उत्तर
- Giraffe ancestors had variations in neck length.
- Due to scarcity of food, giraffes with longer necks could reach leaves on tall trees more easily.
- Long-necked giraffes were therefore better adapted and had a greater chance of survival.
- They reproduced more successfully and passed the favourable variation to their offspring.
- Over many generations, natural selection resulted in the evolution of the long neck of modern giraffes.
