The origin of animals has always fascinated biologists. Studies on choanoflagellates, the closest living relatives of animals, have contributed major insights. The discovery of a multicellular choanoflagellate with light-regulated collective behaviour now provides a new perspective.

Changes in Homeotic (Hox) gene regulation have long been thought to drive the evolution of animal body plans. Direct genetic evidence of their evolutionary role has, however, remained limited. A new s...
Research on the evolution of cognition has long centered on vertebrates. Current research indicates that both complex social behavior and ecology influence the evolution of vertebrate cognition. Insec...
The evolution of nervous systems in animals has always fascinated biologists, and thus multiple evolutionary scenarios have been proposed to explain the appearance of neurons and complex neuronal cent...
The earliest unambiguous evidence for animals is represented by various trace fossils in the latest Ediacaran Period (550-541 Ma), suggesting that the earliest animals lived on or even penetrated in...
Regeneration, the ability to restore lost parts of the body, is a widespread phenomenon in animals. While this ability is somehow limited in classical developmental model organisms, a variety of anima...
We investigated the prevalence of animal allergy and sensitization to animal allergen among participants in international symposium of Korean association for laboratory science (laboratory...
Our objective here is to characterize the viral evolution and viral factors determining HIV virulence, the evolution of the HIV reservoir in PBMC and the co-evolution of anti-HIV CD8 T cel...
The investigators will evaluate sensitization to animal allergens and allergic symptom during contacting animal allergens in Korean veterinary researchers who attend their annual conferenc...
Assisted animal therapy (AAT) is getting more and more used worldwide, in such areas as gerontology, psychiatry, or oncology. It is a complementary therapy, and benefits for patients are v...
The aim of this study was to describe prevalence, radiologic and ultrasound evolution during pregnancy, postnatal evolution and treatment strategy in case of isolated fetal spelnic cyst
The interdisciplinary science that studies evolutionary biology, including the origin and evolution of the major elements required for life, their processing in the interstellar medium and in protostellar systems. This field also includes the study of chemical evolution and the subsequent interactions between evolving biota and planetary evolution as well as the field of biology that deals with the study of extraterrestrial life.
Evolution at the molecular level of DNA sequences and proteins. (Rieger et al., Glossary of Genetics: Classical and Molecular, 5th ed)
The techniques used to produce molecules exhibiting properties that conform to the demands of the experimenter. These techniques combine methods of generating structural changes with methods of selection. They are also used to examine proposed mechanisms of evolution under in vitro selection conditions.
The killing of animals for reasons of mercy, to control disease transmission or maintain the health of animal populations, or for experimental purposes (ANIMAL EXPERIMENTATION).
Persons who avoid consuming animal products or animal-derived substances, such as MEAT; EGGS; or HONEY. Some vegans also refrain from using animals or animal products in any form or for any purpose, such as in CLOTHING or household goods.
