When evolution was first proposed, which of the following was used as evidence to support the idea?

A)observations of nature
B)laboratory experiments
C)extensive fossil collections
D)genetic sequences

Is it A or C??? I'm very torn between the two. pls help asap! i might post more. thanks

trust me i got a hundred!!!!! CA

Well, I have a difficult time understanding the question. "When evolution was first proposed..". My guess is your teacher is thinking of Darwin, and his Origin of the Species. In that case, answer A is on target.

Boo ill see if your correct

and I will not lie
good luck to me *crosses fingers*

24. Name two types of evidence used to support the theory of evolution. Explain how scientists use each type of evidence to provide support for evolution. Give one example of each.

Answer: Fossils can provide evidence of the features of extinct organisms that can help scientists locate common ancestors of present-day species. For example, the fossil of a dinosaur that has characteristics of birds and reptiles helped scientists understand that present-day birds and reptiles share this common ancestor. Comparison of DNA sequences from different organisms also provides evidence of evolutionary relationships. Organisms that have only recently split away from each another have DNA sequences that match very closely, while organisms that split long ago have greater DNAsequence differences. For example, the gene for a protein found in a horse will overlap in sequence fairly well with the gene from a cow, but will not overlap very well with the same gene from an earthworm.

25. What is a cladogram? Explain how a scientist would use DNA or protein sequences taken from three different organisms to construct a cladogram.
Answer: The scientist obtains either the same gene or the same protein from each of the three organisms. Then the sequence of the DNA or protein is determined and the three sequences are lined up and compared to see how well they match. The greater the match between any pair of sequences, the closer the linkage is between the two organisms. The greater the difference in sequence, the more distant the relationship. Once it has been determined how close or distant the relationship is between all of the organisms, a diagram is created that resembles a branched tree. Organisms are placed on closely linked branches if they have a strong match in sequence, while organisms with poorly matching sequences are placed on branches much farther away from one another.

A is the answer. I'm taking the test what are the answers for the other questions

well.....is it right??

Chun Li, Boo is always right.

He was right but I got 2 wrong I think it was question 21 and I don't know the other one

it's right I got all but one right and that is #22. overall it was right

B o o no literally boo U-U
