A baseball bat is divided into several regions. The "barrel" is the thick part of the bat, where it is meant to hit the ball. The part of the barrel best for hitting the ball, according to construction and swinging style, is often called the " sweet spot." The end of the barrel is called the "top," "end," or "cap" of the bat.
The implication that bats are diphyletic has been fiercely disputed by many zoologists, not only based on the unlikelihood that wings would have evolved twice in mammals, but also on biochemical studies of molecular evolution, which indicate that bats are monophyletic. [13] [14] However, other studies have disputed the validity of these ...
Through adaptive evolution these structures in bats have undergone many morphological changes, such as webbed digits, elongation of the forelimb, and reduction in bone thickness. [1] Recently, there have been comparative studies of mouse and bat forelimb development to understand the genetic basis of morphological evolution.
The two oldest-known fossil skeletons of bats, unearthed in southwestern Wyoming and dating to at least 52 million years ago, are providing insight into the early evolution of these flying mammals ...
An Egyptian fruit bat (Rousettus aegyptiacus) carrying a fig. Fruit eating, or frugivory, is found in both major suborders. Bats prefer ripe fruit, pulling it off the trees with their teeth. They fly back to their roosts to eat the fruit, sucking out the juice and spitting the seeds and pulp out onto the ground.
The question of the origins of baseball has been the subject of debate and controversy for more than a century. Baseball and the other modern bat, ball, and running games – stoolball, cricket and rounders – were developed from folk games in early Britain, Ireland, and Continental Europe (such as France and Germany).
The leading theory of the evolution of megabats has been determined primarily by genetic data, as the fossil record for this family is the most fragmented of all bats. They likely evolved in Australasia , with the common ancestor of all living pteropodids existing approximately 31 million years ago.
The history of baseball can be broken down into various aspects: by era, by locale, by organizational-type, game evolution, as well as by political and cultural influence. The game evolved from older bat-and-ball games already being played in England by the mid-18th century. This game was brought by immigrants to North America, where the modern ...
