A dragonfly in its final moult, undergoing metamorphosis, it begins transforming from its nymph form to an adult. Metamorphosis is a biological process by which an animal physically develops including birth transformation or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation.

Metamorphoses (Transformations) is a Latin narrative poem by the Roman poet Ovid, considered his magnum opus.Comprising fifteen books and over 250 myths, the poem chronicles the history of the world from its creation to the deification of Julius Caesar within a loose mythico-historical framework.
Other works include Boios's Ornithogonia (which included tales of humans becoming birds) and little-known Antoninus Liberalis's own Metamorphoses, which drew heavily from Nicander and Boios. [ 13 ] Below is a list of permanent and involuntary transformations featured in Greek and Roman mythological corpus.
Human embryonic development refers to the development and formation of the human embryo. It is characterised by the process of cell division and cellular differentiation of the embryo that occurs during the early stages of development. In biological terms, human development entails growth from a one-celled zygote to an adult human being.
It is a stone which has in it branches like those of a tree. After mineral life evolves vegetation. The evolution of vegetation culminates with a tree which bears the qualities of an animal. This is the date-palm. It has male and female genders. It does not wither if all its branches are chopped but it dies when the head is cut off.
Neoteny in humans is the slowing or delaying of body development, compared to non-human primates, resulting in features such as a large head, a flat face, and relatively short arms. These neotenic changes may have been brought about by sexual selection in human evolution. In turn, they may have permitted the development of human capacities such ...
The global challenge we should be talking more about.
Orthologous receptors exist in humans providing, the authors propose, evidence for a mechanism of human pheromone detection. [69] Although there are disputes about the mechanisms by which pheromones function, there is evidence that pheromones do affect humans. [70]
