What role did cyanbacteria play in the evolution of life on earth?
The role of raising atmospheric oxygen to so high a level that multicellular and complex organisms could evolve. Oxidative phosphorylation generates the energy through ATP that larger and more complex organisms need.
What kind of cell did life first begin as?
It is likely that the earliest kind of cell resembled a bacterium. That is the simplest type of cell, in terms of general structure, and evolution proceeds from the simple to the complex.
Why are complex organisms made up of specialized cells?
Complex organisms need cells that perform many different functions. Complex organisms are capable of a lot of different things, and that variety needs to be supported on the cellular level. Without them, complex organisms cannot perform different functions.
Will advanced organisms be the same as complex organismswhy?
The complexity of body design will increase over evolutionary time. This is the process by which new modifications occur in the organisms. So, in this way we can say that advanced organisms will be complex as compared to complex organisms...
Explain what the terms eukaryote and prokaryote suggest about their evolution?
The terms eukaryote and prokaryote refer to the two distinct types of organisms found in the natural world. Eukaryotes are organisms that have a membrane-bound nucleus, while prokaryotes are organisms that lack a membrane-bound nucleus. This difference in structure suggests that the evolution of eukaryotes, which are more complex and structurally organized, preceded the evolution of prokaryotes, which are simpler and more primitive. Eukaryotes are believed to have evolved from an ancestor that contained a nucleus, which was a critical step in the evolution of life as it allowed for more efficient storage and processing of genetic information. Prokaryotes, on the other hand, had no nucleus and were likely the first form of life on Earth. This suggests that the evolution of prokaryotes followed the evolution of eukaryotes. Overall, the terms eukaryote and prokaryote suggest that eukaryotes are more complex and evolved prior to prokaryotes, which are simpler and more primitive.
What is the order of evolution from the simplest to most complex?
The earliest cells came before the most complex organisms existing today. :]
Why did the earliest organims in the fossil record start off single celled?
It took many years of evolution for complex, multi-celled organisms to develop. Single celled organisms were the first that were around to be fossilized.
Is the process of change that occurs during an organisms life to produce a more complex organism.?
evolution
What is generally accepted as the origin of living organisms?
Prebiotic chemical evolution gave rise to progressively more complex molecules and eventually to living organisms
What role did thee appearance of the ozone layer play in the evolution of early life?
Ozone played a vital rose after appearance. It led to evolution of complex organisms.
What is a Evolutionary Trends?
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.
What was the significance of the development of chloroplasts?
The development of chloroplasts led to the oxygenation of Earth's atmosphere, which allowed the evolution of more complex oxygen-breathing organisms.

Does evolution optimize the quality of life?
No. Evolution is the change in allele frequency over time in a population of organisms. Things, generally, not always, tend to get more complex, but " optimize the quality of life " has no biological meaning.
How could evolution of aerobic respiration have permitted evolution of more complex organisms?
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.
How does Lamarck explain that organisms have a tendency to adapt and improve yet throughout the world the lowest forms of life still exist?
Obviously he was wrong. Organisms evolve, Evolution is not progressive, does not plan for the future and is not linear. The average tendency is for organisms to become more complex, but someone forgot to tell barnacles and tape worms, among others, as they have got less complex. Evolution is only change over time and Lamarck was wrong about ' improvements. '
