Question

Will give medal!
Scientific evidence indicates that Homo erectus were the first hominids to leave Africa. Which of the following would make this conclusion incorrect?
A. DNA analysis showing Homo erectus and modern humans did not have a common evolutionary ancestor
B. An archaeological dig finding fossil remains of Australopithecus Africanus in Europe and Asia
C. Finding tools used by Homo erectus in continents other than Africa
D. A discovery of fossils of Homo erectus showing that they walked upright

Answer 1

Which do you think is the answer and why?

Answer 2

Well two answers out of the 4 makes the most sense. But a big hint is that A is eliminated off the bat.

Answer 3

DNA analysis showing H. erectus and modern humans did not have a common evolutionary ancestor

An archaeological dig finding fossil remains of A. africanus in Europe and Asia

Finding tools used by H. erectus in continents other than Africa

A discovery of fossils of H. erectus showing that they walked upright

Answer 4

Australopithecus afarensis had a longer skull than Homo neaderthalensis and was the first hominid to create tools.

Australopithecus afarensis had a more pronounced nose than Homo neanderthalensis, suited to breathing cold air.

Homo neaderthalensis was taller than Australopithecus afarensis and was able to walk upright first.

Homo neaderthalensis had a larger cranial capacity than Australopithecus afarensis and had a larger brain.

Answer 5

The number of DNA mutations in an organism is measured over time to determine how long it will take for a new species to evolve.

The number of DNA mutations in a species is compared to the number of DNA mutations in another species to determine the relative amount of time each species has been evolving.

The number of differences in a specific DNA sequence of two species is multiplied by a known mutation rate to determine the number of years of evolution that separate the two species.

The number of differences in the DNA sequences of two organisms of the same species is averaged to determine how many years of evolution have occurred.
