Walking with Beasts: Walking with Beasts (Walking with Prehistoric Beasts in North American releases) is a 2001 six-part television documentary miniseries, produced by the BBC Natural History Unit.  It is the second installment of the Walking With... series and a sequel to "Walking with Dinosaurs".

Like "Dinosaurs", its narrative is presented in the style of a traditional nature documentary.  Some of the concepts it illustrates are the evolution of whales, horses, and humans.

Whisper number: Whisper numbers are the "unofficial and unpublished earnings per share (EPS) forecasts that circulate among professionals on Wall Street... generally reserved for the favored (wealthy) clients of a brokerage."  According to Per Afrell, a former analyst at UBS Warburg, buy and sell side research analysts generally maintain a 20 plus page spreadsheet to calculate their earnings per share estimates.  When the estimate is first calculated by sell-side analysts, the number is submitted to companies such as First Call to be averaged with other analysts’ estimates for the consensus earnings estimate.  As new information is made available and plugged into the spreadsheet, the calculation may change several times leading up to a company’s actual earnings release.  However, the analyst is generally not going to issue a new report and revise his or her published estimate with each new calculation, resulting in the analyst’s true expectations differing from his or her published number.  Therefore, when someone within the firm, an institutional client, or even a retail client asks the analyst his or her expectation for the company, the response is often different from the published estimate.  This number then gets passed among trading desks and professional traders as the whisper number.

First Call vehicle: The First Call vehicle is a vehicle used in the funeral service industry.  This type of vehicle is used to pick up the remains of a recently deceased person, and transport that person to the funeral home for preparation.  This initial pickup is called the "first call", hence the name of these vehicles.  While some funeral homes will use the hearse for these initial pickups, having vehicles for first calls and using the hearse solely for funerals reduces wear on hearses and makes the first call process more discreet.

Iqama: The word iqama (Arabic: إقامة‎ ‎ ) or ikamet (Turkish transliteration) refers to the second call to Islamic Prayer, given immediately before the prayer begins.  Generally, the iqama is given more quickly and in a more monotonous fashion, compared to the adhan, as it is addressed to those already in the mosque rather than a reminder for those outside it to come to the mosque.  Aside from a difference in the number of repetitions of each formulæ, the iqama differs from the first call to prayer, the adhan, in only one place (line 6, below):
