Leonard R. Brand : ウィキペディア英語版
Leonard R. Brand

Leonard Brand is a Seventh-day Adventist young earth creationist, biologist, paleontologist, and author. He is the chair professor of Loma Linda University Department of Earth and Biological Sciences.
As a Creationist, he teaches interventionism, a view of history that holds that there is intelligent intervention in history. His desire for respectful dialogue has been welcomed by advocates on both sides of the creation–evolution controversy. He challenges his fellow creationists to use caution when making scientific claims.
As a research scientist, his findings are published in various peer-reviewed journals. His most widely debated research was regarding fossil tracks at the Grand Canyon. He has a PhD in biology from Cornell University, received in 1970 when working for LLU La Sierra campus.
==Scientific research==

Brand began his scientific career in the study of small mammals. In 1968, Brand and Raymond Ryckman studied the systematics of deer mice (specifically the mainland cactus mouse and two related species isolated to nearby islands, the San Lorenzo and Angel Island mice. This was also the topic of Brand's masters. They confirmed the accepted taxonomy of these species, and showed that these species are still able to interbreed.〔
The research on deer mice is cited in sources including Mammal Species of the World (3rd ed. p.45). Also see: ;
; Review article ; the American Society of Mammalogists' species list; ; ; etc.〕
Starting in 1970, Brand reported on the tree nests and vocalisations of California chipmunks. This was also his PhD topic. Along with many other scientists, his reported methodologies and observations have added to the accumulating scientific knowledge of these mammals.〔

From 1999, the fossil remains of hundreds of whales (including the "Leviathan") were discovered as part of the Pisco formation in Peru. Brand and his associates studied the taphonomy of these well-articulated skeletons, and concluded that the burial of the whales in diatom sediment had been a very rapid event.
In 2000, Brand et al. have conducted field research on fossil turtles in the Bridger Formation of Wyoming. He has also been involved in taphonomy experiments using modern animal carcasses, particularly intended to aid understanding of the features of fossil turtles.
In the field of ichnology, Brand, along with Thu Tang, Andrew A. Snelling, and Steven Austin has proposed that fossil tracks in the Grand Canyon's Coconino Sandstone point to underwater deposition, rather than desert wind deposition of dry sand. 〔Comments on were published in: Science News, 141 (4):5, 1992; Geology Today, 8 (3):78–79, 1992; and Nature, 355:110, Jan 9, 1992. Brand responded to the comments: 〕 Brand and Tang studied western newts walking on sand under 4 cm of flowing water in an aquarium tank. By analogy, they concluded that at least part of the Coconino Sandstone was deposited under water. This hypothesis has been criticized by geologists who interpret evidence supporting sub-aerial formation.〔Lockley, M. G., and Hunt, A. P. (1995) ''Dinosaur Tracks and Other Fossil Footprints of the Western United States .'' New York, New York, Columbia University University Press, p. 338 ISBN 0-231-07926-5〕
Geologist Martin Lockley describes Brand's Salamander trackway study as "seriously flawed" and notes that Brand links the underwater tracks theory to the idea that the Grand Canyon was formed entirely by a catastrophic, biblical-style flood, a view which Lockley calls geologically naive and disingenuous. He criticizes Brand's book, ''Faith, Reason and Earth History'', for "leaving out any discussion of the objections published by geologists to his interpretation." Lockley praises Brand for admitting that creationists have made mistakes and that science-bashing can be counter-productive, for advocating respectful engagement, and for raising thought-provoking philosophical questions regarding evolution and sociobiology.〔

A number of studies have found evidence contradicting Brand and Tang's conclusions and Lockley and Hunt's 1995 book ''Dinosaur Tracks and Other Fossil Footprints of the Western United States'' suggests an alternative explanation with the tracks being made in air by extinct mammal-like reptiles called caseids. Inconsistencies that contradict the underwater hypothesis include:〔
*tracks demonstrating various running gaits impossible under water, at various angles to the slope;
*tracks made by many forms of invertebrates which would not leave prolific underwater tracks, including some which could only be made on completely dry sand; and
*raindrop impressions.
Apart from the controversy, his observations of underwater foot prints have been cited in peer-reviewed journals.〔 Brady (1939, 1947) and Sadler (1993) conducted neoichnological investigations with arthropods, but did not consider trackways produced subaqueously. Brand (1979, 1996) carried out extensive studies on trackways produced by modern amphibians and reptiles with different substrates, slope angles, and moisture contents, under both subaqueous and subaerial conditions. Different substrate conditions caused considerable variation in the appearance of trackways produced by one species. The trackways produced by uphill-walking salamanders on sloping dry sand in Brand’s (1979, fig. 6a, 6b) study are similar in their track depth and shape of pushback mounds to some uphill Palmichnium trackways found on foresets in the Muth Formation (Fig. 5B). Although the producers were different, these neoichnological studies provide an analogue for the mechanism of production of some of the Muth Palmichnium trackways.〕〔

In his report on laboratory controlled simulations of dinosaur footprints in sand, Simon J. Jackson cites eight scientists, including Brand. He says,
Brand has also been involved in research not published in mainstream scientific journals. In 1970 Berney Neufeld, Brand and Art Chadwick studied the controversial Paluxy tracks and, contrary to many creationists at that time, concluded that those tracks did not provide valid evidence for the coexistence of humans and dinosaurs.
