The below linked article is fascinating and the researcher is attempting to answer the question, "how are two dramatically different organisms, in this case male and female, produced from a single genome"?
The article states that the "males and females hatch out of their eggs at the same size, but then go down different paths; during their yearlong development into adults, the males grow up to three times larger than the females". The article goes on to state, "This implies that brothers and sisters, who share many of the same genes, are doing something different with their genes as they mature".
The article continues by stating, "By measuring the expression of thousands of individual genes at different points in development, they found that sex differences in gene expression increased dramatically with age, as males and females diverged in size. This shows that there is a huge amount of flexibility in what can be done to reach different endpoints from the same DNA blueprint".
In addition, "We also found that many of the patterns of gene expression that are typical of adult males can be induced by treating females with the hormone testosterone, putting the pieces together, we suggest that, by virtue of their widespread effects on gene expression throughout development, hormones such as testosterone play a key role in shaping the genetic basis of traits, which will in turn influence how these traits evolve in response to natural and sexual selection."
Many who practice the religion of microbes to man evolution will try and promote their faith by showing the great variety of species on Earth. Some of this variation is a result of mutations, but a great deal of it was built into the genome by design! As this article lays out, genomes have the ability to become either male of female depending on how the genetic programming is expressed or executed. It is a testament to the complexity and capability of the programming that runs life! Is it logical that this came about through random mutations and luck? No - a very intelligent designer is the only thing that makes rational sense.
