Investigating Adaptive Traits in the Sim

Part 1: Evaluating a Claim

Claim: Yellow color is always an adaptive trait in a yellow environment.

Do you agree or disagree with this claim? (circle one)

agree disagree

Part 2: Investigating Environment A in the Simulation

Goal: Gather evidence to support or refute the claim: Yellow color is always an adaptive trait in a yellow environment. Turn to page 28 if you are investigating Environment B.

Do: • Open the Natural Selection Simulation and open the mode: Camouflage.

• Under Biotic Factors: Carnithons, make sure Include Carnithons is selected.

• Under Abiotic Factors, change the Surface-Color slider to Yellow Level 7.

• Press RUN and observe ostrilopes with different color traits for 50 generations. You can also refer to the Traits Histogram Window while the Sim is running.

• After 50 generations, press ANALYZE and compare the color traits in the starting ostrilope population to the population after 50 generations.

Tip: • Do not change the initial ostrilope distribution of traits.

Which ostrilopes were more likely to survive and became more common in the population? Which ostrilopes were less likely to survive and became less common in the population?

Homework: Simulating Changes to Water-Storage Trait Distribution in Thornpalms

Goal: Create an environment where traits for increased levels of water storage become more common in the thornpalm population.

Do:• Open the Natural Selection Simulation and open the mode: Thornpalm Water Storage.

• Under Abiotic Factors, make changes to the rainfall level that you think will make high water-storage traits become more common.

• Press RUN and observe the results over 50 generations.

• Press ANALYZE to compare initial and final histograms.

• If necessary, press BUILD and try again.

• Answer the questions below.

Tip: • Use the Traits Histogram Window in Run to watch the Thornpalm Water Storage Histogram.

What environmental change caused high levels of water-storage traits to become more common? Why do you think this happened?

Investigar rasgos adaptativos en la Simulación

Parte 1: Evaluar una afirmación

Afirmación: El color amarillo siempre es un rasgo adaptativo en un ambiente amarillo.

¿Estás de acuerdo o en desacuerdo con esta afirmación? (encierra una en un círculo)

de acuerdo en desacuerdo

Parte 2: investigar el Ambiente A en la Simulación

Meta: Reunir evidencia que respalde o refute la afirmación: El color amarillo siempre es un rasgo adaptativo en un ambiente amarillo. Pasa a la página 28 si estás investigando el Ambiente B.

Haz lo siguiente: • Inicia la Simulación Selección natural y abre el modo “Camouflage” (Camuflaje).

• Bajo “Biotic Factors: Carnithons” (Factores bióticos: carnithons), asegúrate que “Include Carnithons” (Incluir carnithons) esté seleccionado.

• Bajo "Abiotic Factors" (Factores abióticos), cambia el control deslizante de “Surface-Color” (Color de Superficie) a “Yellow Level 7” (Amarillo Nivel 7).

• Oprime RUN (Ejecutar) y observa ostrilopes con rasgos para color diferentes durante 50 generaciones. También puedes consultar “Traits Histogram Window” (Ventana de Histograma de Rasgos) mientras la Simulación está en ejecución.

• Después de 50 generaciones, oprime ANALYZE (Analizar) y compara los rasgos para color en la población inicial de ostrilopes contra los rasgos en la población después de 50 generaciones.

Consejo: • No cambies la distribución inicial de rasgos de ostrilope.

¿Cuáles ostrilopes era más probable que sobrevivieran y que por lo tanto se hicieran más comunes en la población? ¿Cuáles ostrilopes era menos probable que sobrevivieran y que por lo tanto se hicieran menos comunes en la población?

Tarea: simular cambios a la distribución de rasgos para almacenaje de agua en thornpalms

Meta: Crear un ambiente en el que los rasgos para niveles elevados de almacenaje de agua se hagan más comunes en la población de thornpalms.

Haz lo siguiente:• Inicia la Simulación Selección natural y abre el modo “Thornpalm Water Storage” (Almacenaje

de Agua del Thornpalm).

• Bajo “Abiotic Factors” (Factores abióticos), haz cambios al nivel de lluvia que, en tu estimación, harán que los rasgos para alto almacenaje de agua se hagan más comunes.

• Oprime RUN (Ejecutar) y observa los resultados durante 50 generaciones.

• Oprime ANALYZE (Analizar) para comparar el histograma inicial y el histograma final.

• Si es necesario, oprime BUILD (Construir) e intenta de nuevo.

• Contesta las siguientes preguntas.

Consejo: • Usa “Traits Histogram Window” (Ventana de Histograma de Rasgos) en "Run" (Ejecutar) para

observar el Histograma de Almacenaje de Agua del Thornpalm.

¿Qué cambio ambiental causó que los rasgos para niveles altos de almacenaje de agua se hicieran más comunes? ¿Por qué piensas que sucedió esto?
