late 20th and early 21st century critics, Jonathan Wells and Stephen Jay Gould, have objected to the continued use of Haeckel ’ s embryo drawings in textbooks.

On the other hand, Michael K. Richardson, Professor of Evolutionary Developmental Zoology, Leiden University, while recognizing that some criticisms of the drawings are legitimate ( indeed, it was he and his co-workers who began the modern criticisms in 1998 ), has supported the drawings as teaching aids, and has said that " on a fundamental level, Haeckel was correct "

Romanes ' 1892 copy of Ernst Haeckel's allegedly fraudulent embryo drawings ( this version of the figure is often attributed incorrectly to Haeckel ).

Haeckel ’ s embryo drawings are primarily intended to express his idiosyncratic theory of embryonic development, the Biogenetic Law, which in turn assumes ( but is not crucial to ) the evolutionary concept of common descent.

In addressing his embryo drawings to a general audience, Haeckel does not cite any sources, which gives his opponents the freedom to make assumptions regarding the originality of his work.

Haeckel was not the only one to create a series of drawings representing embryonic development.

Although Rutimeyer did not denounce Haeckel ’ s embryo drawings as fraud, he argued that such drawings are manipulations of public and scientific thought.

Nevertheless, Bischoff ’ s main argument was in reference to Haeckel ’ s drawings of human embryos, for Haeckel is later accused of miscopying the dog embryo from him.

Throughout Haeckel ’ s time, criticism of his embryo drawings was often due in part to his critics ' belief in his representations of embryological development as “ crude schemata .” In this way, Haeckel specifically selected relevant features to portray in his drawings.

In 1877, Rudolf Virchow ( 1821 – 1902 ), once an inspiration to Haeckel at Würzburg, proclaimed that Haeckel ’ s embryo drawings represent mere hypotheses.

Michael Richardson and his colleagues in a July 1997 issue of Anatomy and Embryology, demonstrated that Haeckel fudged his drawings in order to exaggerate the similarity of the phylotypic stage.

In a March 2000 issue of Natural History, Stephen Jay Gould argued that Haeckel “ exaggerated the similarities by idealizations and omissions .” As well, Gould argued that Haeckel ’ s drawings are simply inaccurate and falsified.

Some version of Haeckel ’ s drawings can be found in many modern biology textbooks in discussions of the history of embryology, with clarification that these are no longer considered valid.

Haeckel produced several embryo drawings that often overemphasized similarities between embryos of related species.

" Moreover, " vertebrate embryos, for most of the longest period of middevelopment, do look remarkably alike, pretty much, but not exactly, as Haeckel figured them in some of his drawings "( emphasis in original ).

A stone bridge of 17 arches was certainly constructed in 1685 and this was detailed in profile drawings by Thomas Rhodes in 1833.

It was said that his drawings of stones, window traceries, arches and ornamentation were so precise that stonemasons could execute his intentions from one single drawing.

There have been thousands of drawings ( mostly in comics, some elsewhere ) of combat frogmen and other scuba divers with two-cylinder twin-hose aqualungs shown wrongly with one wide breathing tube coming straight out of each cylinder top with no regulator, far more than of twin-hose aqualungs drawn correctly with a regulator, or of combat frogmen with rebreathers.

The original engineering drawings label the barrel as " tube ", the trigger as " yoke ", the firing pin as " control rod ", and the trigger guard as " spanner ".

Von Baer ’ s embryo drawings display that individual development proceeds from general features of the developing embryo in early stages through differentiation into special features specific to the species, establishing that linear evolution could not occur.

Named features on bodies so small that coordinates have not yet been determined are identified on drawings of the body that are included in the IAU Transactions volume of the year when the names were adopted.

Satellite rings and gaps in the rings are named for scientists who have studied these features ; drawings that show these names are also included in the pertinent Transactions volume.

His book A Natural History of Australia ( Academic Press, 1998 ) features 200 of his color photographs, 220 line drawings and maps, and over 500 references.

Agnes Mongan has written of the portrait drawings: Before his departure in the fall of 1806 from Paris for Rome, the familiar characteristics of his drawing style were well established, the delicate yet firm contour, the definite yet discreet distortions of form, the almost uncanny capacity to seize a likeness in the precise yet lively delineation of features. The preferred materials were also already established: the sharply pointed graphite pencil on a smooth white paper.

Previously, the dimensions of the French Blue had been known only from two drawings made in 1749 and 1789 ; although the model slightly differs from the drawings in some details, these details are identical to features of the Hope Diamond, allowing CAD technology to digitally reconstruct the French Blue around the recut stone.
