Net als wrijfdeeg wordt roerdeeg met een spuitzak gespoten en drijven ze in de oven sterk uit. Dat komt door de speciale samenstelling van het deeg: ze bevatten veel vetstof en suiker. Roerdeeg wordt gebruikt voor het bakken van koekjes die door het sterke uitvloeien, plat, dun en krokant worden. Roerdeeg kan zowel met de hand als met een machine worden gemaakt.
Voor de handmatige bewerking worden een bekken en een spatel gebruikt.

There are many theories that attempt to explain why humans are bipedal, but none is wholly satisfactory. Increased speed can be ruled out immediately because humans are not very fast runners. Because bipedalism leaves the hands free, some scientists, including Darwin , linked it to tool use, especially tools for defense and hunting —i. This theory is problematic in that the earliest stone artifacts date only to about 3. Twentieth-century theories proposed a wide array of other factors that might have driven the evolution of hominin bipedalism: carrying objects, wading to forage aquatic foods and to avoid shoreline predators, vigilantly standing in tall grass, presenting phallic or other sexual display, following migrant herds on the savanna , and conserving energy bipedalism expends less energy than quadrupedism.
Furthermore, if the early bipeds were regularly exposed to direct midday tropical sunlight , they would benefit from standing upright in two ways: less body surface would be exposed to damaging solar rays , and they would find relief in the cooler air above the ground. Some scientists assume that the pre-bipedal primates were terrestrial quadrupeds, perhaps even knuckle-walkers like modern-day chimpanzees , bonobos , and gorillas.
Conversely, it is also possible that the first habitual walkers were already well prepared for terrestrial bipedality, having adaptations for running bipedally among branches and boughs, standing upright to forage overhead, and climbing vertical tree trunks and vines. This scenario is suggested by studies of gibbons , which routinely engage in these arboreal activities and virtually never elect to move on the forest floor but, if forced to the ground, run bipedally.
Gibbons have relatively long, powerful lower limbs, the same number of lumbar vertebrae that humans have great ape s have fewer , and chests of humanoid configuration. When walking on the ground, gibbons stand up straighter than chimpanzees, which are occasionally bipedal. Moreover, they exert less energy running on the ground than when running bipedally along branches or climbing vertically. Adopting a bipedal stance with full extension of the lower limbs thus would not have been a major challenge, since all apes have this capacity, though there would have been some alteration of the lower limb bones, joints, and ligaments.

Further discoveries by Louis and Mary Leakey in East Africa cemented Africa of hominins in East and South Africa dating from the early- to mid-Pleistocene Map showing the fossil sites of the earliest hominids. It is generally thought that by mya, there were at least two species of Homo in East Africa, Homo habilis.
Homo erectus. Most paleoanthropologists refer to them as Homo erectus literally “upright human”. However, a few researchers split them into two species– Homo ergaster literally “working human” and Homo erectus. The ergaster fossils were presumably somewhat earlier and have been found for the most part in Africa. The erectus discoveries have been found widespread in Africa, Asia, and Europe. In this tutorial, ergaster and erectus will be considered one species — Homo erectus.
Homo erectus were very successful in creating cultural technologies that allowed them to adapt to new environmental opportunities. They were true pioneers in developing human culture and in expanding their geographic range beyond Africa to populate tropical and subtropical zones elsewhere in the Old World. This territorial expansion most likely began around 1.
Toucan and hornbill beaks : a comparative study. The structure and mechanical behavior of Toco Toucan Ramphastos toco and Wreathed Hornbill Rhyticeros undulatus beaks were compared. The beak of both species is a sandwich-structured composite, having an exterior, or rhamphotheca, consisting of multiple layers of keratin scales and a core composed of a fibrous network of bony closed-cell foam.
The rhamphotheca is an arrangement of approximately 50microm diameter, overlapping, keratin tiles.
