Answer:
one common ancestor
Explanation:
Although Darwin’s theory is often described as the theory of evolution by natural selection, most commentators recognize that common ancestry (the idea that all organisms now alive on earth and all present day fossils trace back to one or a few “original progenitors”) is an important part of the Darwinian picture.
Answer: The options are not given, here are the options.
A. One species is much better competitor than the other.
B. Periodic disturbances allow for coexistence.
C. Two species tended to use different resources.
D. The two species experienced interference competition and not exploitative competition.
The correct option C.
Two species tended to use different resources.
Explanation:
From Gause experiments on competing paramecium pairs, He found out that most times both species persisted and sometimes only one did because the two species uses different resources.
Organisms normally compete for limited resources in order to survive and one intend to compete well while other suffer. Both in the case of competing paramecium pairs, the pair use different resources which make the to persist and survive well. Once the resource of one finishes, the other one will persist because it is still surviving on its available resources.
