Question

How did giraffes evolved, as per Lamarck?

Answer 1

Answer:

Lamarck believed that the long necks of giraffes evolved as generations of giraffes reached for ever higher leaves. This sort of evolution, for which Lamarck is most famous today, was only one of two mechanisms he proposed. ... Like Buffon, Lamarck believed that life had begun through spontaneous generation.
