Question

study the timeline.
which statement indicates what the fossil record suggests about evolution on earth?
humans have only recently existed on earth
organisms originally lived only on land.
life on earth started before water formed on earth.
multicellular life evolved before complex single - celled life.

Explanation:

• Option 1: The timeline shows humans (5 MYA) compared to much earlier life forms (e.g., single - celled life 4.1 BYA). This indicates humans are recent.
• Option 2: Earliest life (single - celled) was likely in water (earliest water 4.3 BYA), not on land.
• Option 3: Earliest water (4.3 BYA) is before single - celled life (4.1 BYA) according to the timeline.
• Option 4: Complex single - celled life (2.5 BYA) is before multicellular life (600 MYA).

Answer:

Humans have only recently existed on Earth.
