The Insects: Structure and Function
Winglessness occurs as a primitive condition in the Apterygota, while the
ectoparasitic orders Phthiraptera and Siphonaptera are secondarily Wingless.
Wingless species are also widespread in most other orders, but apparently do
not occur in ...

Mountains and Man: A Study of Process and Environment
Winglessness and flighttessness. A corollary of smaller size in insects is a
tendency toward winglessness or reduced wing-size. This is a dominant
characteristic of high-altitude insects, observed in many mountain areas (
Darlington 1943; ...

The Historical Development of Diptera
Particularly characteristic for the phoromorphs is the widespread development of
winglessness in connection with the parasitic and symbiotic way of life; usually
the winglessness develops only in females. The phenomenon of winglessness ...

The Biology of Rarity: Causes and Consequences of ...
If, for example, a rare wingless species of beetle was a relatively recent offshoot
of a clade in which older and commoner species are also wingless, it would be
hard to argue that winglessness arose as an adaptation to the conditions of rarity.

Fat Chemistry: The Science Behind Obesity
Among this latter group is a strain homozygous for the recessive trait of
winglessness, and the heritability is absolute – in some environments. Weather
affects the gene use by 100%. Normally, the progeny of the wingless parents
follow their ...

Genetics and Evolution of the Domestic Fowl
7.3h Wingless Two forms of winglessness have been described, an autosomal
recessive (wg) (Hutt, 1949) and a sex-linked recessive (wl) (Pease, 1962;
Lancaster, 1968). Most embryos from both types of winglessness are
characterised by ...

Animal Migration, Orientation and Navigation
In general organisms can choose to breed “now” or "later" either "here" or in “
near” and / or “far” environments. Immediate breeding in the current habitat
requires no migration and often leads to strategies such as winglessness, ...

Metaphysics and Method in Plato's Statesman
Subsequent divisions singling out features of footedness, winglessness,
hornlessness, and so forth (276A4–5) should be retained.9 With the help of this
revised line of division, the major error (275A1) of mistaking the divine rule of
Cronus for ...

Ecology and Behaviour of the Ladybird Beetles (Coccinellidae)
In this species, winglessness is controlled by a single recessive allele, although
the extent of its development is determined by genetic background, modifier
genes and environmental influences, notably temperature (Marples et al. 1993 ,
Ueno ...

The Greatest Show on Earth: The Evidence for Evolution
There is an additional reason for winglessness in this riff-raff of lurkers and
squatters in ants' and termites' nests. Many of them (not the Phorid flies) have
over evolutionary time assumed a protective resemblance to ants, either (or both)
to fool ...
