If, say, hand shape could not change independently of foot shape, selection could not make back feet suitable for walking while leaving the ape with usable hands.So for Darwin to think that natural selection explains major evolutionary innovations, he had to bet on the amount and kind of variation that typically exists in lineages.
The researchers were able to see signs of watery adaptation not seen in other dinosaurs: a small nostril located far back on the head, apparently to limit water intake; relatively long forelimbs; big flat feet suitable for paddling as well as walking on muddy ground; and very dense limb bones, which would have allowed Spinosaurus to submerge itself rather than float at the surface.
The canal was conceived as a broad canal, designed with locks which were 80 feet by 14 feet suitable for broad-beam barges.
A 20,000-square-foot warehouse, suitable for converting into studios and living space, sold for $230,000.
In fact the list of small- screen wonders that failed to blossom into healthy 35-foot versions suitable for the movie house is long enough to program a network.
It was to have a 12,000-square-foot rink — suitable for dancing, skating, curling, hockey and similar pursuits — in an elegant building modeled after the Palais de Glace in Paris.
From the western terminus to SR-200, the shoulder is up to 4 feet wide, suitable for bicycling, however the remainder of the route has much narrower shoulders, between less than or equal to wide.
The study objectives were to develop and validate two novel instruments for self-reported knee malalignment and foot rotation suitable for use in questionnaire studies of knee pain and osteoarthritis.
The surrounding environment was ascertained by asking, "Are parks or foot paths suitable for exercise or walking within 1 km from your home?" and "Are locations difficult for walking, such as hills or steps, within 1 km from your home?" with possible answers of "many," "some," "few," and "none".
However, no significant association was observed between the incidence of falls and annual equivalent income, frequency of outings, and availability of parks or foot paths suitable for exercise or walking after adding all covariates in the logistic regression model (Table 3).
