DNA: Comparing Humans and Chimps

The chimpanzee and another ape, the bonobo, are humans' closest living relatives. These three species look alike in many ways, both in body and behavior. But for a clear understanding of how closely they are related, scientists compare their DNA, an essential molecule that's the instruction manual for building each species. Humans and chimps share a surprising 98.8 percent of their DNA. How can we be so similar--and yet so different?

So Much Alike...

Human and chimp DNA is so similar because the two species are so closely related. Humans, chimps and bonobos descended from a single ancestor species that lived six or seven million years ago. As humans and chimps gradually evolved from a common ancestor, their DNA, passed from generation to generation, changed too. In fact, many of these DNA changes led to differences between human and chimp appearance and behavior.

Banding Patterns

Examine the Evidence

Matching DNA? Human and chimp DNA is nearly identical when you compare the bands on chromosomes, the bundles of DNA inside nearly every cell. Which two chromosomes are more alike?

Banding Patterns

The light and dark bands on these chromosomes, created by a laboratory dye, reveal similarities and differences among human, chimp and mouse DNA.

Human and chimp X chromosomes both contain about 1,100 different genes, or sets of instructions. Each gene affects a particular trait in the body.

 CPX - facial development, cleft palate
 SMC1L1 - chromosome maintenance
 OPN1LW - red color vision

Seeing Red

Most genes in humans and chimps are nearly identical. Both species have the OPN1LW gene, which allows them both to see the color red. But mice lack OPN1LW--and have trouble seeing red.

... And Yet So Different

If human and chimp DNA is 98.8 percent the same, why are we so different? Numbers tell part of the story. Each human cell contains roughly three billion base pairs, or bits of information. Just 1.2 percent of that equals about 35 million differences. Some of these have a big impact, others don't. And even two identical stretches of DNA can work differently--they can be "turned on" in different amounts, in different places or at different times.

Same Genes, Behaving Differently

Although humans and chimps have many identical genes, they often use them in different ways. A gene's activity, or expression, can be turned up or down like the volume on a radio. So the same gene can be turned up high in humans, but very low in chimps.

The same genes are expressed in the same brain regions in human, chimp and gorilla, but in different amounts. Thousands of differences like these affect brain development and function, and help explain why the human brain is larger and smarter.

Slightly Different Genes

The chimpanzee immune system is surprisingly similar to ours--most viruses that cause diseases like AIDS and hepatitis can infect chimpanzees too. But chimps don't get infected by the malaria parasite Plasmodium falciparum, which a mosquito can transmit through its bite into human blood. A small DNA difference makes human red blood cells vulnerable to this parasite, while chimp blood cells are resistant.

Flank_Attacks,

Jesus freaking Christ. I’m trying to intimidate you by asking reasonable questions?? I’m presenting to you just some of the scientific evidence that humans and chimpanzees have a common anscenstor, and I’m asking you to explain them.

 

So let’s recap. You accused me of dodging your question, that I didn’t see. I then answer your question, and then ask you questions of my own. Your response? That I’m trying to “intimidate” you by asking questions. Humans and chimpanzees share more than 98% the same DNA. Every scientific source you pull up will confirm this, just as the one Senior posted does. If that number is wrong, then what is the right number? What is your source?

 

Typing ‘facts’ instead facts, doesn’t make them cease being facts. Just like typing ‘paratrooper’ instead of paratrooper, doesn’t make me cease being a paratrooper stationed at Fort Bragg, NC who is on jump status and regularly jumps the MC-6 parachute. If you think I’m lying about that, man up make your accusation. Don’t be cowardly about it by weakly implying it, putting semi-quotes around paratrooper. 

 

👊

'Senior' L-L' .. Continuing, to throw around, Very Large numbers

We KNOW these numbers are very large. It's just a matter of estimating the number of organisms in the world, and the time they have been around. I didn't pick "quintillions" very carefully - it's a huge number by normal standards, but in terms of the scope of life on Earth, it is rather small! There are several nonillion bacteria alive right now. One nonillion is a trillion quintillions.

But for the evolution of a modest sized branch of large organisms, there are smaller numbers of smallest changes in DNA.  This is why in such a branch, there is not a huge amount of variation (eg the large commonality between chimp and human DNA).

" If evolution drew on some separate source of information we could see the effects of this in the way it affected changes over time."

will you elaborate please?

No, it’s ACTUALLY backed by science.  You can disbelieve the science all you want but it’s still science. 

The disbelief in JC being supernatural is as “amazing”  as the disbelief in Mohammed, Thor, Brahma, etc. being real deities.  There is an equal amount of evidence for all of them. 

 I brought up your overuse of punctuation not as an argument for the topic, but rather to point out it’s annoying. 

 

 

I don't think there has been any claim that Mohammad is a deity ... at least, yours is the first I have ever seen (and it is a claim in the negative, I guess).  According to Islamists, Mohammad is considered a prophet.

 

A single claim is actually evidence.  As for "scientific evidence" .... that is another story.  What scientists accept as evidence changes from time to time.  What was science before is not necessarily science now.  The future of science is yet to be written.

Interesting.I remember a saying about There is sky above the sky.

And there are seven heavens.If we are allowed to reach second heaven.

 I believe it’s time travel forward yes, backward no.  Intuitively it seems like teleportation would be impossible, but I dare not say no with as weird as quantum mechanics gets.

Teleportation could be used to explore distant galaxies and universe.

Why would creationists attack Bill Nye?  I understand attacking his interpretation of things, and even attacking his ideas, but why would they attack him?

A few years back, Bill Nye had a rather well-publicized debate with Ken Ham, about Evolution, and the age of the Universe.

I thought both presented their cases well. But the general consensus was Nye won convincingy.

Creationists have been painting bulls eyes on him ever since.
