Primates_1

Primates

A group of mammals that includes monkeys, apes, and humans, characterized by traits such as large brains and forward-facing eyes.

Homology

The similarity in traits due to shared ancestry among closely related species.

Adaptive radiation

The evolutionary process in which organisms diversify rapidly into a multitude of forms to adapt to different environments.

Vestigial traits

Anatomical features that have lost their original function in a species, such as the human appendix or wisdom teeth.

Convergence

The evolution of similar traits in unrelated species due to similar selective pressures, resulting in analogous structures.

Stereoscopic vision

A type of vision that allows for depth perception, where both eyes perceive the same image, providing a 3D view.

Prehensile limbs

Limbs that are capable of grasping; an important adaptation in primates for climbing and manipulating objects.

Ancestral traits

Characteristics that have been inherited from common ancestors of a group.

Derived traits

Newly evolved traits that were not present in the ancestral lineage and help to distinguish a group from its ancestors.

Phylogenetic constraints

Limitations on the evolutionary direction of species due to their historical relationships and traits inherited from ancestors.

Dental formula

A notation that indicates the number and types of teeth in an organism, often used to differentiate between primate species.

Cognitive abilities

Mental capacities that involve the processing of information, learning, problem-solving, and memory, often studied in primates to understand evolution.

Prosimians

The suborder of primates that includes lemurs, lorises, and tarsiers, typically characterized by their reliance on olfactory cues.

Anthropoids

The suborder of primates that includes monkeys, apes, and humans, recognized for their larger brains and more complex social structures.

Bipedalism

The ability to walk on two legs, a distinguishing trait of modern humans and pivotal in human evolution.

Genome sequencing

The process of determining the complete DNA sequence of an organism's genome, providing insights into evolutionary relationships.

Linnaean classification

A hierarchical system used by biologists to categorize and name living organisms, established by Carl Linnaeus.

Evolutionary history

The sequence of historical events through which species have evolved, often presented as a family tree or phylogenetic tree.

Social structure

The organization of individuals within a society, often influencing behavior patterns in species such as chimpanzees and bonobos.

Mosaic evolution

The concept that different traits in a species may evolve at different rates, leading to a diverse range of physical and behavioral characteristics.
