Fossil Evidence of Evolution

Archaeopteryx/Urvogel is a transition fossil between what two species?

• birds and dinosaurs

• land animals and fish

• birds and bees

• bacteria and cells

Answer explanation

Archaeopteryx, also known as Urvogel, is a transitional fossil that demonstrates the evolutionary link between birds and dinosaurs. It possesses features of both groups, such as feathers and a wishbone like birds, and a long bony tail and teeth like dinosaurs. This makes it a crucial piece of evidence in understanding the evolution of birds from their dinosaur ancestors.

Order the fossils according to their relative age from oldest to youngest.

• 1,2,3,4,5

• 5,4,3,2,1

• 5,3,4,1,2

• 2,1,4,3,5

Answer explanation

The correct order of fossils according to their relative age from oldest to youngest is 5, 3, 4, 1, 2. This sequence represents the proper arrangement of the fossils based on their age, with the oldest fossil being first and the youngest fossil being last.

What is the fossil record?

• All the fossils ever discovered on Earth

• a chart that divides Earth’s history into different time units.

• when the last individual organism of a species dies

• fossils that have characteristics of both ancestral organisms and organisms that evolved

Answer explanation

The fossil record refers to all the fossils that have been discovered on Earth. It is a cumulative collection of all the remains or impressions of plants, animals, and other organisms preserved in rock. The other options do not accurately define what the fossil record is.
