Evidence of Evolution (pgs 28-37)

The remains or imprints of once-living organisms in layers of rock are:

• record

• fossils

• cells

• common structures

Study the picture on horses and their ancestors. Fossil evidence shows that life on Earth has changed over time (evolved).

How do similar bone structures provide evidence that evolution has taken place?

• Organisms that have similar structures in their bones supports that they share a common ancestor.

• Fossils show when organisms used to live.

• Fossils have shown that the Earth is only six-thousand years old.

Which of the following are clues that supports evolution?

• Fossil evidence- shows how species have changed

• Common structures- similar bones in human arm, cat leg, bat wing

• Similar DNA- chimpanzee and humans share 98% DNA

• Developmental Similarities- embryos in different species look similar

• All the above

This picture suggest that:

• humans, cats, whales and bats share a common ancestor.

• humans, cats, whales and bats use these bones in the same way.

• humans, cats, whales and bats have little in common.

According to this chart, humans are most closely related to:

• chimpanzee

• rhesus monkey

• yeast

Look at the chart. Humans and chimpanzees have zero difference for the amino acid- Cytochrome C. We are still a different species, because our bodies make many other amino acids.

• true

• false

• false
