1 Homologous structures are structures found in plants or animals that have the same origin, but not necessarily exactly the same form or the same function. 2  The development of homologous structures is an example of divergent evolution.

A species is a group of similar living things, such as lions, that can breed together. If a group of individuals within a species becomes separated from all the other groups of that species, they can no longer breed with them. In time, the group evolves separately and becomes increasingly different.

Evidence suggests that the earliest life forms arose on Earth around 3.5 billion years ago. Since that time, many different organisms have lived on Earth. A record of their existence can be found as fossils preserved in rock. Fossils are the remains or traces of once-living organisms. They can include shells, teeth, bones, footprints, leaf impressions, and petrified wood. Scan these images for fossils you can recognize. 1. Write down the name of at least one of the fossils that you think you can identify. !

1 Many fossils have been found which appear to have the characteristics of two different groups of organisms. 2  These fossils are called transition fossils. 3  Homologous structures are structures found in plants or animals that have the same origin, but not necessarily exactly the same form or the same function.

The fossil record shows that species have changes over time because  they show organisms that are very similar to ones today. They also  show organisms that are not like org … anisms that live today. 4 people found this useful. Melissa MacFarlane.

The fossil record demonstrates clearly that changes have occurred in animals and plants across the millennia. Further, the changes can be followed in the fossil record, and this demonstrates evolution in action.

22. Outline the theory of evolution by natural selection as proposed by Darwin and Wallace. 23. Describe the evidence for evolution including fossils, transitional forms, comparative embryology and homologous structures (the pentadactyl limb) and biochemical similarities.

1 A fossil is a preserved remnant or trace of a once living organism. 2  Fossils are typically found in sedimentary rocks. 3  Usually it is the ‘hard parts’ of plants and animals that are preserved e.g. wood or bones or shells, as the ‘softer parts’ e.g. flesh are usually decayed (decomposed by bacteria, etc.) or eaten.

Fossils are a doorway to the past. They show us what was, and by tracing through the layers in which they are preserved and looking at the various types, we can follow changes … in the characteristics of life through time.

how do fossils show how organisms have evolved through time?
Fossils are the remains or traces of living organisms and by scanning that traces one can show evolution of that organism.
