funny-peculiar or funny ha-ha Most often heard interrogatively, this expression serves to distinguish between two meanings of the word funny—‘peculiar’ and ‘amusing or humorous.’ In 1938, I. Hay used this expression in a play entitled Housemaster. Since then, funny-peculiar or funny ha-ha has gained currency and is frequently heard today.

know a hawk from a handsaw See PERCEPTIVENESS.

know chalk from cheese See PERCEPTIVENESS.

make head or tail of To make sense of, to understand or decipher; also make heads or tails of. The head and the tail are opposite sides of a coin. Tossing a coin is a common method of deciding by chance; the outcome is determined by which side is up when the coin lands. It is easy to see how a coin landing in such a way that it cannot clearly be called either heads or tails gave rise to the frequently heard negative not make head nor tail of, implying confusion and senselessness.

Pray what is the design or plot? for I could make neither head nor tail on’t. (Henry Fielding, The Author’s Farce, 1729)

Those species, then, also will be 'simultaneous' point of nature, which, belonging to the same genus, are distinguished each from each by one and the same method of differentiation.
There is a strong argument in favour of the sharp differentiation of castes and of races (and even of sexes; see Note on Chapter XVIII.) running all through Nietzsche's writings.
`Seeing the ease and security in which these people were living, I felt that this close resemblance of the sexes was after all what one would expect; for the strength of a man and the softness of a woman, the institution of the family, and the differentiation of occupations are mere militant necessities of an age of physical force; where population is balanced and abundant, much childbearing becomes an evil rather than a blessing to the State; where violence comes but rarely and off-spring are secure, there is less necessity--indeed there is no necessity--for an efficient family, and the specialization of the sexes with reference to their children's needs disappears.
Such a man will study vibrations as Darwin studied the differentiation of species.

In these remarks we have referred to special parts or organs being still variable, because they have recently varied and thus come to differ; but we have also seen in the second Chapter that the same principle applies to the whole individual; for in a district where many species of any genus are found--that is, where there has been much former variation and differentiation, or where the manufactory of new specific forms has been actively at work--there, on an average, we now find most varieties or incipient species.
It is the differentiation to which all organisms grow.
There had been changes, differentiations brought about by diverse conditions and infusions of other blood; but down at the bottom of their beings, twisted into the fibres of them, was a heritage in common, a sameness in kind that time had not obliterated.
Knowledge of the genes that control this differentiation and the paths that cells take to their final, differentiated forms is an important biological question because dysregulation of this process is linked to pathologies --such as obesity, osteoporosis, cancer, tooth loss, and aging.
