Answer and Explanation:
a. According to Lamarck, the origin of the long hind legs of the Ord's kangaroo rat is acquired due to extensive use of the muscle legs to jump. Such physical characteristics could be transmitted to future generations. This theory is called Neo-Lamarckism.
b. Darwin, on the other hand, theorized that in a population of Ord's kangaroo rat, there was an individual whose characteristics, long tail and hind legs, had more chances of escaping its predator and, consequently, could survive and reproduce. This theory is called Darwinism.
Answer:
True
Explanation:
<em>Aristotle initially thought that life arose spontaneously and he backed this up by showing that a lump of meat left uncovered in a glass jar spontaneously produced maggots.</em>
The spontaneous generation theory was later disproved by another scientist, Francesco Redi. He showed that a covered jar containing a lump of meat will not spontaneously produce maggots unless flies are allowed to perch and lay their eggs on the meat. The eggs of the flies give rise to the maggots and not the meat.
<u>It thus showed that new life does not arise spontaneously but rather through development and reproduction.</u>
