Today, all humans are classified as belonging to the species Homo sapiens and sub-species Homo sapiens sapiens. However, this is not the first species of homininae: the first species of genus Homo, Homo habilis, are theorized to have evolved in East Africa at least 2 million years ago, and members of this species populated different parts of Africa in a relatively short time. Homo erectus is theorized to have evolved more than 1.8 million years ago, and by 1.5 million years ago had spread throughout Europe and Asia. Virtually all physical anthropologists agree that Archaic Homo sapiens (A group including the possible species H. heidelbergensis, H. rhodesiensis and H. neanderthalensis) evolved out of African Homo erectus ((sensu lato) or Homo ergaster).

How many millions of years ago had Homo erectus spread throughout Europa and Asia?
Answer: 1.5

The current Mac product family uses Intel x86-64 processors. Apple introduced an emulator during the transition from PowerPC chips (called Rosetta), much as it did during the transition from Motorola 68000 architecture a decade earlier. The Macintosh is the only mainstream computer platform to have successfully transitioned to a new CPU architecture, and has done so twice. All current Mac models ship with at least 8 GB of RAM as standard other than the 1.4 GHz Mac Mini, MacBook Pro (without Retina Display), and MacBook Air. Current Mac computers use ATI Radeon or nVidia GeForce graphics cards as well as Intel graphics built into the main CPU. All current Macs (except for the MacBook Pro without Retina Display) do not ship with an optical media drive that includes a dual-function DVD/CD burner. Apple refers to this as a SuperDrive. Current Macs include two standard data transfer ports: USB and Thunderbolt (except for the MacBook (2015 version), which only has a USB-C port and headphone port). MacBook Pro, iMac, MacBook Air, and Mac Mini computers now also feature the "Thunderbolt" port, which Apple says can transfer data at speeds up to 10 gigabits per second. USB was introduced in the 1998 iMac G3 and is ubiquitous today, while FireWire is mainly reserved for high-performance devices such as hard drives or video cameras. Starting with the then-new iMac G5, released in October 2005, Apple started to include built-in iSight cameras on appropriate models, and a media center interface called Front Row that can be operated by an Apple Remote or keyboard for accessing media stored on the computer. Front Row has been discontinued as of 2011, however, and the Apple Remote is no longer bundled with new Macs.

What processors are used by the current Mac product family?
Answer: Intel x86-64

During the 20th century, many artists immigrated to Mexico City from different regions of Mexico, such as Leopoldo Mendez, an engraver from Veracruz, who supported the creation of the socialist Taller de la Grafica Popular (Popular Graphics Workshop), designed to help blue-collar workers find a venue to express their art. Other painters came from abroad, such as Catalan painter Remedios Varo and other Spanish and Jewish exiles. It was in the second half of the 20th century that the artistic movement began to drift apart from the Revolutionary theme. Jose Luis Cuevas opted for a modernist style in contrast to the muralist movement associated with social politics.

What was the Popular Graphics Workshop mission?
Answer:
help blue-collar workers find a venue to express their art
