The addition of acetyl groups to histones is associated with chromatin condensation and and higher levels of gene expression
Answer:
1. Molecular evidence: similar proteins and genes found in closely related species, even if those genes are not used by an organism.
2. Fossil evidence: organisms changing form over time through the fossil record.
Direct observation. We can directly observe small-scale evolution in organisms
with short lifecycles (e.g., pesticide-resistant insects).
