Resumen
La selección sexual es compleja, especialmente en las hembras. Estudios recientes revelan que la competencia femenina y la elección de pareja impulsan una selección sexual significativa, a veces invirtiendo las diferencias sexuales típicas.
Área de la Ciencia:
- Biología evolutiva Biología evolutiva.
- Ecología del comportamiento ecología del comportamiento.
- Selección sexual La selección sexual.
Sus antecedentes:
- La investigación de la selección sexual se ha centrado tradicionalmente en los hombres.
- Los caracteres sexuales secundarios en los machos son complejos.
- La selección sexual femenina ha sido poco estudiada.
Objetivo del estudio:
- Para resaltar la creciente evidencia de la selección sexual en las mujeres.
- Discutir las implicaciones de la competencia femenina y la elección de pareja.
- Para explorar el impacto en las diferencias sexuales en el comportamiento y la morfología.
Principales métodos:
- Revisión de estudios recientes sobre la selección sexual femenina.
- Análisis de la competencia intrasexual entre las hembras.
- Examen de las dinámicas de elección de pareja masculina.
Principales resultados:
- La competencia intrasexual en las hembras es común.
- La elección de la pareja femenina influye significativamente en el éxito reproductivo.
- Los casos extremos muestran inversiones en las diferencias sexuales típicas.
Conclusiones:
- La selección sexual femenina es una poderosa fuerza evolutiva.
- Comprender la elección femenina es crucial para la teoría evolutiva.
- La selección sexual en las hembras puede alterar los patrones de comportamiento y morfológicos.

01:06Natural Selection and Mating Preferences
The principle of natural selection posits that organisms better adapted to their environment are more likely to survive and reproduce. This principle is closely intertwined with mating preferences, a key aspect of sexual selection, which evolutionary psychologists believe is driven by instincts to propagate one's genes. Such instincts significantly influence mating behaviors and preferences between genders.

01:20Mate Choice
Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.
01:46Types of Selection
Natural selection influences the frequencies of particular alleles and phenotypes within populations in several different ways. Primarily, natural selection can be directional, stabilizing, or disruptive. Directional selection favors one extreme trait and shifts the population towards that phenotype while selecting against individuals displaying alternate traits. Stabilizing selection favors an intermediate trait with a narrow range of variation. Deviation from the optimal phenotype towards an...
02:45The Ratio of X Chromosome to Autosomes
In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.

01:21Frequency-dependent Selection
When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.Positive Frequency-Dependent SelectionIn positive...
02:19The Y Chromosome Determines Maleness
The Y chromosome is a sex chromosome found in several vertebrates and mammals, including humans. In addition to 22 pairs of autosomes, the human males have one X chromosome and one Y chromosome. In these organisms, the presence or absence of the Y chromosome determines the development of male traits.
Evolution
Around 300 million years ago, the two sex chromosomes diverged from two identical autosomal chromosomes. Over time, the Y chromosome has lost most of its genes, shrinking in size. Today,...
