According to this evolutionary tree, when did the human lineage branch away from the other great apes?

7-8 MYA.

Organisms, such as hominins, that walk on two legs are said to be

Bipedal.

Homo neanderthalensis lived from about 28-300 tya and are believed to have evolved in

Europe and/or Asia.

Homo sapiens, Homo neanderthalensis, and Homo erectus all belong to which of the following categories of the Linnaean hierarchy?

Genus.

The unique, two-word Latin or scientific name given to each organism is a combination of the organism's ________ and ________ in the Linnaean hierarchy.

Genus; Species

The organisms in the human branch of the ape family are called

Hominins.

Archaic Homo sapiens originated about 300-400 TYA and had features intermediate between those of ________ and anatomically modern Homo sapiens.

Homo Erectus.

Examine the following Hominin evolutionary tree. Which of the following genera most likely comingled with modern humans?

Homo neanderthalensis, Homo heidelbergensis, and maybe Homo floresiensis.

Which of the following categories of the Linnaean hierarchy would include the broadest range of related organisms?

Kingdom.

Nuclear or genomic DNA is passed down from ________ to all their offspring.

Mothers and Fathers.

Mitochondrial DNA is passed down from ________ to all their offspring.

Mothers.

Thumbs that can be touched to each of the other four fingers are called ________ thumbs.

Opposable.

The idea that modern humans first evolved in Africa about 195,000-200,000 years ago and eventually spread into other continents is known as the ________ hypothesis.

Out-of-Africa.

In the Linnaean hierarchy, closely related classes are grouped together into a

Phylum.

Which of the following categories of the Linnaean hierarchy would include the most closely related organisms?

Species.

If DNA from a son and his dad are compared, which of the following would be the likely result?

The son's genomic DNA would be at least a 50 percent match to his dad's genomic DNA, and there would be no match in the mitochondrial DNA.

If your mitochondrial DNA was sequenced and compared to the sequence of mitochondrial DNA isolated from your mother's maternal grandmother (the mother of your mom's mom) would you expect to see a significant match to yours and why?

Yes, there would be a significant match because I inherited my mitochondrial DNA from my mom who inherited it from her mom who inherited it from her mom.
