I am not sure about this one. This is a crab spider going by the fact that front four legs are way longer than the hind four. It has a human face like black pigment on it which resembles some morphs of Theredion grallator sp. Both of these have red and black variants and apparently adhere to mendelian genetics in allele propagation. Also, T. grallator has pink pigmentation in the distal segments of the legs. This most likely is a male as females from these species don't move around much and would not like to be noticed in their comfy house under a leaf. The males on the other hand probably use this to ward of predators. We perceive this as a face but I don't know the actual selection pressure in the wild that has led to this morphology. This would be an interesting phenotype to study migration and rapid evolution among spiders. Theredion sp. are actually used for this sort of study but not sure about clown faced crab spiders. Funny, how we rarely notice what marvelous creatures pass us by everyday. #arachnids #arthropod #spider #evolution #sexualselection https://www.instagram.com/p/CSMZ9k4pqvv/?utm_medium=tumblr

Devaneios de quarentena: Munhoz e Mariano dando aula de seleção sexual

A letra da música Camaro Amarelo, de Munhoz e Mariano, dá boas discussões a respeito de esteriótipos femininos e masculinos, porém ignorando a espécie do eu lírico e prestando atenção apenas nos fenômenos biológicos envolvidos ela me parece muito boa também para discussão de ecologia e de seleção de parceiro sexual. Então, olhando apenas o fenômeno biológico envolvido não vou me referir a nenhuma espécie específica, assim quando disser macho será o sexo que produz os espermatozóides e quando disser fêmea será o sexo que produz o óvulo, não estarei me referindo ao homem ou à mulher.

A canção apresenta dois momentos um antes e um depois da aquisição do tal camaro amarelo.

Pré-camaro

“Quando eu passava por você Na minha CG, você nem me olhava Fazia de tudo pra me ver, pra me perceber Mas nem me olhava”

Num primeiro momento o macho não possui os ornamentos necessários para atrair as fêmeas e tenta compensar com estratégias de cortejo malsucedidas. Neste cenário o macho é competidor (sexual) fraco e perde o acesso ao recurso (fêmeas/sexo).

Pós-camaro

“Aí veio a herança do meu véio E resolveu os meus problemas, minha situação E do dia pra noite fiquei rico Tô na grife, tô bonito, tô andando igual patrão”

Mas então ele lucra com o falecimento do pai (o que também daria uma boa discussão a respeito de cuidado parental) e consegue adquirir os ornamentos sexuais necessários para conquistar as fêmeas. Isso torna ele um competidor (sexual) forte, capaz de alcançar com facilidade os recursos (fêmeas/sexo).

“E agora você vem, né? Agora você quer? Só que agora vou escolher Tá sobrando mulher”

Agora sendo um competidor forte o macho ganha o poder de selecionar os recursos que irá consumir. E agora as fêmeas que antes competiam entre si por outros machos, agora também competirão pelo garanhão órfão.

Alguém poderia sugerir que ele poderia simplesmente aproveitar todas as oportunidades de sexo disponíveis, porém o sexo é um investimento que requer um grande gasto de energia (e de tempo), o que faz dessa estratégia pouco vantajosa .

Agora, voltando para a espécie que está realmente sendo protagonista da história. Sejamos francos, tanto o papel de homem disputando para seduzir mulher quanto o papel de mulher disputando homem são igualmente patéticas, o que faz dessa letra uma grande vergonha (apesar de biologicamente interessante). É importante esclarecer que apesar de sermos uma espécie moldada pela biologia (como todos os seres vivos), também somos moldados pela cultura e ambos os fatores se complementam nos nossos comportamentos. Então não pense de alguma forma que estou confirmando que os homens disputam a atenção de mulheres com dinheiro e nem que as mulheres disputam por homens com dinheiro. Os critérios de seleção sexual humano são muito mais complexos que isso, e acredito que menos capitalista também.

#Repost @natgeo ・・・ A photo for a book project in evolution...the beautiful eyes of Bella. The earliest human ancestors came from the continent of Africa, as #primates adapted and then branched off into many different species that eventually became our modern day human beings appeared. Since the equator cuts directly through the continent of Africa, the countries there receive almost direct sunlight, with ultraviolet rays, and the warm temperatures it brings pressured for the natural selection of dark skin color. Pigments, like melanin in the skin, protect against these harmful rays of the sun. Individuals with darker skin live longer and they would reproduce and pass down the dark skinned genes to their offspring. #Naturalselection for the lighter eye colors are linked to the relaxation of selection for darker skin tones. As human ancestors began to migrate to various places around the world, the pressure for selection of dark skin color was not as intense. These much higher latitudes afforded different seasons with much less direct sunlight , like near the equator, the selection pressure was no longer as intense, genes were more likely to #mutate. The color of human #eyes is not dictated by a single gen many it of the other traits. It is instead considered a polygenic trait, meaning there are several different genes on various chromosomes that carry information about what eye color an individual should possess. These genes, when expressed, then blend together to make various shades of different colors. Relaxed selection for dark eye color also allowed more mutations to take hold. This created even more alleles available to combine together in the gene pool to create different eye colors. #Sexualselection may also explain some of the different eye colors that have popped up over time. Mating, in humans, tends to be non-random and as a species, we are able to choose our mates based on desirable characteristics. Some individuals may find one eye color much more appealing over another and choose a mate with that color of eyes. Then, those genes are passed down to their offspring and continue to be available in the gene pool. @robertclarkphoto @thephotosociet

Stag beetle (Lucanidae). So neat 😄🌏🌋This is a male, you can tell because of their huge mandibles that they wrestle other males with! #SexualSelection (at Starkville, Mississippi)

Today, my book entitled “The Descent of Man, and Selection in Relation to Sex” was published. This book explains my theories based on human evolution from primates and the process of sexual selection. Sexual selection is the manner in which animals and humans decide which of their species to mate with to produce the strongest offspring with the best characteristics and genes.
