ANATOMICAL EVIDENCE
PIECE OF NEWS
This australopithecine is Lucy, a 3.2 million-year-old fossil discovered in 1974 about 70 kilometers from where Ardi was found.
An international team of scientists presented what they say is the oldest and best-preserved fossil of a direct ancestor of the human species
After recovering several important bones, researchers were able to calculate it’s weight and height, and they believe that Ardi walked on two legs on the ground, although it was climbing trees and passing a long time in them
-
The most surprising thing, they say, is that the proportions of its limbs were not similar to those of chimpanzees or gorillas, but to those of now extinct apes
TYPES
Analogous organs:
-
-
They have a originally different structure, but they have taken on a similar appearance in evolution.
-
Vestigal Structures:
-
-
At some point during evolution, these body parts were no longer necessary for survival and they disappeared or stopped functioning.
-
Homologous organs:
They have a similar structure,
These organs can be used as an example of Divergent Evolution in which the organisms have common ancestors but later on, result in different species.
They do not look exactly the same, or have the same function.
-
WHAT IS?
Anatomical evidence of evolution focuses on similarities and differences in the structures of different species. Some species seem very different however they can have similar elements. These similarities could mean that the two species had a recent common ancestor.
