Biology Professor Refuses to Recommend Students Who Don't Believe in Evolution

Before you ask me to write you a letter of recommendation for graduate or professional school in the biomedical sciences, there are several criteria that must be met. The request for a letter is best made by making an appointment to discuss the matter with me after considering these three criteria:

You should have earned an "A" from me in at least one semester that you were taught by me.

I should know you fairly well. Merely earning an "A" in a lower-division class that enrolls 500 students does not guarantee that I know you. In such a situation, all I would be able to provide is a very generic letter that would not be of much help in getting you into the school of your choice. You should allow me to become better acquainted with you. This can be done in several ways:

1) by meeting with me regularly during my office hours to discuss biological questions. 2) by enrolling in an Honors’ section taught by me. 3) by enrolling in my section of BIOL 4301 and serving as an undergraduate TA (enrollment is by invitation only). 4) by serving as the chairman or secretary of the Biology Advisory Committee.

If you set up an appointment to discuss the writing of a letter of recommendation, I will ask you: "How do you think the human species originated?" If you cannot truthfully and forthrightly affirm a scientific answer to this question, then you should not seek my recommendation for admittance to further education in the biomedical sciences.

Why do I ask this question? Let’s consider the situation of one wishing to enter medical school. Whereas medicine is historically rooted first in the practice of magic and later in religion, modern medicine is an endeavor that springs from the sciences, biology first among these. The central, unifying principle of biology is the theory of evolution, which includes both micro- and macro-evolution, and which extends to ALL species. How can someone who does not accept the most important theory in biology expect to properly practice in a field that is so heavily based on biology? It is hard to imagine how this can be so, but it is easy to imagine how physicians who ignore or neglect the Darwinian aspects of medicine or the evolutionary origin of humans can make bad clinical decisions. The current crisis in antibiotic resistance is the result of such decisions. For others, please read the citations below.

Good medicine, like good biology, is based on the collection and evaluation of physical evidence. So much physical evidence supports the evolution of humans from non-human ancestors that one can validly refer to the "fact" of human evolution, even if all of the details are not yet known. One can deny this evidence only at the risk of calling into question one’s understanding of science and of the method of science. Such an individual has committed malpractice regarding the method of science, for good scientists would never throw out data that do not conform to their expectations or beliefs. This is the situation of those who deny the evolution of humans; such a one is throwing out information because it seems to contradict his/her cherished beliefs. Can a physician ignore data that s/he does not like and remain a physician for long? No. If modern medicine is based on the method of science, then how can someone who denies the theory of evolution -- the very pinnacle of modern biological science -- ask to be recommended into a scientific profession by a professional scientist?

If you still want to make an appointment, you can do so in person during office hours (M-Th, 3:30-4:00), or by phoning my office at 742-2729, or by e-mailing me at michael.dini@ttacs.ttu.edu

It is NOT the case that there is lots of physical evidence for evolution. Not a single transitional fossil has ever been documented. Any taht have been put forth have been debunked as problematic or outright frauds.

You shouldn't lie like that. God looks harshly on those who bear false witness.

For a brief overview of transitional fossils (which you claim don't exist), see Transitional Vertebrate Fossils FAQ.

That's just a summary, check the journals and you'll find that new transitional fossils are being discovered literally on a daily basis.

Here's a taste -- it's the transitional fossils which have been found filling in the sequence between early Condylarths (the first hoofed mammals) and whales:

Cetaceans (whales, dolphins)

Just several years ago, there was still a large gap in the fossil record of the cetaceans. It was thought that they arose from land-dwelling mesonychids that gradually lost their hind legs and became aquatic. Evolutionary theory predicted that they must have gone through a stage where they had were partially aquatic but still had hind legs, but there were no known intermediate fossils. A flurry of recent discoveries from India & Pakistan (the shores of the ancient Tethys Sea) has pretty much filled this gap. There are still no known species-species transitions, and the "chain of genera" is not complete, but we now have a partial lineage, and sure enough, the new whale fossils have legs, exactly as predicted. (for discussions see Berta, 1994; Gingerich et al. 1990; Thewissen et al. 1994; Discover magazine, Jan. 1995; Gould 1994)

Eoconodon or similar triisodontine arctocyonids (early Paleocene) Unspecialized condylarths quite similar to the early oxyclaenid condylarths, but with strong canine teeth (showing first meat-eating tendencies), blunt crushing cheek teeth, and flattened claws instead of nails.
Microclaenodon (mid-Paleocene) -- A transitional genus intermediate between Eoconodon and the mesonychids, with molar teeth reorganizing in numerous ways to look like premolars. Adapted more toward carnivory.
Dissacus (mid-Paleocene) -- A mesonychid (rather unspecialized Paleocene meat-eating animal) with molars more like premolars & several other tooth changes. Still had 5 toes in the foot and a primitive plantigrade posture.
Hapalodectes or a very similar mesonychid (early Eocene, around 55 Ma) -- A small mesonychid with very narrow shearing molars, a distinctively shaped zygomatic arch, and peculiar vascularized areas between the molars. Probably a running animal that could swim by paddling its feet. Hapalodectes itself may be just too late to be the whale ancestor, but probably was a close relative of the whale ancestor. Says Carroll (1988): "The skulls of Eocene whales bear unmistakable resemblances to those of primitive terrestrial mammals of the early Cenozoic. Early [whale] genera retain a primitive tooth count with distinct incisors, canines, premolars,, and multirooted molar teeth. Although the snout is elongate, the skull shape resembles that of the mesonychids, especially Hapalodectes...."
Pakicetus (early-mid Eocene, 52 Ma) -- The oldest fossil whale known. Same skull features as Hapalodectes, still with a very terrestrial ear (tympanic membrane, no protection from pressure changes, no good underwater sound localization), and therefore clearly not a deep diver. Molars still have very mesonychid-like cusps, but other teeth are like those of later whales. Nostrils still at front of head (no blowhole). Whale- like skull crests and elongate jaws. Limbs unknown. Only about 2.5 m long. This skull was found with terrestrial fossils and may have been amphibious, like a hippo.
Ambulocetus natans (early-mid Eocene, 50 Ma) -- A recently discovered early whale, with enough of the limbs and vertebrae preserved to see how the early whales moved on land and in the water. This whale had four legs! Front legs were stubby. Back legs were short but well-developed, with enormous broad feet that stuck out behind like tail flukes. Had no true tail flukes, just a long simple tail. Size of a sea lion. Still had a long snout with no blowhole. Probably walked on land like a sea lion, and swam with a seal/otter method of steering with the front feet and propelling with the hind feet. So, just as predicted, these early whales were much like modern sea lions -- they could swim, but they could also still walk on land. (Thewissen et al., 1994)
Rodhocetus (mid-Eocene, 46 Ma) -- Another very recent (1993) fossil whale discovery. Had hind legs a third smaller than those of A. natans. Could probably still "waddle" a bit on land, but by now it had a powerful tail (indicated by massive tail vertebrae) and could probably stay out at sea for long periods of time. Nostrils had moved back a bit from the tip of the snout.
Basilosaurus isis, Protocetes, Indocetus ramani and similar small-legged whales of the mid-late Eocene (45-42 Ma) -- After Rodhocetus came several whales that still had hind legs, but couldn't walk on them any more. For example, B. isis (42 Ma) had hind feet with 3 toes and a tiny remnant of the 2nd toe (the big toe is totally missing). The legs were small and must have been useless for locomotion, but were specialized for swinging forward into a locked straddle position -- probably an aid to copulation for this long-bodied, serpentine whale. B. isis may have been a "cousin" to modern whales, not directly ancestral. Another recent discovery is Protocetes, a slightly more advanced whale from the late Eocene. It was about 3m long (dolphin sized), and still had primitive dentition, nostrils at end of snout, and a large pelvis attached to the spine; limbs unknown. Finally Indocetus is known from only fragmentary remains, but these include a tibia. These late Eocene legged whales still had mesonychid-like teeth, and in fact, some of the whale fossils were first mis-identified as mesonychids when only the teeth were found. ( See Gingerich et al. (1990) for more info on B. isis.)
Prozeuglodon (late Eocene, 40 Ma) Another recently discovered whale, found in 1989. Had almost lost the hind legs, but not quite: still carried a pair of vestigial 6- inch hind legs on its 15-foot body.
Eocetus, & similar "archeocete whales" of the late Eocene These more advanced whales have lost their hind legs entirely, but retain a"primitive whale" skull and teeth, with unfused nostrils. They grew to larger body size (up to 25m by the end of the Eocene), an had an elongate, streamlined body, flippers, and a cartilaginous tail fluke. The ear was modified for hearing underwater. Note that this stage of aquatic adaptation was attained about 15 million years after the first terrestrial mesonychids.
Dorudon intermedius -- a late Eocene whale probably ancestral to modern whales.

In the Oligocene, whales split into two lineages:

Toothed whales:

Agorophius (late Oligocene) -- Skull partly telescoped, but cheek teeth still rooted. Intermediate in many ways between archaeocetes and later toothed whales.
Prosqualodon (late Oligocene) -- Skull fully telescoped with nostrils on top (blowhole). Cheek teeth increased in number but still have old cusps. Probably ancestral to most later toothed whales (possibly excepting the sperm whales?)
Kentriodon (mid-Miocene) -- Skull telescoped, still symmetrical. Radiated in the late Miocene into the modern dolphins and small toothed whales with asymmetrical skulls.

Baleen (toothless) whales:

Aetiocetus (late Oligocene) -- The most primitive known mysticete whale and probably the stem group of all later baleen whales. Had developed mysticete-style loose jaw hinge and air sinus, but still had all its teeth. Later,
Mesocetus (mid-Miocene) lost its teeth.
Modern baleen whales first appeared in the late Miocene.

The professor is right. Anyone who doesn't know these things is way too ignorant to be given a passing grade in the biomedical sciences.
