:The difference between the two is based on the symbiotic relationship.  The examples should provide a difference, whales and fish having similar shaped bodies for moving through water would be convergent evolution whereas a tick and a deer evolving together where the tick is only found on a certain species of deer and has selective traits for that host, such as additional enzymes to help break down a protein found only in that deer species.--[[User:Tims|TimS]] 14:37, 24 May 2007 (EDT)

This is very misleading.  Evolution does not require an addition of new genetic material to occur, a rearrangement of current material can produce drastic results.  Let’s look at sickle cell anima for example.  Its primary cause is due to a hydrophilic glutamate (Glu) being substituted by the hydrophobic valine (Val), which reduces the solubility of ß-globin. In this case, this mutation causes hemoglobin to form linear polymers linked by the hydrophobic interaction between the valine groups causing sickle-cell deformation of erythrocytes.  This mutation is genetically passed between heterozygous carriers and helps to fend off the protozoa that cause malaria.  Homozygous carriers tend to have complications due to a reduction of O2 in the blood volume.  This is all due to a single point mutation of a codon that switches adenine to uracil during transcription, the DNA has the point mutation of an adenine changing to a thymine.  This is not based off of new genetic material but off existing genetic material.  The genomic size is the same as before since there was not an addition of nucleotides.  Many proponents of evolutionary theory use the "increase of genetic material" argument but it is considered unfounded since complexity is not proportional to genomic size, just the order in which it is arranged.--[[User:Tims|TimS]] 15:08, 24 May 2007 (EDT)
