Introduction

Evolutionary scientists believe that all living things are as a result of various evolutions occurring due to climatically and environmental changes over a long period of time . Studies show that the hominid is the word used to refer to human family which consist of human and ape ancestors (Niles , 2005 . There are various studies touching on the macroevolution of hominids and though fragmented there is tangible evidence to prove evolution

of human history . This is written to critically analyze the concept of macroevolution of Hominids

Hominid species in this will be recorded in terms of appearance in the fossil records

Sahelanthropus tehadensis : This species was discovered in 2002 from fossils found in Chad which is a country in Central Africa (Cameron 2004 . This species is deemed as one of the oldest fossils in the world since its existence dates 6 to 7 million years ago . The features of the fossils showed fragmented lower jaws and teeth , the brain was very small of approximately 350cc (Haviland , 2003 . This species also had very small canine teeth and from its structure it can be argued that it came from the chimpanzee and human ancestors (Cameron , 2004

Orrorin tugensis : This species was discovered in western Kenya a country in the African continent in 2001 (Haviland , 2003 . The fossils include fragmentary arm , teeth , thigh bones which date back to 6 million years old and its structure...
