"Clade" Natural Recordings by Native Speakers
A clade is a group of organisms that includes a common ancestor and all of its descendants. It is a fundamental concept in biology and taxonomy, and is often used to describe the relationships between different species or higher-level taxonomic groups. In essence, a clade is a lineage or a branch on the tree of life that shares a common ancestor and exhibits a distinctive set of characteristics or traits. Clades can be used to define and categorize organisms in a hierarchical system of classification, helping to understand their evolutionary relationships and patterns of divergence.
A clacker is a type of noise-making toy typically designed for young children, consisting of two or more parts that strike each other to produce a sound when moved or shaken. The sound produced is often a loud, improvisational clang or rattle.
Clackers are a type of children's toy that consists of a pair of small objects, usually plastic or wood, connected by a string or chain. They are designed to be swung back and forth, often in a rhythmic motion, and are often used as a fidget toy or to provide a soothing sensory experience.
The verb "clacking" refers to the loud, sharp, and sudden sound of two surfaces being struck together, often with a sharp, repetitive, and rhythmic motion. For example, the sound of a typist's fingers striking the keyboard keys, or the noise of two pieces of wood being struck together with a hammer. It can also refer to the act of making this sound, as in "to clack one's jawbone in annoyance".
Clad refers to clothed or covered with something, especially clothing or armor. It can also mean covered or wrapt in a particular material or substance, such as clad in steel armor or clad in the finest silk.
Cladistic refers to the study of the evolutionary relationships between organisms based on the sharing or lack of shared derived characteristics, known as synapomorphies. In cladistics, the goal is to reconstruct the evolutionary history of a group of organisms by analyzing the presence or absence of these shared characteristics, with the aim of deducing the most recent common ancestor of the group. The scientific discipline uses a strict, hierarchical approach to classification, grouping organisms solely based on their shared derived characteristics, without considering other factors such as anatomy, physiology, or behavior.
Cladocera refers to a group of small, freshwater crustaceans commonly known as water fleas or pond fleas. They have a segmented body and typically range in size from 0.1 to 10 millimeters. Cladocera are found in both calm and fast-moving waters and are an important food source for many aquatic animals, such as fish, frogs, and birds.
