Evolution: The Paradox of Sperm Leviathans
نویسنده
چکیده
Sexual selection theory predicts that sperm competition will push males to produce more, smaller sperm. Paradoxically, in the fruitfly Drosophila bifurca sperm competition is rife but males produce few, giant sperm--the largest known. A recent study reconciles the evolution of giant sperm with theory.

I-3: Reactive Oxygen Species: A Dilemma for
Spermatozoa are very special cells and constantly exposed to the interphase between oxidative stress through high amounts of reactive oxygen species (ROS) and leukocytes, and reduction by means of scavengers and antioxidants. Considering the very special functions of spermatozoa as being the only cells with such high polarization and exerting their functions outside the body, even in a differen...
متن کاملComplex sperm evolution.
A world without sexual selection would be a somber place, lacking the rich medley of stimulating sights, sounds, and smells that help individuals win the evolutionary prize of reproductive success. Sexual selection was Darwin’s second great idea (1), and we recognize it as a potent and widespread evolutionary force that probably interacts across the whole genome (2). We also recognize that sexu...
متن کاملBertrand’s Paradox Revisited: More Lessons about that Ambiguous Word, Random
The Bertrand paradox question is: “Consider a unit-radius circle for which the length of a side of an inscribed equilateral triangle equals 3 . Determine the probability that the length of a ‘random’ chord of a unit-radius circle has length greater than 3 .” Bertrand derived three different ‘correct’ answers, the correctness depending on interpretation of the word, random. Here we employ geomet...
متن کاملThe long and the short of it: new insights on sperm length help demystify the complexities of sexual selection
H sperm are approximately 6000th of a centimeter long, a small fraction of a man’s total body length. By contrast, fruit fly (Drosophila spp.) sperm can reach nearly 6 cm, roughly twenty times the total length of their bodies. This dramatic variation in male reproductive biology is explored in a recent paper from the journal Nature.1 While the literature on sperm competition has for decades emp...
متن کاملParadox in the Poetry of Hazin-e Lahiji
Paradox is one of the literary techniques in the poetry of the Safavid poets. Hazin-e Lahiji, like so many other poets of that age, employed this technique in his pursuit and showed that "unfamiliar meaning". Paradox is used in the poetry of Hazin-e Lahiji for the purpose of defamiliarization and exoticism. The poet in order to create new implications and subtle and insightful points and also t...
