transport: Biology of romantic love

Evidence: 100 • authority: 72

The biology of romantic love has been explored by such biological sciences as evolutionary psychology, evolutionary biology, anthropology, and neuroscience. Neurochemicals and hormones, such as dopamine and oxytocin, are studied along with a variety of interrelated brain systems (including the reward system) which produce the psychological experience and behaviors of romantic love. The study of romantic love is still in its infancy. As of 2021, there were a total of 42 biological studies on romantic love. According to the researcher Enzo Emanuele, in light of the comparative lack of neurochemical studies on the early stage of romance, "it would not be surprising that a diversity of biologic…

Romantic love as regulatory co-option of maternal-bonding circuitry: a testable genetic account.. Romantic love lacks a mechanistic, testable evolutionary account. Prior work notes parallels with mother-infant bonding but leaves the genetic architecture and falsifiable predictions unspecified. We argue that romantic love evolved not through the evolution of new "love genes," but by altering the regulation of existing genes: changing when, where, and under what physiological conditions these genes are active. This regulatory co-option framework generates several falsifiable predictions: (1) a shared genetic basis between maternal bonding and romantic love, (2) the involvement of non-coding,…

Exploring genetic variability and floral trait inheritance in F₁ hybrids from climber × miniature rose crosses.. Potted miniature roses are widely cultivated as popular indoor ornamental plants. Owing to increasing consumer demand, new varieties are introduced to the market each year. Cross-breeding remains the most prevalent method for developing potted miniature roses. In the present study, Rosa noisettiana Thory, a climber rose species, was used as the seed parent, while ten commercially popular miniature rose cultivars (Rosa White Star, Hot Jewel, Rosa Sweet Star, Rosa Bling Love Star, Orange Jewel, Rosa Shining Star, Rosa Lady Star, Orange Romance, Red Romance, and Sparkling Jewel) ser…

Adolescence (from Latin adolescere 'to mature') is a transitional stage of human physical and psychological development that generally occurs during the period from puberty to adulthood (typically corresponding to the age of majority). Adolescence is usually associated with the teenage years, but its physical, psychological or cultural expressions may begin earlier or end later. Puberty typically begins during preadolescence, particularly in females. Physical growth (particularly in males) and cognitive development can extend past the teens. Age provides only a rough marker of adolescence, and scholars have not agreed upon a precise definition. Some definitions start as early as 10 and end…
