Spontaneous generation, the hypothetical process by which living organisms develop from nonliving matter.
Explanation:
In 1668, Francesco Redi, an Italian scientist, designed a scientific experiment to test the spontaneous creation of maggots by placing fresh meat in each of two different jars. One jar was left open; the other was covered with a cloth. Days later, the open jar contained maggots, whereas the covered jar contained no maggots. He did note that maggots were found on the exterior surface of the cloth that covered the jar. Redi successfully demonstrated that the maggots came from fly eggs and thereby helped to disprove spontaneous generation.
The quiver tree faces various problems due to climate change and drought periods. The population of this plant tries to avoid the unfavorable environmental conditions by shifting their growing range towards the poles, or more precisely away from the heat of the equator.
