还 There is no exception to the rule that every organic being naturally increases at so high a rate, that if not destroyed, the earth would soon be covered by the progeny of a single pair. Even slow-breeding man has doubled in twenty-five years, and at this rate, in a few thousand years, there would literally not be standing room for his progeny. Linnaeus has calculated that if an annual plant produced only two seeds and there is no plant so unproductive as this and their seedlings next year produced two, and so on, then in twenty years there would be a million plants. The elephant is reckoned to be the slowest breeder of all known animals, and I have taken some pains to estimate its probable minimum rate of natural increase: it will be under the mark to assume that it breeds when thirty years old, and goes on breeding till ninety years old, bringing forth three pairs of young in this interval; if this be so, at the end of the fifth century there would be alive fifteen million elephants, descended from the first pair.
On Sundays, Miss Pross dined at the Doctor's table, but on other days persisted in taking her meals at unknown periods, either in the lower regions, or in her own room on the second floor--a blue chamber, to which no one but her Ladybird ever gained admittance. On this occasion, Miss Pross, responding to Ladybird's pleasant face and pleasant efforts to please her, unbent exceedingly; so the dinner was very pleasant, too.
There are many laws regulating variation, some few of which can be dimly seen, and will be hereafter briefly mentioned. I will here only allude to what may be called correlation of growth. Any change in the embryo or larva will almost certainly entail changes in the mature animal. In monstrosities, the correlations between quite distinct parts are very curious; and many instances are given in Isidore Geoffroy St Hilaire's great work on this subject. Breeders believe that long limbs are almost always accompanied by an elongated head. Some instances of correlation are quite whimsical; thus cats with blue eyes are invariably deaf; colour and constitutional peculiarities go together, of which many remarkable cases could be given amongst animals and plants. From the facts collected by Heusinger, it appears that white sheep and pigs are differently affected from coloured individuals by certain vegetable poisons. Hairless dogs have imperfect teeth; long-haired and coarse-haired animals are apt to have, as is asserted, long or many horns; pigeons with feathered feet have skin between their outer toes; pigeons with short beaks have small feet, and those with long beaks large feet. Hence, if man goes on selecting, and thus augmenting, any peculiarity, he will almost certainly unconsciously modify other parts of the structure, owing to the mysterious laws of the correlation of growth.The result of the various, quite unknown, or dimly seen laws of variation is infinitely complex and diversified. It is well worth while carefully to study the several treatises published on some of our old cultivated plants, as on the hyacinth, potato, even the dahlia, &c.; and it is really surprising to note the endless points in structure and constitution in which the varieties and sub varieties differ slightly from each other. The whole organization seems to have become plastic, and tends to depart in some small degree from that of the parental type.

2、 If thou doest earnestly love faire Sophronia, who is betroathedand afflanced to me, it is no matter for me to marvaile at: but Ishould rather be much abashed, if thou couldst not intyrely affecther, knowing how beautifull she is, and the nobility of her minde,being as able to sustaine passion, as the thing pleasing is fullest ofexcellence. And looke how reasonable thou fanciest Sophronia, asunjustly thou complainest of thy fortune, in ordaining her to be mywife, although thou doest not speake it expresly: as being of opinion,that thou mightst with more honesty love her, if she were anyothers, then mine. But if thou art so wise, as I have alwayes heldthee to be, tell me truely upon thy faith, to whom could Fortunebetter guide her, and for which thou oughtest to be more thankfull,then in bestowing her on me? Any other that had enjoyed her,although thy love were never so honest, yet he would better affect herhimselfe, then for thee, which thou canst not (in like manner) lookefor from me, if thou doest account me for thy friend, and asconstant now as ever.
"'My dear nurse," said Penelope, "do not exult too confidentlyover all this. You know how delighted every one would be to seeUlysses come home- more particularly myself, and the son who hasbeen born to both of us; but what you tell me cannot be really true.It is some god who is angry with the suitors for their greatwickedness, and has made an end of them; for they respected no manin the whole world, neither rich nor poor, who came near them, whocame near them, and they have come to a bad end in consequence oftheir iniquity. Ulysses is dead far away from the Achaean land; hewill never return home again."[回复]
Climate plays an important part in determining the average numbers of a species, and periodical seasons of extreme cold or drought, I believe to be the most effective of all checks. I estimated that the winter of 1854-55 destroyed four-fifths of the birds in my own grounds; and this is a tremendous destruction, when we remember that ten per cent. is an extraordinarily severe mortality from epidemics with man. The action of climate seems at first sight to be quite independent of the struggle for existence; but in so far as climate chiefly acts in reducing food, it brings on the most severe struggle between the individuals, whether of the same or of distinct species, which subsist on the same kind of food. Even when climate, for instance extreme cold, acts directly, it will be the least vigorous, or those which have got least food through the advancing winter, which will suffer most. When we travel from south to north, or from a damp region to a dry, we invariably see some species gradually getting rarer and rarer, and finally disappearing; and the change of climate being conspicuous, we are tempted to attribute the whole effect to its direct action. But this is a very false view: we forget that each species, even where it most abounds, is constantly suffering enormous destruction at some period of its life, from enemies or from competitors for the same place and food; and if these enemies or competitors be in the least degree favoured by any slight change of climate, they will increase in numbers, and, as each area is already fully stocked with inhabitants, the other species will decrease. When we travel southward and see a species decreasing in numbers, we may feel sure that the cause lies quite as much in other species being favoured, as in this one being hurt. So it is when we travel northward, but in a somewhat lesser degree, for the number of species of all kinds, and therefore of competitors, decreases northwards; hence in going northward, or in ascending a mountain, we far oftener meet with stunted forms, due to the directly injurious action of climate, than we do in proceeding southwards or in descending a mountain. When we reach the Arctic regions, or snow-capped summits, or absolute deserts, the struggle for life is almost exclusively with the elements.That climate acts in main part indirectly by favouring other species, we may clearly see in the prodigious number of plants in our gardens which can perfectly well endure our climate, but which never become naturalised, for they cannot compete with our native plants, nor resist destruction by our native animals.[回复]

Goldie Blox是一家玩具公司，使命是重新定义玩具商店中的“粉红走道”。在科学、技术、工程和数学（STEM）教育和职业领域，男性数量要大大多于女性，大部分女孩往往在八岁前就对这些领域失去了兴趣。Goldie Blox所设计的玩具则通过吸引女孩发展强大的口头及故事讲述能力的方式——同时仍提供机会来发展日后可转化成对工程学兴趣的技能——来鼓励和启发未来的工程师们。说到机会，一家玩具初创企业如何能在和一开始就统治着玩具行业的大公司的抗衡中脱颖而出呢？Goldie Blox走出了明智的一步：最近，该公司发布了一段视频，采用了Beastie Boys的歌曲《女孩们》（Girls）做背景音乐，该视频得到了病毒式传播。尽管这段视频最终被撤下，但Goldie Blox在提高公众对让更多女性和女孩对STEM产生兴趣——以及对Goldie Blox玩具——的认知上，做了一份相当不错的工作。巴萨功勋宣布今夏离队
