1
New cards

Fossil record

preserved remains showing species change and transitional forms.

2
New cards

Homologous structures

body parts with the same structure but different functions (evidence of common ancestry).

3
New cards

Analogous structures

body parts with different structures but similar functions (result of convergent evolution).

4
New cards

Vestigial structures

body parts that have lost their original function (e.g., human tailbone).

5
New cards

DNA/genetic evidence

similarities in genetic code across species indicate shared ancestry.

6
New cards

Observed evolution

measurable changes happening today (e.g., antibiotic resistance, peppered moths).
