Detailed explanation-1: -If two modern organisms are distantly related in an evolutionary sense, then one should expect that… A1. they should share fewer homologous structures than two more closely related organisms.
Detailed explanation-2: -Homologous features If two or more species share a unique physical feature, such as a complex bone structure or a body plan, they may all have inherited this feature from a common ancestor. Physical features shared due to evolutionary history (a common ancestor) are said to be homologous.
Detailed explanation-3: -Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species’ relatedness.
