“The role of science in defining


personal identity cannot be


over emphasized.”

“Science transcends national,
cultural, or institutional
boundaries and thereby is a
shared activity of humanity
at large.”

DNA TELLS US WHO WE ARE

(WE ARE ALL AFRICAN!)



HOW KNOWLEDGE OF DNA MAY IMPACT OUR LIVES

DNA
: double helix of nucleic acids that are usually the

molecular basis of heredity

944 Origin:
d
eoxyribo
n
ucleic
a
cid = DNA

Gene
: a specific sequence of nucleotides in DNA

located usually on a chromosome and that is the

functional unit of inheritance of one or more traits

Genome:

broadly speaking the genetic material of
an organism


Human Chromosomes:
rod
-
shaped DNA
-
containing

structures in the cell nucleus that contain most of the genes

Humans have 23 pairs

Venter was first to publish the genome of a


living species and the first to publish the human


genome.




Venter was the first to create synthetic


bacteria with DNA designed on a computer.

"WE ARE ALL AFRICAN!

Can scientific proof of our commonality save us?”

[By reducing divisive identity differences]

Fossils, climate, and artifacts indicate

that we all descended from a small group

of homo sapiens living in central
-
eastern

Africa .


DNA evidence from living humans is even

more compelling that we are all African.

HOMO HOMO HOMO


FLORESIENSIS NEADERTHALENSIS SAPIENS

As recently as 30,000 years ago, we lived

with two other hominins on this planet.


DNA from Neanderthal bone fragments show


evidence that Humans and Neanderthals interbred.


Neanderthal and Modern Human DNA is 99.7%


identical.


4 % of Asians’ and Europeans’ DNA may be from


Neanderthal ancestors.

Sahelanthropus Modern


Tchadensis Chimpanzee

Latest estimate:


6 to 7 million years ago Sahelanthropus tchadensis

marked the point when our ancestors and

Chimpanzee ancestors split from a common lineage.

Modern Chimpanzee DNA is 98.8%

Identical to modern human DNA.

“Chimeras of human and mouse cells are

now constructed in the laboratory as a matter

of course.”


“What if we were to fashion a chimera of 50%

human and 50% chimpanzee cells and grow it

to adulthood? That would change everything.”

Marcus Wohlsen

“…tinkerers and hobbyists …will soon be able to
perform sophisticated feats of genetic
engineering at home.”

“Their goal: to make a creature that no one has

ever quite seen before in nature. Also, to make

a creature cooler than anyone else’s.”

“The plummeting price for sequencing DNA has

long fueled predictions that everyone’s medical

record will soon include a copy of his or her

genome.”

“The question is not so much as to how to

engineer [life] but what to engineer.”

We can use the contents of people’s genomes to

administer better and more accurate health care.
