Question

BlackTom AI · Accepted Answer

The question concerns analogous anatomical structures in two different species and what their characteristics are.
Option 1: 'have similar functions.' This is the hallmark of analogous structures: different evolutionary origins but similar selective pressures lead to similar roles or functions in the organism. This option aligns with the concept of analogy.
Option 2: 'are derived from the same ancestral structure.' This describes homologous structures, not analogous ones. Homology involves shared ancestry and often similar internal bone patterns, even if the functions diverge; thus this statement is inaccurate for analogous structures.
Option 3: 'were formerly useful, but are now useless.' This statement describes vestigial or atrophied structures, not the defining feature of analogy. It does not capture why analogous structures are similar in function.
Option 4: 'have different functions.' By definition of analogous structures, they perform similar functions, not different ones, so this contradicts the concept and is incorrect.
