Summary
In 1698, Edward Tyson dissected a juvenile chimpanzee, comparing its anatomy to humans and apes. This detailed study, "Orang-outang sive Homo sylvestris," pioneered comparative anatomy methods.
Area of Science:
- Anatomy
- Primatology
- History of Science
Background:
- In 1698, a unique specimen with human and ape-like characteristics was brought to London from West Africa.
- The Royal Society commissioned physician and anatomist Edward Tyson to dissect the juvenile chimpanzee after its death.
Observation:
- Tyson, with William Cowper, conducted a meticulous dissection of the chimpanzee.
- Detailed written and graphic records of the dissection were compiled.
Findings:
- Tyson's 1699 publication, "Orang-outang sive Homo sylvestris," presented a comparative analysis of the chimpanzee's anatomy against humans, apes, and monkeys.
- The study documented numerous resemblances and distinctions between the chimpanzee and humans, notably in brain and pelvic structures.
Implications:
- Edward Tyson's monograph serves as a foundational text-book example of the comparative anatomical method.
- The work represents a significant, yet under-recognized, contribution to early primatology and anatomical research.

Synteny and Evolution
3.7K
John H. Renwick first coined the term “synteny” in 1971, which refers to the genes present on the same chromosomes, even if they are not genetically linked. The species with common ancestry tend to show conserved syntenic regions. Therefore, the concept of synteny is nowadays used to describe the evolutionary relationship between species.
Around 80 million years ago, the human and mice lineages diverged from the common ancestor. During the course of evolution, the ancestral...

Sutures of the Skull
9.8K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Phylogeny
56.5K
Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.

Changes in the Appendicular Skeleton with Age
3.3K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Convergent Evolution
31.2K
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.

Anatomical Terminology
24.5K
Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...
