Early Hominins are the hominin species recognized as the first species of the genus homo and lived approximately 2.5-1.8 million years ago.
Between 2.5 and 3 million years ago, the genus Homo initially made its appearance. For a long time, Homo habilis fossils were thought to be the oldest specimens of the genus Homo for a long time, but in 2010, a new species dubbed Homo gautengensis was found and maybe older.
Homo: a genus. The earliest remains of our own genus, Homo, date to 2.3 mya and are located in East Africa (Kimbel et al. 1997). These early individuals share the same size of the brain and body as Australopithecus, but their molar teeth differ, indicating a shift in nutrition.
The genus Homo belongs to the family Hominidae (order Primates), and it is distinguished by a relatively large cranium, limb anatomy that is suited to a habitual upright position, and a bipedal walk.

<h2>Ecological species concept</h2>
Explanation:
Ecological species concept is the concept of species where species is a group of organisms adapted to specific resources,called niche in the environment
- Every species has a different niche;niche is simply the role played by the organisms in a particular area(environment) in which it is living
- Ecological and evolutionary processes controls the resources and divides the species into groups
- In the given example members of one population of wolf spiders are found in leaf litter within the woods while the other one is found in the grass at the edge of the woods
- Both the members are distanced from each other ecologically and their role to use resources changes
- Hence they are designated as two different species by utilizing the ecological species concept
A. Chloroplasts are where photosynthesis occurs.
