An open textbook, likely in Bulgarian, is displayed at an angle, resting on an indistinct surface. The right page features a prominent color photograph of two lions. One lion is a distinctive light, almost white, color, while the other is a more common golden-tan. Both are lying down, looking upwards, next to what appears to be a shallow pool of water or a reflective surface. A small red square with the number '1' is located in the bottom right corner of this image. The left page of the textbook contains extensive text in Cyrillic script, along with smaller illustrations. Key headings visible include "Макроеволюция" (Macroevolution) and "Вид и видообразуване" (Species and Speciation). Sections discuss "Критерии за определяне на видовата принадлежност" (Criteria for determining species affiliation), referencing "Морфологичен критерий" (Morphological criterion) and "Физиологичен" (Physiological). The text mentions historical figures such as "Дарвин" (Darwin) and "Ламарк" (Lamarck). A partial portrait of a person in a dark, historical-style painting is labeled "Джон Рей (1813 – 1893)" (John Ray/Rae). At the top left, small diagrams depict concepts, including an animal silhouette and labeled terms like "цистеини" (cysteines) and "пирувам" (pyruvate), suggesting content related to genetics or biochemistry. The book has white pages with black text, highlighted with orange and red headings. The scene gives the impression of a textbook open during a study session.
