What is the ultimate source of genetic variation and the basis for the diversity of life on earth?
Mutations. These have quite a few different causes. Sexual reproduction is a "more recent source" {beginning 600 million years ago} of genetic variability. The process of sharing genetic information, coupled with the random crossing and mixing of genetic information during the creation of a new organism, leads to another source of genetic variability.

What is the ultimate source of genetic variation and the bases for the diversity of life on earth?

What is the primary source of genetic variability in prokaryotes?
The primary source of genetic variability in prokaryotes is through horizontal gene transfer mechanisms such as transformation, transduction, and conjugation. These processes allow prokaryotes to acquire new genetic material from other bacterial cells or environments, leading to genetic diversity within populations.
What process provides the genetic variability that natural selection acts on during evolution?
The ultimate source of variation is mutation. However, recombination, or crossing over, can produce enormous amounts of variation by shuffling alleles into different combinations. Combined, the two processes produce the variation upon which natural selection can act, and which results in evolution.
What are the sources of genetic variation in bacteria and humans?
The most important source of variability in bacteria is mutation.
What is the ultimate source of variation needed for evolutionary change?
mutation
What is the ultimate source of water cycle?

What is the ultimate source of energy for ecosystems?
The sun is the ultimate source of energy for almost all earth ecosystems.
