Evolutionary Structures; Homologous, Analogous, and Vestigial

I do apologize because I use the word flipper many times when I meant to say fin. One of the hazards of speaking to a camera. In this video you will learn about evolutionary structures which we use to compare organisms and their ancestors.

0:32 - Homologous
1:52 - Analogous
3:03 - Vestigial
Homologous - same ancestors, can have differing body parts
Analogous - different ancestors (probably), can have similar body parts
Vestigial - fading body parts like human tailbones from our ancestors who had tails

Great video, thank you! It's hard to find content in which the speaker speaks slowly enough for my students to understand and process the content without getting left behind. I did notice the fin/flipper stuff but thought "oh well, the rest is accurate."

I have studied Creation and the Theory of Evolution finding holes in both sides of the debate!

Homologous structures are proof of a common Designer.
Analogical structures again prove design.
Vestigual structures, there are no vestigual structures, the whale "hip bones" are used in mating they have nothing to do with walking.
The snake "legs" also used in mating.
The tail bone are anchor points for muscles that have to do with reproduction. Also if the tail bone was removed you would have to wear a colostomy bag, trust me it is needed.
