Doing research on government and university websites provides honest answers to questions about evolution. Another good option is to consult science professors at local universities.
The National Science Foundation website provides an overview of information on evolution. Another credible source would be research university-sponsored websites which present the information categorized by topic.
If doing research online does not answer every question, science professors from universities are usually accessible by email and are willing to help people learn. Their email addresses are typically available on the university's website, and as they are experts in their fields, their answers are credible and honest.
