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:

• Analyze each option:
• Option 1: Looking at the timeline, humans (Homo sapiens) are shown at a relatively recent point (5 MYA), which aligns with the idea that humans have only recently existed on Earth.
• Option 2: The fossil record shows early life forms like single - celled organisms and complex single - celled life before multicellular life. Also, life likely started in water (as per common evolutionary understanding and the timeline which shows water - related events like "Earliest water" at 4.3 BYA and life - related events like "Life on" at 3.8 BYA). Organisms did not originally live only on land.
• Option 3: Water formed at 4.3 BYA and life started at 3.8 BYA. So life on Earth started after water formed on Earth.
• Option 4: Complex single - celled life (like Complex single - celled life at 2.8 BYA) evolved before multicellular life (Multicellular life at 1.2 BYA).

Answer:

Humans have only recently existed on Earth.
