A gradual origin, with each step favored by natural selection, is possible (Kondrashov 1997). The earliest steps involve single-celled organisms exchanging genetic information; they need not be distinct sexes. Males and females most emphatically would not evolve independently. Sex, by definition, depends on both male and female acting together. As sex evolved, there would have been some incompatibilities causing sterility (just as there are today), but these would affect individuals, not whole populations, and the genes that cause such incompatibility would rapidly be selected against.
Many hypotheses have been proposed for the evolutionary advantage of sex (Barton and Charlesworth 1998). There is good experimental support for some of these, including resistance to deleterious mutation load (Davies et al. 1999; Paland and Lynch 2006) and more rapid adaptation in a rapidly changing environment, especially to acquire resistance to parasites (Sá Martins 2000).
Great! I see you have copying and pasting down pat. That in no way answers my question though, so strawman argument and try again.
The question is why would we even have a sex drive or a will to live or an immune system?
Just because of nothing and for no reason? How would nothingness care if our species survived?
Also, we have discovered that there are approx 200 billion different galaxies. Do you really think humans are the highest form of intelligence in 200 billion galaxies?

It is totally relevant, so answer the question and stop hedging.

https://en.wikipedia.org/wiki/Epigenetics
This second language is constantly evolving, and in fact can change in ONE generation, depending on the experience(s) of the progenitor.
"The term also refers to the changes themselves: functionally relevant changes to the genome that do not involve a change in the nucleotide sequence. Examples of mechanisms that produce such changes are DNA methylation and histone modification, each of which alters how genes are expressed without altering the underlying DNA sequence. Gene expression can be controlled through the action of repressor proteins that attach to silencer regions of the DNA. These epigenetic changes may last through cell divisions for the duration of the cell's life, and may also last for multiple generations even though they do not involve changes in the underlying DNA sequence of the organism;[5] instead, non-genetic factors cause the organism's genes to behave (or "express themselves") differently.
One example of an epigenetic change in eukaryotic biology is the process of cellular differentiation. During morphogenesis, totipotent stem cells become the various pluripotent cell lines of the embryo, which in turn become fully differentiated cells. In other words, as a single fertilized egg cell – the zygote – continues to divide, the resulting daughter cells change into all the different cell types in an organism, including neurons, muscle cells, epithelium, endothelium of blood vessels, etc., by activating some genes while inhibiting the expression of others.
"Epigenetic inheritance adds another dimension to the modern picture of evolution. The genome changes slowly, through the processes of random mutation and natural selection. It takes many generations for a genetic trait to become common in a population. The epigenome, on the other hand, can change rapidly in response to signals from the environment. And epigenetic changes can happen in many individuals at once. Through epigenetic inheritance, some of the experiences of the parents may pass to future generations. At the same time, the epigenome remains flexible as environmental conditions continue to change. Epigenetic inheritance may allow an organism to continually adjust its gene expression to fit its environment - without changing its DNA code."
Dumbass opened a can of worms that refutes her nonsense. LOL ... and about which she knows nothing.

But just you wait. She's gonna solve the mysteries of the universe for us.
All you do is present strawman arguments and make yourself look like even more of a foolish idiot than you already have before. Try harder to figure out what it is that we are actually discussing.
