetic evidence.
