¿Cómo explicaría Lamarck el origen y la expansión de estas bacterias resistentes? ¿Cómo explicaría
Anuta_ua [19.1K]

La teoría de la evolución de Lamarck se basa en la capacidad de los organismos para cambiar físicamente debido a las adaptaciones en su entorno para garantizar su supervivencia. Esto es evidente en la propagación de los determinantes de resistencia a los antibióticos entre las bacterias. La capacidad de las bacterias para desarrollar nuevos mecanismos de resistencia para sobrevivir a los antibióticos radica en su capacidad para adquirir genes que los ayuden a este respecto a través de la transferencia horizontal de genes y la adquisición de plásmidos. Mecanismos como bombas de eflujo y plásmidos les ayudan a sobrevivir en medio de antibióticos. Transmiten estos materiales genéticos a sus descendientes, lo que garantiza que continúen sobreviviendo y no se extingan a pesar de la presencia de antibióticos.

El dawrnismo claramente reclama la selección natural. Por lo tanto, si un organismo no evoluciona o adquiere características especiales para ayudarlo a adaptarse, competir y sobrevivir en su entorno, se extingue. Solo aquellos que adquieren estas habilidades sobreviven y se reproducen en el medio ambiente.
