Continuous breeders

Continuous breeders are animal species that can breed or mate thought the year. This includes humans, who can have a child whenever they feel the time is right. In continuous breeders, females are sexually receptive during estrus, at which time ovarian follicles are maturing and ovulation can occur. Evidence of ovulation, the phase during which conception is most probable, is advertised to males among many non-human primates via swelling and redness of the genitalia.

In the 1960s, Ivan Goodbody researched three species of tropical ascidian and two species of crustacean, including the Puerto Rican sand crab, in Jamaica and determined them to be continuous breeders.

Continuous function

In mathematics, a continuous function is, roughly speaking, a function for which sufficiently small changes in the input result in arbitrarily small changes in the output. Otherwise, a function is said to be a discontinuous function. A continuous function with a continuous inverse function is called a homeomorphism.

Continuity of functions is one of the core concepts of topology, which is treated in full generality below. The introductory portion of this article focuses on the special case where the inputs and outputs of functions are real numbers. In addition, this article discusses the definition for the more general case of functions between two metric spaces. In order theory, especially in domain theory, one considers a notion of continuity known as Scott continuity. Other forms of continuity do exist but they are not discussed in this article.

As an example, consider the function h(t), which describes the height of a growing flower at time t. This function is continuous. By contrast, if M(t) denotes the amount of money in a bank account at time t, then the function jumps whenever money is deposited or withdrawn, so the function M(t) is discontinuous.

The Breeders

The Breeders are an American alternative rock band formed in 1990 by Kim Deal of the Pixies and Tanya Donelly of Throwing Muses. The band has experienced a number of lineup changes; Kim Deal has been the band's sole continual member. Their first album, Pod (1990), though not commercially successful, received wide critical acclaim. The Breeders' most successful album, Last Splash (1993), is best known for the hit single "Cannonball".

History

Formation

The Breeders' history began when Kim Deal, then bassist of the Pixies, began writing new material while the Pixies were touring Surfer Rosa in Europe with Throwing Muses. As neither band had plans in the immediate future, Deal discussed possible side projects with Throwing Muses guitarist Tanya Donelly. They recruited Carrie Bradley, violinist and vocalist in Boston band Ed's Redeeming Qualities, and recorded a short demo tape. Tracks on the demo tape included early versions of "Lime House", "Doe" and "Only in 3's".

With the help of three different drummers; David Narcizo, Mickey Bones, Carl Haarer and bassist Ray Halliday, Kim and Tanya completed their demo tape and subsequently played one show at The Rathskeller in Boston. They were not called the Breeders at this point, but were billed as "Boston Girl Super-Group". The band sent the tape to the English independent record label 4AD because both the Pixies and Throwing Muses were signed to the label. Upon hearing the tape, 4AD head Ivo Watts-Russell remarked "This is absolutely magical, beautiful stuff."
