Which term applies to a period in evolutionary history when a species show little or no change?
The term that applies to a period in evolutionary history when a species shows little or no change is "stasis." This concept suggests that species can remain relatively unchanged for long periods, often interrupted by brief episodes of rapid evolutionary change, as described by the theory of punctuated equilibrium.

What is Phyletic change?
Evolutionary change is a process where things change over a period of time. Such as going from a candle, to a light bulb.
Do you suspect that evolutionary change always leads to greater complexity?
No, evolutionary change does not always lead to greater complexity. Evolutionary changes can result in both increases and decreases in complexity, depending on the specific pressures and environmental conditions acting on a species. Factors such as natural selection, genetic drift, and environmental changes can all influence the direction of evolutionary change.
Current details about the evolutionary process?
Scientists currently think that the evolutionary process is ongoing. Species that cannot adapt do not survive; those that can change and evolve are more successful.
What is a branching diagram showing evolutionary change?
A branching diagram showing evolutionary change is a phylogenetic tree. It represents the evolutionary relationships between different organisms or species by showing their common ancestry and divergence over time. The branching points on the tree indicate where new species or lineages have arisen.
What theory proposes species evolve during short periods of rapid change?
Punctuated equilibrium theory proposes that species evolve rapidly during short periods of significant change, followed by long periods of stability with little evolutionary change. This contrasts with gradualism, which suggests that evolution occurs steadily over long periods of time.
The evolutionary history of a species can be displayed in a?
phylogenetic tree, which shows the relationship and divergence of different species from a common ancestor over time. Branches on the tree represent genetic or morphological changes, and the length of the branches can indicate the amount of evolutionary change that has occurred. Phylogenetic trees help researchers understand the evolutionary relationships between different species and how they have evolved over time.
Living things have a long history of change?
evolutionary change.
What is Phyletic change?
Evolutionary change is a process where things change over a period of time. Such as going from a candle, to a light bulb.
What is the term for an evolutionary change in one species that result in the evolutionary change of another species?
This phenomenon is known as coevolution, where changes in one species can drive changes in another species as they interact and exert selective pressures on each other over time.
What is the study of how species change over time?
Evolutionary science/biology.
What is difference between systematics & taxonomy?
Systematics: 1. Does not change with change in theory. 2. It deals with classification and evolutionary history. It remains same with time . Taxonomy: 1. It changes with change in theory. It deals with classification of oraganisms only,yet not evolutionary history. It doesn't remain same with time.
What are three processes that have affected the history of life on earth?
Three processes that have affected the history of life on Earth include natural selection, mass extinction events, and evolutionary diversification. Natural selection drives the adaptation of species to their environment, mass extinction events change the course of evolution by wiping out many species at once, and evolutionary diversification leads to the emergence of new species over time.
What biologist attempts to gain insight into the natural history of animals plants and microorganisms using the concept that species change over time?
the correct answer is Evolutionary or A.... for Plato Biology course
What are some common phylogenetic tree questions that researchers often explore in the field of evolutionary biology?
Researchers in evolutionary biology often explore questions related to the relationships between different species, the timing of evolutionary events, the patterns of genetic variation within and between species, and the processes driving evolutionary change. They may investigate the evolutionary history of specific groups of organisms, the impact of environmental factors on evolution, and the mechanisms underlying the diversification of life on Earth.
What is the punctuated equilibrium hypothesis about?
The punctuated equilibrium hypothesis suggests that species often undergo long periods of evolutionary stability, or stasis, interrupted by short bursts of rapid change leading to new species formation. This model contrasts with gradualism, which posits a slow and steady accumulation of changes over time.
What is the name of this type of evolutionary change?
This type of evolutionary change is called divergent evolution, where closely related species evolve into different forms to adapt to different environments or ecological niches.
Do you suspect that evolutionary change always leads to greater complexity?
No, evolutionary change does not always lead to greater complexity. Evolutionary changes can result in both increases and decreases in complexity, depending on the specific pressures and environmental conditions acting on a species. Factors such as natural selection, genetic drift, and environmental changes can all influence the direction of evolutionary change.
