However, when it came to the animals which were referred as the “lowest class” would Darwin began to debate thatįemales possess sufficient intelligence to appreciate beauty this was discovered in the following species: insects, Darwin came to realising that animals would need a human-like sense ofĪesthetics for sexual selection to operate this lead to further research of great lengths. Darwin originally didn’t take into consideration that female animals Displayable traits to attract femalesĪre shown within male-male combat this suggests fighting for dominance which could also result in the death of theĬharles Darwin developed and proposed many theories on evolution and the far-reaching effects on science and the Male animals would have to meet the female’sĮxpectations and preference before she would allow the mating process to occur. Provide protection to her and any possible offspring’s as well. Females would also want a dominant male who will Traits will progress further within future, successful generations. An increased survival rate suggests that their Traits this will increase the survival rates of their possible offspring’s. Females will generally want a male that have certain These traits usually depend on the species of animal. Certain males would provideįemales with a variety of food sources, suitably built nests, colouration and other “gift offerings”. Females will generallyĬhoose males who can provide sufficiently for herself and any possible offspring’s. The following traits that affect a female animal’sĭecision are signal attractiveness to the other sex and competitive rank within the same sex. Sexual selection provides around 2 types of mechanisms overall: forĮxample, mate choice and competition for mates.įemales are generally the choosy sex when it comes to mating. To as intra-specific reproductive competition. Mating within the future alongside survival opportunities. Select specific admirations from their mate, to pass onto their offspring’s this gives the offspring an opportunity in Sexual selected traits allow an individual to These characteristics can increase any mating opportunities. These characteristics are known as sexual selected traits. Sexual selection allows the evolution of certain noticeable physical traits: for example, distinctive colouration, The preference is decided by one sex (preferablyįemale) searching for certain characteristics within individuals of the other sex (usually males). Sexual selection is natural selection through an animal’s preference.
