Question

select the correct answer.

the images show the wings of a bat and a bee. from this evidence, what can you conclude about the evolutionary relationship between these organisms?

• the wing structures of the bat and the bee are different, indicating they didnt inherit wings from a common ancestor.
• the wing structures of the bat and the bee are different, indicating they inherited wings from a common ancestor.
• the functions of bat wings and bee wings are the same, indicating they obtained wings from a common ancestor.
• the functions of bat wings and bee wings are different, indicating they didnt obtain wings from a common ancestor.

Explanation:

Analizar las estructuras de las alas

Using the Analogous Structures and Homologous Structures knowledge points

• Las alas de un murciélago (mamífero) están formadas por huesos internos cubiertos de piel, mientras que las alas de una abeja (insecto) son membranas quitinosas sin soporte óseo.
• Al tener orígenes embrionarios y estructuras anatómicas internas completamente diferentes, no provienen de un ancestro común con alas.

Evaluar la relación evolutiva

Using the Analogous Structures knowledge point

• Estas estructuras son estructuras análogas: realizan la misma función (vuelo) pero evolucionaron de forma independiente debido a presiones selectivas similares.
• Por lo tanto, la diferencia estructural indica que no heredaron las alas de un ancestro común.

Evaluar las opciones de respuesta

• Opción 1: "The wing structures of the bat and the bee are different, indicating they didn't inherit wings from a common ancestor." (Correcta, describe con precisión que las diferencias estructurales demuestran que no heredaron las alas de un ancestro común).
• Opción 2: "The wing structures of the bat and the bee are different, indicating they inherited wings from a common ancestor." (Incorrecta, las diferencias estructurales indican lo contrario).
• Opción 3: "The functions of bat wings and bee wings are the same, indicating they obtained wings from a common ancestor." (Incorrecta, la función similar se debe a evolución convergente, no a un ancestro común con alas).
• Opción 4: "The functions of bat wings and bee wings are different..." (Incorrecta, las funciones son las mismas: volar).

Answer:

• (A) The wing structures of the bat and the bee are different, indicating they didn't inherit wings from a common ancestor. (Correct answer)
• (B) The wing structures of the bat and the bee are different, indicating they inherited wings from a common ancestor.
• (C) The functions of bat wings and bee wings are the same, indicating they obtained wings from a common ancestor.
• (D) The functions of bat wings and bee wings are different, indicating they didn't obtain wings from a common ancestor.
