An anthropologist finds a fossil that is 4 million years old. its pelvis suggests it walked upright. which species could the specimen belong to?
answer choices are
australopithecus africanus
australopithecus afarensis
homo habilis
homo erectus

Option B, Australopithecus afarensis

Explanation:

Australopithecus afarensis is one of the oldest and long lived species of early human being with small canine teeth and a body which consists of two legs and walked upright regularly.  

Their body shape followed bipedalism and it comes from skeletal fossils inclusive of articulation and femur just like human beings. Their fossilised footprint showed that they it do not have knuckle-dragging impressions

Hence, option B is correct

the elements of art are the visual tools that the artist uses to create a composition. these are line, shape, color, value, form, texture, and space.

the principles of art and design are balance, contrast, emphasis, movement, pattern, rhythm, and unity/variety.

the last one: artificial selection/genetic engineering

plant breeding is modifying the genetic composition of the plant - but this isn't cloning (which is specifically introducing a gene into a genome). but you are artificially selecting for the phenotype that you want.

the second one is literally genetic engineering - the gene would have been cloned first and then inserted or genetically engineered into the new plant cell (the cotton).
