The use of antibiotics and pesticides.
Yes. Animals are composed of chemicals. Chemical evolution typically refers to stellar nucleosynthesis, the creation of elements by nuclear fusion in the cores of stars, and the synthesis of elements heavier than iron via star bursts--supernova. Biochemical evolution would refer to the formation of more complex molecules, such as the spontaneous generation of amino acids from less complex molecular arrangements.

Chemical
Chemical evolution suggests that simple inorganic molecules eventually led to the formation of more complex organic molecules, such as amino acids and nucleotides. Over time, these molecules evolved into the building blocks of life, including proteins, DNA, and ultimately, living organisms.
This is a sign of a chemical reaction.

Metabolic activity is the activity in which the chemical transformations occur within the cells of living organisms. Metabolic activity is used to maintain an organisms life.
Biological evolution is the process of changes that occur in living beings that can be passed on to their offspring. Chemical evolution is the process of changes that occur in substances. However, scientists have found that these substances have changed to form organic molecules, meaning that they have created life from nonliving substances.
Quartz is a mineral that is highly resistant to chemical weathering. Marble is a mineral that is more susceptible to chemical weathering.

DDT is a persistent chemical because it is resistant to degradation by natural processes like sunlight, heat, and microorganisms. This allows it to remain in the environment for a long time, accumulating in organisms and biomagnifying through food chains.
The word evolution is a noun derived from the verb 'to evolve', which means to change over time. In science, only one type of evolution is given the title evolution in a special sense, where in a scientific context it refers solely to the changing of living organisms, the evolution of living organisms through genetic changes in populations which lead to adaptations which lead to speciation, all over long periods of time. Chemical evolution may sometimes refer to the mishmash of carbon based chains and forming aminoacids in the Precambrian seas prior to true life-formation; abiogenesis. It is not a special term of 'evolution' as that only occurs in the biological sense. It is therefore an evolution from the sense of the verb 'evolve' which merely unspecifically denotes a change.
Scientists believe that chemical evolution occurred around 3.5 billion years ago.
Chemical activity
Chemical evolution: the evolution of the elements (building blocks of matter) biological evolution: the small scale change in a population that can be passed from generation to generation Both of these are changes that occur to gradually create a new species or substance
The theory that life started itself from the chemical properties of matter is called abiogenesis. Abiogenesis proposes that living organisms can arise from non-living matter through natural processes such as chemical reactions.
