Really only natural selection can provide an adaptive direction to evolution. Both gene flow and genetic drift can change allele sequences over time in populations but that is not enough to bring about speciation in those populations. Only natural selection gives you the adaptive change and directional selection that creates new species.
What else can I help you with?
Is it true that Humans are responsible for the direction of evolution during the process of artificial selection?
Yes, humans are responsible for selecting desirable traits in plants and animals through artificial selection, which can influence the direction of evolution. By selectively breeding individuals with preferred traits, humans can drive the evolution of domesticated species in a specific direction.
Is evolution considered progressive in the scientific community?
In the scientific community, evolution is not necessarily considered progressive in the sense of always leading to improvement. Evolution is a process of change and adaptation over time, driven by natural selection and genetic variation. It does not have a predetermined direction or goal of progress.
Can you recommend a book about human evolution that provides a comprehensive understanding of our species' development over time?
One highly recommended book on human evolution that provides a comprehensive understanding of our species' development over time is "Sapiens: A Brief History of Humankind" by Yuval Noah Harari. This book explores the history of Homo sapiens from the emergence of our species to the present day, covering key milestones in human evolution and societal development.
What is evolution best categorized as?
Evolution is best categorized as a scientific theory that explains how species change over time through the process of natural selection and genetic variation. It provides a framework for understanding the diversity of life on Earth.
Why do most scienists think about the rate of evolution?
Scientists are interested in studying the rate of evolution because it provides insights into how species have changed over time. By understanding the pace at which genetic variations accumulate in populations, researchers can better comprehend the mechanisms driving evolution and its impacts on biodiversity. The rate of evolution can also inform predictions about how species might respond to environmental changes.
What provides direction and focus to the planning?
The commander assessment provides direction and focus.
What provides direction and focus to the planning process?
The commander assessment provides direction and focus.
Does the environment dictate only the direction and extent of evolution?
The environment is the ' natural selector ' of all variation. This is evolution.
Is it true that Humans are responsible for the direction of evolution during the process of artificial selection?
Yes, humans are responsible for selecting desirable traits in plants and animals through artificial selection, which can influence the direction of evolution. By selectively breeding individuals with preferred traits, humans can drive the evolution of domesticated species in a specific direction.
What is scalar data type?
Scalar data is the opposite of vector data, in that it provides a magnitude without a direction. For example, speed is a scalar quantity because it provides magnitude without a direction, whereas velocity is a vector quantity because it provides the magnitude that speed provides, but supplies us with direction.
What direction of friction acts in a direction to the direction of the objects motion?
Friction provides a retarding force. It always acts in the exact opposite direction of the motion of the object.
Compare lamarck's and Darwin's ideas about evolution takes place?

How does the 2nd law of thermodynamics make evolution impossible?
The second law does NOT make evolution impossible. It just requires that as evolution takes place that there be an increase in entropy of the universe as a whole.
What determines the direction and rate of evolution?
Natural selection: the interaction between organism and environment.
How and why does natural selection drive the evolution of eukaryotes?
It is often believed that species evolve to become better and become an ultimate organism.This is a misconception. Evolution becomes parallel and takes place simultaneously in different species. Evolution may also be continuous mutation. Evolution takes place simply to ensure better survival in the current habitat.
What is the slow change of living things into new forms?
Evolution takes thousands of years. Metamorphosis takes weeks or months
What it takes a force to change?
It takes a force to change an object's motion or shape. This force can cause the object to accelerate, decelerate, or change direction. The size and direction of the force determine the extent and nature of the change.
