In 2006, In-Sink-Erator removed the hyphens from its name, becoming InSinkErator. It also redesigned the company logo and released a re-engineered line of high technology disposers branded as the Evolution Series. [citation needed] On November 1, 2022, InSinkErator was acquired by Whirlpool Corporation. [4] [5]
By expressing models in terms of the instantaneous rates of change we can avoid estimating a large numbers of parameters for each branch on a phylogenetic tree (or each comparison if the analysis involves many pairwise sequence comparisons). The models described on this page describe the evolution of a single site within a set of sequences.
In the United States, 50% of homes had disposal units as of 2009, [12] compared with only 6% in the United Kingdom [13] and 3% in Canada. [14]In Britain, Worcestershire County Council and Herefordshire Council started to subsidize the purchase of garbage disposal units in 2005, in order to reduce the amount of waste going to landfill and the carbon footprint of garbage runs.

Multiregional evolution holds that the human species first arose around two million years ago and subsequent human evolution has been within a single, continuous human species. This species encompasses all archaic human forms such as Homo erectus , Denisovans , and Neanderthals as well as modern forms, and evolved worldwide to the diverse ...
The court jester hypothesis builds upon the punctuated equilibrium theory of Stephen Gould (1972) [8] by providing a primary mechanism for it. [2] The 2001 paper by Barnosky that is one of the first to use the term appropriate for the Court Jester side of the debate: the Stability hypothesis of Stenseth and Maynard Smith (1984), Vrba's Habitat Theory (1992), Vrba's Turn-over pulse hypothesis ...
In biology, a substitution model, also called models of sequence evolution, are Markov models that describe changes over evolutionary time. These models describe evolutionary changes in macromolecules, such as DNA sequences or protein sequences, that can be represented as sequence of symbols (e.g., A, C, G, and T in the case of DNA or the 20 "standard" proteinogenic amino acids in the case of ...
