Embryology = Evolution = DNA???

Look at this picture of some embryos:

There's a person in here somewhere.

One of them is a human, do you know which?

How about this one:

This one is a bit more obvious?

Lets make it really easy for you:

Its right in front of you...

Do you know it now?

Even if you do I’ll give out the list of species from left to right:

Turtle – Hen – Ostrich – Dog – Bat – Rabbit – Human.

The Fish and Salamander to help complete the picture, compare the first embryo's to the rest.

What I’m trying to show you is that the earlier back you go through embryology, the harder it is to distinguish between animals. That is because we all come from the same origin, and I don’t just mean one egg and one sperm. I mean we all come from the same origin evolutionarily.

You can kind of see how as well. In embryology we all start out as a sort of tadpole, with a long tail, no arms or legs, and our eyes on the sides of our heads. As the embryo develops the tail starts to shrink or become more defined. Arms and legs start to appear as well as other obvious facial and bodily features. We would look something similar to a very odd and primitive amphibian. Finally, depending on what animal you are, you would start to take on the appearance of your true species.

Embryology is almost a documentation of evolution right before our eyes, albeit a rough one.


I want to link all of the last few posts on Evolution, DNA and Embryology together with the help of these images.

Evolution has developed all of us from a single cell to what we are now. This means that every animal on the planet is related to each other through that original one cell. This is provable.

Think about paternity testing. When you want to find out if a child is yours you give samples of your’s and the child’s DNA. Scientists then check for similarities and can therefore say whether or not you are the parent. The difference in DNA between each person is a fraction of a percent. So they check for that fraction.

It’s the same principle for seeing how related we are to other animals. Scientists took samples of DNA from all of the animals they could compare. When the results came back, a lot of people were surprised (as they always seem to be in Science).

What they found was that there is barely more of a difference between us and other animals than there is between us and our parents. Apparently it takes very little change to turn a turtle into a human.

In fact some people are now saying that the only real difference between us and chimps is in the section of DNA that doesn’t seem to make anything! – *Link to article*

In the end we are all just one big family. And Embryology shows us how close that is to the truth.

Hi 5!

Does this mean we should reconsider animal rights?

    When you know the evolution theory, it is good to know also the creation theory. Please view the God of Wonders video in my blog, jellybeanyee.wordpress.com It is a beautiful video very enjoyable to watch.

    • I’m all for balanced arguments and I’m letting this comment on here because I would hope that someone would do the same for me when I’m arguing against their theory. Besides it might make for some interesting discussion.

      But I do want to say that there is a huge amount of evidence for Evolution. The only thing that suggests Creation happened are religious texts. Those don’t count for evidence in the scientific community as they are not reliable (from a true historical point of view).
