Answer:
Distinguishing between Similar Traits
Similar traits can be either homologous structures that share an embryonic origin or analogous structures that share a function.
LEARNING OBJECTIVES
Explain the difference between homologous and analogous structures
KEY TAKEAWAYSKey PointsOrganisms may be very closely related, even though they look quite different, due to a minor genetic change that caused a major morphological difference.Unrelated organisms may appear very similar because both organisms developed common adaptations that evolved within similar environmental conditions.To determine the phylogeny of an organism, scientists must determine whether a similarity is homologous or analogous.The advancement of DNA technology, the area of molecular systematics, describes the use of information on the molecular level, including DNA analysis.Key Termsanalogous: when similar similar physical features occur in organisms because of environmental constraints and not due to a close evolutionary relationshiphomologous: when similar physical features and genomes stem from developmental similarities that are based on evolutionphylogeny: the evolutionary history of an organismmolecular systematics: molecular phylogenetics is the analysis of hereditary molecular differences, mainly in DNA sequences, to gain information on an organism’s evolutionary relationships
