@RAT - The biological difference between males and females is not external genitalia. It is the size and complexity if the gamete.
@Perry - 'Information' is a metaphor for what DNA does. It is just chemicals doing their thing.
If we had not a single fossil DNA would prove the fact of evolution beyond all doubt.
Here are just a few examples of the genetic evidence for evolution....
#1 Protein Functional Redundancy
Comparing the sequences of amino acids in ubiquitous proteins confirms the relationship between all living things.
#2 DNA Functional Redundancy
Comparison of the DNA that codes for the amino acids of ubiquitous proteins predicts the tree of life with an astonishing degree of accuracy.
#3 ERVs
Endogenous retroviruses that infected our ancestors are found in the same place of the genome of our closest primate cousins.
#4 Smelly Genes
Hundreds of broken genes that used to code for olfactory receptors in our ancestors are still found in our genome.
#5 Vitamin C
Why humans can no longer make their own vitamin C and what that tells us about our species' history.
#6 Human Chromosome 2
Our second biggest chromosome is made up of two of our ancestors' chromosomes stuck end-to-end.
#7 Human Egg Yolk Gene
Humans and our primate cousins have the genes for making vitellogenin and they are all broken in the same way.
#8 Jumping Genes
Bits of parasitic code called ALU elements prove our common ancestry with primates.
#10 Non-Coding DNA
In common with many other species huge amounts of our genome originated as copying errors.
