On a very simple level, the answer should be that archaebacteria developped in climates, atmospherical conditions, temperatures, physical and chemical environments that were in some ways different from those that characterize Earth today. So, it is reasonable that planets with conditions like those of Earth when archaebacteria developped might bear some form of life similar to archaebacteria, or evolved from those organisms.
The correct answer of the given question above would be the third option. The statement that depends on the absolute dating of events is this: The oldest Earth rocks are 3.9 billion years old. Absolute dating is the method of determining the specific date of an archaeological or paleontological artifact. In contrast, relative dating is just the determining of the relative order of events and not necessarily the estimated age of the artifact.
Answer:
Sexual reproduction involves two parents and the joining of male and female gametes during fertilisation. The offspring inherit a mixture of genes from both parents, so are different to each other and their parents. In asexual reproduction there is only one parent. The offspring are clones of the parent and each other.
