The phenomenon which Lamarck fails to explain is
1 Exceptionally long neck of giraffe
2 An intellectual having a dull son
3 Loss of vision in cave dwelling mammals
4 Absence of all the four limbs amongst Amphibians
Explanation:
Some amphibians are devoid of all of the four limbs, it is explained by Lamarckism. The ancestors of giraffe were bearing a small neck and fore-limbs and were like horses. But as they were living in places with no surface vegetation, they had to stretch their neck and fore-limbs to take the leaves for food, which resulted in the slight elongation of these parts, it is explained by Lamarckism. The ancestors of cave dwellers had normal eye sight. On account of living under continuous dark conditions, the animal lost their power to see, it is explained by Lamarckism. However, Dull progeny of Nobel Prize winners cannot be explained by Lamarckism. It could not explain that why the kids of Nobel Laureates have dull children.

Darwin believed that the giraffe has long neck because
1 They were always like that
2 The catastrophes eliminated short necked forms
3 Its ancestors stretched their needs to get food
4 Ancestral giraffes with slightly longer necks than others got more food and left more food surviving adapted offsprings
Explanation:
Charles Darwin was the first to propose that giraffes evolved into the elegantly longnecked creatures they are because successive generations realized that extra vertebrae helped them get access to tender leaves on top of trees.

According to Lamarck, a giraffe has a long neck because
1 A creator designed it that way.
2 Catastrophes eliminated short-necked forms.
3 Its ancestors stretched their necks to get food.
4 Ancestral giraffes with slightly longer necks than others got more food and left more surviving offspring.
Explanation:
According to Lamarckism an organism can pass on the characteristics that it acquired during its lifetime. According to Lamarck, a giraffe has a long neck because its ancestors stretched their necks to get the food.

Lamarckism was not well accepted at todays time because
1 His mechanism lack reasonable evidences
2 Organisms pass down traits through predetermined genetic information, not based on environmental adaptations during their lifetime.
3 Weismanns experiment disproved his theories
4 All the above
Explanation:
Because it was tested and found to be wrong. Same reason chemists don't accept the phlogiston theory of fire. Or astronomers the geocentric theory of the Solar System. Or doctors the "bad air" theory of malaria. It's not accepted because it was wrong, and demonstrated as such.
