I would say pretty much everything. If it's living it obviously has to go through some kind of change.
Differentiation occurs several times during the development of a multicellular organism. The organism changes from a simple zygote to a complex system of tissues and cell types.

Mutations can improve the trait, harm the trait, or neither.
Acquired characteristics acquired during an organism's lifetime cannot be passed on to offspring according to modern evolutionary theory. Evolution is driven by genetic variations that are inherited and can lead to changes in a population over time through natural selection.
Examples of traits gained during an organism's life (acquired traits) include skills learned through experience, such as playing an instrument or riding a bike. Additionally, environmental factors like exposure to sunlight can affect skin tone. These traits are not determined by an organism's genetic makeup and are developed during an individual's lifetime.
The series of changes that an organism undergoes during its lifetime is called its life cycle. This includes stages such as birth, growth, reproduction, and death. Each species has a unique life cycle.
developmental anatomy
One major flaw in Lamarck's theory was the idea of inheritance of acquired characteristics, which proposed that an organism could pass on traits acquired during its lifetime to its offspring. This concept has been disproven by genetics, as changes to an organism's phenotype during its lifetime cannot be passed on to future generations through its genes. Additionally, Lamarck's theory did not account for the role of natural selection in driving evolutionary change.

Stellar evolution is the term for the changes a star undergoes during its lifetime.
Mutations can improve the trait, harm the trait, or neither.
At first, because it could not be shown that changes to the organism acquired during its life were inherited by its offspring. Later, when we learned more about genetics, and ultimately DNA, this rejection was confirmed. Note though that since a few decades, we know of mechanisms that *do* allow certain changes at the molecular level acquired during the organism's lifetime to be inherited by offspring. This field of study is called: epigenetics.

development
An individual typically passes through four key developmental stages in a lifetime: infancy, childhood, adolescence, and adulthood. These stages are characterized by physical, cognitive, emotional, and social changes that occur as a person grows and matures.
