What is the racer method?
The R.A.C.E.R strategy is a method used to thoroughly answer a question. First, writers restate the question in a full sentence (R – RESTATE). Then, writers answerthe question in a brief statement (A – ANSWER). Next, writers must go back to the data and cites the evidence that best supports their answer (C – CITE).
What is the human race mean?
A race is a grouping of humans based on shared physical or social qualities into categories generally viewed as distinct by society. The term was first used to refer to speakers of a common language and then to denote national affiliations.
Are humans different races?
Humans have much genetic diversity, but the vast majority of this diversity reflects individual uniqueness and not race.
What race has the least genetic diversity?

Which race has the most Neanderthal DNA?
East Asians seem to have the most Neanderthal DNA in their genomes, followed by those of European ancestry. Africans, long thought to have no Neanderthal DNA, were recently found to have genes from the hominins comprising around 0.3 percent of their genome.
How much DNA do we share with bananas?
“Humans share 50% of our DNA with a banana.”
Do all humans share a common ancestor?
All living beings are in fact descendants of a unique ancestor commonly referred to as the last universal common ancestor (LUCA) of all life on Earth, according to modern evolutionary biology. Common descent is an effect of speciation, in which multiple species derive from a single ancestral population.
What is a female ancestor called?
Mitochondrial Eve, the most recent female-line common ancestor of all living people. “Y-chromosomal Adam”, the most recent male-line common ancestor of all living people.
Does every woman have the eve gene?

How many generations can genes be passed down?
According to calculations by geneticist Graham Coop of the University of California, Davis, you carry genes from fewer than half of your forebears from 11 generations back. Still, all the genes present in today’s human population can be traced to the people alive at the genetic isopoint.
