What was the Lamarck’s explanation for long necked giraffes?
- Stretching of necks over many generation
- Short neck suddenly changed into long one
- Natural selection
- Mutation

B-Neck of giraffe lengthen a little by making efforts to each the leaves
C-Offspring with longer neck were produced
D-Further, the neck of offsprings length in when the lower branches were consuming
E-Very long neck of giraffe was developed after the number of generations
Lamarck explanation for long necked giraffes The ancestors of giraffe were bearing small neck and fore limbs were like horses. But as they were living in places with no surface vegetation, they had to stretch their neck and forelimb to take their food, which resulted in the slight elongations of these parts. Whatever they acquired in one generation was transmitted to next generation with the result that race of long necked and long forelimbed animal was developed
