Evolution of man can be traced on basis of studying the fossils found in sediments and success of tracing lineage hugely relies on locating first hominid during evolution.But lack of evidence is a big hurdle in declaring existing known fossils as the first hominid. Till now the earliest hominid known to all is Lucy (Australopethicus afarensis). But we are not sure if Lucy or some other fossil is the True contender for the first Hominid.
Two trophies in the article refers to the two fossils found by University OF California and French Kenyan Team. These fossils are known as Ardipithecus ramidus kadabba and Orrorian tigensis respectively.
Significance of trophies:
Name of Fossil
Artipithecus ramidus kadabba
Orrorin tigenensis
Commonly called as
Root species
Original Man
Age
5.2-5.8 million years old
6 million years old
Evidences of bipedal locomotion
Weight bearing surface of toe bone, canine small, flat wearing
Head of femur to dissipate forces, Thick enamel on tooth
Missing evidences
Absence of pelvic bones, complete femur, tibia, ankle bones,
Ape like traits
Thin tooth enamel
Orrion canine is like ape canine.
These both species are contender for first hominid, but lack of fossil evidences does not make it clear about the actual placement of each of them.
Both fossils show different mosaics of hominid and ape features. These all discoveries just tell about dynamism in study of human evolution, which may be not be as easy to be explained by a simple Y shaped branching. There is much more to be explored before we can conclude about our ancestors and their appearance on Earth.
