Birdsong is not all about sexual selection: Female birds sing much more often than previously thought
In 71 percent of all songbird species with available data, the female sings, too. This is remarkable because in the wake of Darwin’s theory of evolution, birdsong has generally been seen as a characteristic of male birds, allowing them to compete with other males and attract females. The exciting question now is how females apparently repeatedly lost their song in the course of evolution. Why did they stop singing in some lineages, but not in others?
I got a straight A (1,0) in my “Introduction to Psychological Research Methods” exam. Naisu. :3
My new mentee will arrive on Friday, and I can’t wait to pick her up from the trainstation.
"Beauty is terror. Whatever we call beautiful, we quiver before it."
"You are a sentence
and I am a semicolon
begging you to go on."
"The planet does not need more successful people. The planet desperately needs more peacemakers, healers, restorers, storytellers and lovers of all kind."
"But your best friend is still your best friend. Even from half a world away. Distance can’t sever that connection. Best friends are the kind of people who can survive anything. And when best friends see each other again, after being separated by half a world and more miles than you think you can bear, you pick up right where you left off. After all, that’s what best friends do."
"It turns out procrastination is not typically a function of laziness, apathy or work ethic as it is often regarded to be. It’s a neurotic self-defense behavior that develops to protect a person’s sense of self-worth.
You see, procrastinators tend to be people who have, for whatever reason, developed to perceive an unusually strong association between their performance and their value as a person. This makes failure or criticism disproportionately painful, which leads naturally to hesitancy when it comes to the prospect of doing anything that reflects their ability — which is pretty much everything."
Oh sweety, this is nothing. One time I was combing my hair but I got interrupted by the telephone. After the phone call was done I wanted to go on combing, but - surprise! My comb had magically…
No, you see, it happened to be a very light plastic comb, and as my hair used to be very long at that time I didn’t feel so much as a weight difference. At least it was a beautifully carved one, so it didn’t look too stupid, but… well. That’s me being dedicated to something (or becoming quickly unfocused. Choose one way of interpretation.)
