World Online Debate Cup-Evolution is true

REBUTTALS1. Fossils: Transitional fossils between reptiles and birds, reptiles and mammals, and primates to humans have actually been found. [1] In fact, there are no known gaps between dinosaurs and birds. [1] This falls in line with the definitions of evolution. Also, if we assume evolution to be true, then every fossil is a transitional fossil, between two or more species. However, the transitional fossils do line up, against the assumption that evolution is false. Thus, the argument is easily refuted. 2a. FetusesOkay. Then explain all of these images. It is impossible that the same guy drew all of these. Oh, and my opponent forgot to rebut my pictures of Trilobites.2b. Similar anatomical featuresMy opponent is only half correct. The full statement goes like this:P1: If there are similarities between skeletal structures, it can only be explained with evolution, or common ancestry.P2: There are similarities between skeletal structures.C: Evolution is true, or common ancestry is true.PP1. If common ancestry is true, but many species look different and are different, then evolution is truePP2. Common ancestry is true ("same creator"), but many species look different and are differentC2: Evolution is true2c. Whale PelvisThis is an interesting point. There is no reason to suppose a land mammal's pelvis shrunk through evolution, neither is there evidence of this.This is what I was trying to prove (not enough characters last round):P1: If and only if evolution is true, then we should see new species forming.P2: We see new species forming.C: Evolution is (likely) true.(Whales form from...whatever was before it, therefore evolution is true)However one example is simply not enough. Here are two more examples:1.Drosophila paulistorum Drosophila paulistorum is a type of fruit fly which had a speciation event sometime between 1958 and 1963. Crosses with other strains only produced sterile hybrid flies, meaning that the fruit fly are a new species.2. GoatsbeardsGoatsbeards are wild flowers introduced from Europe to America. Three species were initially introduced, which interbred, but could not produce fertile offspring. (The hybrids were sterile), meaning that they were 3 different species. In the 1940's, two new species of goatsbeards appeared, which produced fertile offspring only when breeding within their species, and not with the species it evolved from.[2] This is proof that they are different species.2d. Chromosome 2 merged? Oh yes, there is evidence. Source [3] gives evidence within professional research that chromosome 2 fused together. :D3. Geo-distributionUm, but the turtles are a different species and the finch as well. It's kind of like my dog point, you know. They have different traits but dogs are still dogs!4. Genetic changes:Natural selection explains evolution. Only the toughest survive. If different situations keep on happening, a new species must be created and sustained in order to survive, which is evolution in its core. My opponent fails to come up with the conclusion that natural selection equals to evolution!!My opponent has failed to rebut my point about overall similarity (7 points!) that all life share, as well as the human-ape DNA similarity.I would like my opponent to please take his time and work on a longer rebuttal.[1] http://www.talkorigins.org...[2] http://www.talkorigins.org...[3] http://etb-darwin.blogspot.com...
