But is this consistent with the rest of Holy Scripture? Six days you shall labor and do all your work. But the seventh day is the Sabbath of the Lord your God. You shall not do any work, you nor your son, nor your daughter, your manservant, nor your maidservant, nor your cattle, nor your stranger within your gates. For in six days the Lord made the heavens and the earth, the sea, and all that is in them, and rested the seventh day. Therefore the Lord blessed the Sabbath day, and sanctified it.
This obviously opposes any non-literal interpretation of Genesis 1, especially since this passage is the basis for our seven-day week—six days of work, followed by the seventh day of rest. We are not supposed to rest for millions of years, but for one day! The New Testament confirms the accuracy and authority of the Old Testament in all matters. Perhaps even mythical? He affirms their literal reading and verity, for example in Luke — In Mark —8 cf. Not only is this a reference to the literal event the creation of Adam and Eve described in Genesis , our Lord makes it clear that there were no long time-spans preceding Adam.
The first couple was there from the beginning , not billions of years later. Christ the Lord has thus put His stamp of affirmation on the literal, historical nature of these events. While rest never goes out of style, the role of the bed is evolving—and that means bedding must evolve with it. Shanahan said that, above all else, owners look for platform beds.
It requires less effort and maintenance while looking fresh and clean all the time. Owners are looking to the bed to lead the story of luxury. Appearance matters almost as much as comfort.

In all of and grabbed only at short range rather than pursued through these birds, there is a blind area behind the head. The width the water, may not allow the identification of prey items of this blind area differs between species, and it may extend before they are captured . Items are brought above the to above the head and even into the frontal hemisphere e.

It is worth lateral placement of the eyes. Put simply, more extensive noting that the visual field of herons is very similar to those visual coverage laterally would not be possible because of the tactile feeding ducks, such as mallards, but with the these ear structures would get in the way. Seeing what lies perpendicularly tive explanation that is associated with prey capture rather beneath the bill clearly has the advantage that a foraging than with nocturnal habit and enhanced visual sensitivity.
Because these directly into the binocular field, and directly into the flight prey have evolved rapid escape responses herons may get path of the bird.

On the other hand, such comprehensive the talons spread wide to fill the visual field in front of the coverage of the frontal hemisphere would appear not to have head, which is also the region where sound localization is an advantage for the majority of bird species which pursue most accurate.

It is not clear at what date the idea that a cycle, and some penguin species may forage at such depths link between nocturnality and broad binocularity arose, and that they regularly search for prey at the equivalent of it seems to be based upon casual observations of owls with night-time light levels . Furthermore, not all owls are noc- the assumption that the eyes of owls are frontally placed turnal hunters.

As noted above, at night. They roost and breed colonially in caves, is likely that this degree of binocular overlap is associated only emerging after dusk and flying within the forest with tool use .

So, the problem may not be as 7. The informational function of binocular vision great as it first appears, although lifetime exposure of the cornea and lens is potentially a major problem, but perhaps in birds most birds do not live long enough for the damaging effects That some bird species, such as woodcocks and mallards to accumulate. However, that some have sunshade devices have frontal binocular fields as narrow as and are still which help reduce the possibility that the sun is imaged on capable of taking off, flying and landing safely, in structurally the retina is clear .
In fact, a significant linear relationship complex habitats, supports the argument that extensive has been found between the size of the blind area above binocularity is not a prerequisite for the control of flight.
Fur- the head and eye size axial length of the eye . It has further been argued 8. Binocular vision, optic flow-fields and 9 that the function of binocular vision in birds does not lie in contralateral vision rstb. This latter argument has been presented in some detail object is the accurate identification of its position and, if , and it is not appropriate to rehearse all of the arguments there is relative speed between the object and the observer, here.
However, it is worth noting the following points: to gain information on time to contact. The actual distance of an object from a bird may be of little importance compared with knowing its direction and the time it may take to make — in birds and any other vertebrates with eyes placed later- contact with it. Such information is available from optic flow- ally in the skull binocular vision is, in fact, served by fields [88,89].
Furthermore, it has been shown that northern peripheral vision in each eye. This is quite unlike the situ- gannets Morus bassanus and hummingbirds Tochilidae Phil. B ation in animals with frontal eyes, such as humans where when carrying out manoeuvres that require accurate visual the central optics of each eye project forward and serve information regarding speed of approach to a target, the binocular region.
There is an important consequence appear to use flow-field information [90,91]. In mammals, of this use of the peripheral field of each eye to provide for- optic flow-field information is analysed in the accessory ward binocular vision; the question of corresponding optic system  and pretectum , and a similar accessory points. Neural pathways that could potentially link points system has been identified in birds [94,95]. This is because an image point in the far retinal associated with binocular portions of a visual field.
However, periphery of one eye will correspond with one that is more information on direction of travel towards a target and time centrally placed in the retina of the other eye . Further- to contact a target can be derived most efficiently when more, in bird species in which eye movements are present travel is directly towards a target. This will result in an optical they are non-conjugate with each eye able to make different flow-field which expands symmetrically about the image of rotations independently of the other, and it has also been the target.
This would seem to be the situation in the key shown that some bird species spontaneously abolished tasks described above.
For example, when pecking or lunging their binocular field, e. The essential consideration, however, is of the retina, and hence its projection through the optic that a flow-field which symmetrically expands about an nerve to higher centres, is not fixed; object directly ahead of the bird can only be achieved if the — the behaviours with which binocularity seems most clo- visual field of each eye extends contralaterally, i.
Thus, the important items would seem to require information that identifies consideration is contralateral vision, not binocular vision. Binocular vision is perhaps irrelevant in cant cognitive component especially with respect to food birds; what is important is contralateral vision. There is evidence It can be concluded that binocularity in birds functions to that such targets are identified primarily through lateral provide information on the direction of travel and time to rather than through frontal vision .

This ensures that each eye receives adaptations to quite specific perceptual demands. Reducing these to the single can be extracted.
