Eyes are easy. Just look at all the intermediates. From eye spots to cup eyes past pinhole eyes all the way to camera eyes. This progression easily shows the concept of descent with modification.
The products of evolution include the diversity of species, adaptation to environments, and the development of complex biological structures and functions. Evolution also leads to the formation of new species through the process of speciation.
An organism becomes more complex over time through a process called evolution. This involves genetic changes that accumulate over generations, leading to the development of new traits and structures that increase the organism's complexity and adaptability to its environment.
The theory of evolution has many criticisms but none have proven evolution wrong. For example, some people argue that the bacterial flagellum is 'irreducibly complex' and therefore can not have evolved, even though the evidence shows that it not only could have, but has.
The process of change that produces a more complex organism is called evolution. Evolution occurs through the accumulation of genetic variations over generations, driven by natural selection and other mechanisms like genetic drift and gene flow. This process leads to the development of new traits and structures that enhance the organism's survival and reproduction in its environment.
Some potential problems in the theory of evolution include gaps in the fossil record, the origin of complex structures like the eye, and understanding the mechanisms driving rapid evolutionary changes. Additionally, determining the exact mechanisms of speciation and the role of epigenetics in evolution are ongoing challenges.

Evolutionary trends are either progressive or retrogressive. During progressive evolution new structures are created whereas in retrogressive evolution the existing structures are reduced or eliminated.
Explain the need for complex data structures
Complex cellular structures appeared around 2 billion years ago during the Proterozoic Eon. This period marked the evolution of eukaryotic cells, which are characterized by membrane-bound organelles and a true nucleus.

yesIt is not associated with synthesis. It is associated with modification and transportation
Yes ... but nowhere near as complex as sexual reproduction.
An oxygen-based metabolism provides more energy than an anaerobic metabolism, allowing for a larger volume-to-surface ratio of organisms. So organisms could grow larger, allowing their tissues to specialize in various ways, which means increasing complexity.
Is it the elemental evolution, a chemical evolution, a nuclear evolution or a molecular evolution? Please choose one of the following.
