Evolution in Bacteria may be similar to some Eukaryotes.

According to a source at Sciencedaily researchers in a April 6 paper have discovered that bacteria may be going to through an evolutionary process much more similar to Eukaryotes.  MIT's researchers from there department of Civil and Environmental Engineering have discovered evidence that beneficial mutations can progress through multiple organisms in a population at there own piece.  This process takes place by the genes exchanging between two bacteria. The way that the researchers are able to deal with conflicting results is that once the exchange has taken place the bacteria's recombination frequency drops in till the recombination stops completely. Eventually leading to all the bacteria existing in population of cloning individuals. This shows that the bacteria really go through a process similar to Eukaryotes.  These ideas show that two of the Earth's major organism have very similar method of evolution.


The second part of the paper deals about the implications of what the idea of how evolution works in bacteria may change how we view them. The general way bacteria are view is as ecological populations. Since the previous view of bacteria is as clones calling them species doesn't make any sense at all. However, now that this new evidence has been brought to the forefront. Bacteria exchange genes and may create new types of completely different individuals which may give warrant to the term being used for Bacteria.
