Some of the most precise correspondences involve transgender (particularly intersexuality) rather than homosexuality per se. Modern science has provided startling confirmation of a number of indigenous “beliefs” about purportedly cross-gendered animals, most notably the left-handed Bear figure of many Native American cultures. Biologists have actually uncovered evidence that some species of Bears probably are left-paw dominant. “Handedness,” or laterality, is a widespread phenomenon in the animal kingdom, with species as diverse as primates, cats, parrots, and even whales and dolphins showing preferences for the use of a right or left appendage (or side of the body) in various behaviors and tasks.44 Although in most species there is considerable variation between individuals as to which side is dominant, it does appear that at least some kinds of Bears are consistently “left-handed.” Scientists and naturalists report that Polar Bears, for example, regularly use their left paw for attack and defense as well as for clubbing seals and hauling them out of the water. In many cases they exhibit greater development of the left paw and may also use their left forelimb and shoulder to carry large objects. The consistency of left-paw use is exemplified by an incident in which wildlife biologists set up snare traps to capture and tag Polar Bears (for long-term study of their migrations). The traps were triggered by the bear’s reaching for some bait with its paw, and all 21 Bears caught in this way were snared by their left front foot.45 Incidentally, there also appears to be a correlation between left-handedness and homosexuality/transgender in humans: a higher than average proportion of gays and lesbians are left-handed (or ambidextrous), and one study found the percentage of left-handers among lesbians to be more than four times that among heterosexual women. Left-handedness also appears to be more common among transsexuals, particularly male-to-female transsexuals.46 As yet, no studies have looked for possible correlations between laterality and homosexuality/transgender in animals.
Another astonishing correspondence concerns the attraction of Bears to human menstrual blood, a widespread belief in many Native American tribes. Implausible as this connection may sound, zoologists decided to conduct experiments to see if there was any truth to these “superstitions.” Employing controlled olfactory- preference tests on Polar Bears in both laboratory and field settings, they found that the animals were indeed significantly more attracted to the odors in human menstrual blood than to a number of other smells, including several animal and food odors as well as nonmenstrual blood. In fact, human menstrual odors in many cases elicited a response from the Bears as strong as that prompted by the smell of seals (their primary food in the wild), which they could detect from more than 1,200 feet away.47
Even more extraordinary, biologists have found actual cases of physical gender-mixing in Bears. In 1986, Canadian zoologist Marc Cattet made a stunning discovery: the presence of significant numbers of “masculinized females” in wild populations of Grizzly, Black, and Polar Bears. These animals have the internal reproductive anatomy of a female combined with portions of the external genitalia of a male, including “penislike” organs. As many as 10–20 percent of the Bears in some populations may exhibit this phenomenon.48 Such individuals are able to reproduce, and most adult intersexual Bears are actually mothers that successfully raise cubs. In fact, the reproductive canal in some intersexual Bears extends through the phallus rather than forming a vagina, so that the female actually mates and gives birth through the tip of her “penis”—similar to the way female Spotted Hyenas mate and give birth through their “penile” clitoris. These findings offer striking parallels to the gender-mixing Bear Mother figure of many Native American tribes, as well as the Bimin-Kuskusmin and Inuit beliefs about “male mothers” and androgynous animals that give birth through a penis-clitoris.
Intersexual animals that combine male and female sex organs (and in some cases that are intermediate between males and females in their body proportions and size) also occur spontaneously in other mammals that are not usually hermaphroditic, such as primates (e.g., Common Chimpanzees, Rhesus Macaques, Savanna Baboons), whales and dolphins (e.g., Bowhead and Beluga Whales, Striped Dolphins), marsupials (e.g., Eastern Gray and Red Kangaroos, various Wallabies, Tasmanian Devils), and rodents and insectivores (e.g., moles).49 In fact, a veritable profusion of different kinds of gender mixing has been uncovered throughout the animal world—so much so that scientists have had to develop a special terminology to refer to the bewildering variety of intersexualities.

Other examples of the correspondences between indigenous views about transgendered animals and scientific observations can be found. Sambia (and other New Guinean) beliefs about all-female offspring, gender mixing, and sex change in marsupials and other animals may seem far-fetched, yet recent discoveries by zoologists studying a variety of species bear remarkable similarities to these ideas. For example, geneticists recently determined that significant numbers of female wood lemmings are actually chromosomally male (having an XY pattern). Moreover, some of these animals only give birth to female offspring, so that the population consists of 80 percent females. Similar phenomena occur in at least 7 other species of rodents, and individual females that only produce female offspring have also been reported as a recurring phenomenon in at least 12 different species of butterflies.53 True transsexuality is most often found in fishes (and “lower” animals), where the combination of sex change with chronological color change in some coral reef species echoes Sambia beliefs about sequential sex and plumage changes in birds (and other creatures). Cases of chromosomal “sex reversal” (males that have a female chromosomal pattern, or vice versa) occasionally occur in mammals such as moles, mole-voles,
