An evolutionary trade-off occurs when there is a compromise between two traits that cannot be optimized simultaneously. For example, investing resources in growing a larger brain may come at the expense of producing fewer offspring. Evolutionary trade-offs are the result of limited resources and competing selective pressures.

In a cladogram when does a group of organisms branch off?

A group of organisms branches off in a cladogram when they share a common ancestor that is different from other groups on the cladogram. This branching represents the point at which their evolutionary paths diverged.


What is the word for an organism's evolutionary history?

The word for an organism's evolutionary history is its phylogeny. Phylogeny represents the evolutionary relationships and history of a group of organisms.


Type of classification based on evolutionary history?

Phylogenetic classification is based on evolutionary history and relationships among organisms. It organizes species into groups based on shared ancestry and evolutionary relationships, using information from genetic and morphological similarities. This approach helps to study the evolutionary development and relationships among different species.


How does evolutionary classification differ from traditional classefecation?

Evolutionary classification groups organisms based on their evolutionary relationships and ancestral history, while traditional classification focuses on similarities in observable characteristics. Evolutionary classification aims to reflect the evolutionary history of organisms, while traditional classification is based on shared physical characteristics. As a result, evolutionary classification can provide a more accurate depiction of the genetic relatedness among species.


What is the name for this type of rapid evolutionary change?

The name for this type of rapid evolutionary change is "punctuated equilibrium."
