Evolution Questions

2010



Student Questions

Last week you shared your evolution

questions with me. They were very good, and

while Id like to attempt to answer all of them,

Ive had to narrow them down to just a few.



What about females?

In the Journey of Man, female linage tracingwas virtually ignored. Can female lineages betraced with DNA markers too?

Yes, they certainly can, and have been forsome time.

Matrimonial lineages are traced with

mitochondrial DNA because virtually all of azygotes mitochondria are inherited from thefemale (mother). Search:Mitochondrial Eve



Mitochondria Supply Cells with Energy

and They Contain mt-DNA



Different Patterns of DNA Inheritance



Hypothetical mt-DNA Linage

Emerges Over Time.

What About God?

Several questions focused on this topic.

A very good, balanced presentation can be

viewed onYoutube. It is part of the Evolution

series that you are familiar with.

Heres the link:

Geography Question

Why is there so much uncertainty on why

humans are found everywhere when we know

that Pangaea existed? Couldnt our ancestors

have been living in Pangaea, and as a result,

they would naturally be spread over all of

todays continents?



Could Humans Have lived on Pangaea?

Humans (Homo sapiens) are a relatively new

species (less than one million years old). Lets look at this animation from the

Smithsonian. What did the world map look

like 1-10 million years ago?
