Hint: Life is the inherent capacity of organisms to utilize the outside materials (light, water, gases, or food) for energy, growth, and reproduction through chemical reactions (metabolism) in a controlled manner. Biological or organic evolution refers to the changes in the properties of organisms or groups of such populations over a number of generations. It is the process of cumulative change in living populations and in the descendent populations of organisms, i.e., descent with modification.
Complete answer: All existing organisms have evolved by a similar mechanism, i.e., gradual change in the pre existing organisms. Evolution is defined as a process of gradual changes that take in primary organisms over millions of years in which new species are produced.
-Evolution cannot be equated with progress. This statement is not justified because it can't be said that the older mechanism before evolution was not efficient. Evolution has led to the complexity of the body over time but the previous mechanisms were equally efficient and it is provable with the example of the bacteria which came before the evolution and is still surviving in the present conditions.
-Bacteria inhabit hot springs, deep oceans, and ice. The body of human beings have been designed with environmental conditions and their existence is supported. According to the evolutionists, the unicellular organisms were the first to appear in the world. Some of them give rise to multicellular organisms.
-The earlier multicellular organisms were relatively simple, such as the seedless plants and invertebrate animals. The early vertebrates were fishes. Some fishes gradually changed into amphibians. Some of the latter finally evolved into birds and mammals. Humans evolved from the now-extinct ape-like animals by the accumulation of changes from generation to generation.
Note: Evolution of man from ape-like ancestors is supported by molecular and anatomical evidence besides the fossil evidence. The main changes that occured in the evolution of man include erect posture, bipedal locomotion, grasping hands, binocular vision, enlargement of the brain, rounding of the cranium, broadening of the forehead, flattening of face, etc.
