good-genes and sexy-sons hypotheses focus on direct benefits associated with female choice.

The sexy-sons hypothesis is similar however it posits that females will choose the most attractive males to mate with so that those

but the most accepted idea is the abiotic evolution of organic molecules from primordial Earth conditions. Details about the nature of this evolution are still debated‚ but the general idea can be explained in a four-stage hypothesis. In this four-stage hypothesis‚ the first stage was the abiotic formation of organic molecules‚ such as amino acids and nucleotide monomers. The idea that organic molecules can be formed abiotically was based on the fact that the early Earth was abundant with elements
