Heredity and Evolution
Heredity, the passing of traits, and evolution, the change in species over time, together explain the diversity and adaptation of life on Ea
Core concept
Genetic inheritance follows patterns established by Mendel's laws, with dominant and recessive alleles determining observable traits in offspring.
How it works
Evolution occurs through natural selection, where organisms with advantageous traits are more likely to survive and reproduce.
Why it matters
Evidence for evolution includes fossil records, comparative anatomy, and genetic similarities between related species.
Key detail
Understanding heredity and evolution helps explain biodiversity, adaptation, and the interconnectedness of all living organisms.
