Humans evolved from a common ancestor they 

have with apes.   Evidence exists in our amino 

acids.   We share 95% of our amino acids with 

the Rhesus monkey.   Chickens, frogs, and 

lampreys share less with us in that order, which 

makes sense, considering frogs and chickens are 

newer animals whereas lampreys are early 

animals.

Humans and apes only differ in chromosome 

number by one, which is accounted for by our 

second chromosome, which is two 

chromosomes fused together (shown by it 

having two centromeres and an extra 

telomere).   Most of our chromosomes are 

identical to those found in at least one other 

ape.   Any differences in our completely unique 

chromosomes are explained by inversions and 

translocations.

Humans are still evolving today.   Some say our 

technology and medicine have stopped 

evolution, but this is not the case.

In the past 5000 years, the human brain has 

shrunk from 1500 cubic centimeters to 1350 

cubic centimeters, or about 10%.   This may be 

due to our ability to rely on each other and 

specialize, thus not needing all of our brain.

Sickle cell anemia causes red blood cells to be 

sickle shaped, thus impairing blood flow, but 

also preventing malaria from infecting the 

cells.   This evolved in the past 3000-4000 

years, and has affected 10-15% of the people 

in Africa and India-Pakistan.

Most people cannot digest lactose.   7500 years 

ago, European humans gained the ability to 

digest it, taking advantage of a new food 

source.

When our ancestors first left Africa, they ware 

all dark-skinned.   Humans in the northern 

parts of the world evolved to have lighter skin 

color, as there was not as much sunlight, so 

there was not as much of a risk for skin cancer, 

but they needed to be able to absorb vitamin D 

better.   Blond, blue-eyed people are also 

newer, as they were better off in these less 

sunny areas but were not as well of near the 

equator.

When Europeans developed agricultural 

societies, new diseases were introduced.   The 

Europeans soon developed genetic resistances 

to these diseases, but Native Americans had 

none of these, so when Europeans migrated 

across the ocean, the Native Americans were 

decimated by these diseases.   The evolution of 

resistances shows our ability to evolve.

As final thoughts, I believe evolution is true.  

Fossil records show apelike hominids existed in 

the past who had similar bone structures to us.  

The similarities in the chromosome numbers 

and structure are too significant to ignore.  

Believers of intelligent design can say they 

cannot be proven wrong conclusively, but that 

is not a scientific way of looking at things.  

Also, the Bible is not a viable source.   The 

overwhelming evidence for mankind's 

evolution is too much to ignore, and it must be 

accepted.
