Northern Tanzania and the Afar region of Ethiopia have yielded some of the most famous and informative glimpses into hominin evolution. All of the following are true about fossil finds in these areas EXCEPT thatthe Laetoli site in northern Tanzania yielded a series of fossilized footprints.→although the fossils from these two regions were deposited half a million years apart, their many resemblances justify including them all as part of the same species, Homo habilis. Lucy, a tiny hominin female who lived around 3 m. y.a., was found in the Hadar site in the Afar region of Ethiopia. the fossils from both Laetoli and Hadar forced a reinterpretation of the early hominin record, suggesting that hominins are much closer to apes than previously known. the fossils from both Laetoli and Hadar are representative of Au. afarensis.

Although the fossils from these two regions were deposited half a million years apart, their many resemblances justify including them all as part of the same species, Homo habilis.

Explanation:

The Afar region of Ethiopia is known for having provided the world´s oldest uncontested hominine, the Ardipithecus kadabba, which is believed to be 5.5 million years old.

On the other hand, fossils discovered in Northern Tanzania proved that there were at least two Australopithecus species and that the Australopithecus line wasn´t really affiliated to the Homo line. Furthermore, Australopithecus and Homo species existed next to each other for around one million years.

explanation:

allergens: overstimulate the nerve system

neurotics: attack nerve cells

mutagens: damage or otherwise alter dna sequence

generators: cause defects during growth and development  

carcinogens: cause unchecked cell growth

i hope you get the idea according to me these are the effects that happened.

well, i can't read it so i'll ask you questions about it : )

if you were a reader and you read the introduction, would you want to read more?

does it start with a question? if so, is it something you would want to read about?

and ask any friends or family for their opinion : )
