Answer 1

The most important directional "force" in evolution is natural selection, or differential reproductive success.

Under natural selection I include sexual selection. Note that other people may list these two forms of selection under separate headers. Sexual selection is when organisms display preferences for mates with specific attributes, such as a colourful plumage, or broad hips and large mammaries.

Why are acquired traits not capable of directing evolution?

Acquired traits are not passed on to offspring because they are not encoded in an organism's DNA. Evolution, which is the change in inherited traits in a population over generations, is driven by genetic variations that are heritable. Acquired traits, such as a scar or a learned behavior, do not alter an organism's genetic makeup and therefore cannot be passed on to future generations to influence evolution.


What is the biggest force driving evolution?

Natural selection, where organisms with beneficial traits are more likely to survive and reproduce, is the biggest force driving evolution. This process leads to the accumulation of adaptations over time that increase the fitness of species within their environments.


What was Einstein's theory on evolution?

Albert Einstein did not propose a theory of evolution. His primary contributions were in the fields of physics, particularly in the theory of relativity and the equation E=mc^2. Evolution is a biological theory developed by Charles Darwin to explain the diversity of life on Earth through the process of natural selection.


What is the primary function of Golgi body cell part?

The primary function of the Golgi apparatus is to process, package, and deliver proteins and lipids to their correct destinations within the cell or to be secreted outside of the cell. It modifies and sorts these molecules before directing them to their appropriate locations.
