Read the provided scenario about two different species of birds. Determine whether the similarities between their wing structures are homologous or analogous and explain your reasoning. What factors would help you determine if the similarities in wing structures between two bird species are homologous or analogous?
Homologous, due to shared ancestry
Analogous, due to similar environmental pressures
Cannot be determined without genetic information
Both homologous and analogous depending on other factors

How do homologous and analogous structures differ from each other?
Homologous structures have similar anatomy but different functions, while analogous structures have different anatomy but similar functions.
Homologous structures are found only in vertebrates, while analogous structures are found only in invertebrates.
Homologous structures are a result of convergent evolution, while analogous structures are a result of divergent evolution.
Homologous structures can perform the same functions if they are from closely related species, while analogous structures cannot.

Imagine you are a scientist studying different animal species. How would you use the knowledge of homologous, analogous, and vestigial structures to determine the evolutionary relationships between these species?
By comparing the DNA sequences of the species
By observing the behavior of the species in their natural habitat
By analyzing the physical structures and their functions to infer common ancestry
By measuring the geographical distances between the habitats of the species
