primordial soup ...
historical radius of the spherical universe we can observe, is about 78 billion light years. we cannot observe anything outside that sphere, as information from it would have taken longer to reach us than the life of the universe ! the universe, which includes time, space, and everything in it, begins with the big bang 13.7 ± 0.2 billion years ago.
probably all of the organic beings which have ever lived on this earth have descended from some one primordial form, into which life was first breathed. the species we see today are but the smallest part of what blind destiny has produced, all living species of today are related to each other through common descent, products of evolution and speciation over billions of years.
human DNA sequences are approximately 6.6% divergent from those of their nearest genetic relative the baboons, 1.6% from gorillas , and 1.2% from chimpanzee, 0.1 % between you and me.

the brown hawk owl, ninox scutulata, is a resident breeder in tropical south asia. this species is a part of the larger grouping of owls known as typical owls, strigidae, which contains most species of owls, the other grouping are the barn owls, tytonidae.
it is a medium-sized (32cm) owl with a hawk-like shape due to its long tail and lack of a distinct facial disk. the eyes are large and yellow. sexes are similar. it lays three to five eggs in a tree hole. this species is very nocturnal. It feeds mainly on large insects, frogs, lizards, small birds, and mice. the call is a soft, musical koo-ook...koo-ook ...

flying frog ...
the origin of novel phenotypes has challenged evoluionary biologists since the time of darwin. darwin's theory of evolution provides an explanation for how natural selection eliminates the less fit phenotypes, but leaves open the question of how novel phenotypes arise !
rhacophorus malabaricus is a large-sized tree frog endemic to the western ghats of india. inhabits evergreen, and semi-evergreen forests and builds arboreal foam nests. gliding tree frogs have features such as enlarged, extensively webbed hands and feet with adhesive discs, skin flaps on elbows and ankles. these frogs use gliding to descend from the canopy down to mating sites over temporary pools on the rainforest floor and to escape from predators.
aerodynamic stability and maneuverability
the motion an animal experiences during flight is marked by transitory oscillations (phugoid mode, short-period mode, Dutch-roll mode and spiral mode) superimposed over translation along a flight path. In addition, the flight path may be changing as a result of postural changes by the animal.
maneuverability is the ability of a gliding animal to accelerate and change its flight path. a gliding animal is capable of accelerating linearly and rotationally. turning maneuvers are accomplished by rotations about the glider's center of mass that in turn alter the aerodynamic forces acting on the glider. maneuverability depends on the magnitude of the aerodynamic forces the frog can generate as well as the frog's aerodynamic stability.
this rotation can be resolved into rotations about three orthogonal axes, pitch, roll and yaw. the origin of the axes is fixed to the animal's center of mass, and the axes themselves are fixed to the animal; the axes translate and rotate as the animal translates and rotates. (A) rotation about the cranial-caudal axis is termed roll angle, rolling rotates the animal's right side up or down. (B) rotation about a dorso-ventral axis is termed yaw angle, yawing rotates the animal's snout to the left or right. (C) rotation about a lateral axis is termed angle of attack, pitching rotates the animal's snout up or down. grey arrows indicate the directions of the indicated torques.
tree frogs maneuvered in the tilted wind-tunnel using two different turning mechanisms: a banked turn (the frog rolls into the turn) and a crabbed turn (the frog yaws into the turn). the maneuverability was approximately one-third of the maneuverability of a falcon.
thank u so much for your wonderfull research MICHAEL G. McCAY

bufo camo ...
frogs and toads comprise the order anura. there are about 3,500 known species of frogs and 400 kinds of toads, still plenty being discovered every day. they are found on every continent except antarctica. they are very sensitive to climate change, thus called as an indicator species and their population is declining rapidly. the word "frog" can be used to describe all stout bodied amphibians, smooth and moist skinned, that have long hind limbs for leaping.

spider silk is tough, stronger (upto 5oo % ) than steel and more elastic (up to 300 %) than anything else we can make is surely a humble reminder of the fact that nature created us and not the other way around.

spot the elephant ...
many a times the obvious isn't that easy to spot, cos there is something even more obvious out there ... lets not forget that plants evolved here on earth some 100's of million years ago, before the first animal life happened and animals were designed as their couriers to spread their gene and diversity for which one get fed. enlarge the picture and u will really see an elephant ... somewhere in the big picture ...

a point is not part of a line ...
Here forms, here colours, here the character of every part of the universe are concentrated to a point; and that point is so marvellous a thing ... Oh! marvellous, O stupendous Necessity— by thy laws thou dost compel every effect to be the direct result of its cause, by the shortest path. These are miracles...
