Evolution does not occur as a response to the needs of the organism. It is not driven by individual organisms adapting to their environment, but by the process of natural selection acting on variations within a population over time.

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 evolutionary barrier causes an infertile offspring?

An evolutionary barrier that could cause an infertile offspring is genetic incompatibility between the parents, leading to mismatched or non-viable offspring. This can occur when different species attempt to reproduce, resulting in a hybrid that is infertile. Additionally, mutations or chromosomal abnormalities can also lead to infertility in offspring.


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

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