This theory is also referred to as the theory of beauty preference selection. One example is the beautiful but cumbersome tail of a male Peacock: surely, this tail was more of a hindrance than a help to survival if a male was suddenly ambushed by a tiger in a jungle.ĭarwin proposed that bird’s beautiful appearances could be better explained by the theory of ‘sexual selection’, whereby male birds’ characteristics were selected by female birds’ beauty preferences or tastes (Darwin, 1871). However, about 20% of birds’ appearances cannot be explained by this theory. According to this theory, we can explain most birds’ appearances by flight performance, species isolation, camouflage, and threat.

This completes the link between beauty preference selection and natural selection and can explain the diversity of colours, shapes, and behaviours used in mating rituals.ĭarwin’s (1859) original theory of natural selection states that certain characteristics were selected by nature because they enabled an individual to better survive in a particular environment. First, nature or needing relationships selected female birds’ beauty preferences (or tastes), which later selected male birds’ beautiful features. Chenguang Lu, Associate Professor at Changsha University, suggests that male birds’ beautiful features are based on mimicry of essential food resources and environments. However, British naturalist Alfred Russell Wallace strongly objected to this idea, saying it adds another principle to the principle of natural selection and hence betrays Darwinism. It was conceived as a companion to natural selection to help explain birds’ colourful plumage and behaviours for beauty. I know fall is almost here, but these bars are almost enough to make me wish for an extra week of summer.The core idea of Charles Darwin’s theory of sexual selection is beauty preference selection. These bars are a little sweet, a little tart and a lot delicious. To take the bars over the top, fresh blueberries are folded into the filling, providing a pop of flavor and color. I haven’t used sweetened condensed milk much, and I had no idea it would create such a smooth, rich filling.

They start with a thick, lemony graham cracker crust that’s topped with a tart, even more lemony filling.

(Beware the pumpkin posts that await next month.) These lemon bars remind me a lot of cheesecake bars. Since I know I have little will power when it comes to pumpkin, it was imperative that I make these and soon. I put off making them until I realized that as soon as I made my first pumpkin dessert, there was no going back to summer ones. They were such a hit at her party that I knew I’d have to make them again before summer’s end.

I first made these lemon bars for my friend Erin’s birthday. On a brighter note, that means there’s still time to enjoy summery desserts like this one. Sadly, it’s still August, which means the unofficial start of fall is still over a week away. Pumpkin, of course, is the reason I really look forward to fall every year. Fall weather is my favorite for several reasons, but one of the main ones is that it’s warm enough for sandals but cool enough for jeans and a cardigan. I am unbelievably ready for fall and all the things that come with it.
