Answer: Numerous transitional forms have so far been found. In the clade of apes alone, the number of intermediate fossils is large enough to allow for a near-complete understanding of the evolutionary history of Man and the other apes.
Answer: Yes. "However" is a logical transition word, ie it works as a logical connection between two phrases and/or ideas. Logical transition words can demonstrate the relationship between ideas in terms of purpose, time etc. "However" is a transition word which demonstrates the contrast between ideas. For example:
"China is technically a democracy. However, it displays many elements of a dictatorship."
In this example, the first idea (ie that China is a democracy) contrasts with the second idea (ie that China is a dictatorship). The use of the word "however" shows that the ideas are connected, but that the information contrasts. Consider the effect on the above example if the word "however" was omitted:
"China is technically a democracy. It displays many elements of a dictatorship."
Here, two conflicting ideas are expressed together, but are totally unconnected. Though the sentences make sense, using the word "however" as a logical transition clarifies the relationship of the sentences, and so makes the information clearer. This shows the function of logical transitional words such as "however".
Examples of logical transitions which can serve the same function, or a similar function, as "however" include:

Answer: Transitional Words and Phrases bring coherence to a paragraph by linking the idea in one sentence with that in the next sentence. They accomplish this linkage through revealing the relationship between the ideas. They often signal the reader to remember what has been said or to look forward to new ideas. With transitions, prose may achieve a smooth flow of thought; without transitions, it may degenerate into jerkiness and choppiness.
