It's worth a read on the protein involved, it's amazing that we've a piece of viral material that is responsible for mammalian life.

This is where virii come from. A piece of material in one form of life entering another form and disrupting normal, healthy mechanisms.

This gets deep into evolutionary biology, but basically mammals most probably evolved from egg laying creatures, and at some point the original yolk sac was converted into the placenta, and the previously externally laid eggs were retained inside the body instead of being shot out.

The viral transfection probably kicked off this evolutionary step. Must have been weird for that first egg layer having their eggs parasitize their body.

About mammalian yolk sacs...

β€œEvolved” haha take your fairy tales elsewhere

Downvoting is more effective to suppress the truth behind evolution rather than actually debating the topic, apparently.

Evolution is about how life came to be diverse. Not how it came to be.

If you want to be ignorant that is fine, but you can't deny a giraffe's 7 foot laryngeal nerve, endogenous retroviral DNA, ring species, atavisms, etc. There is vastly more evidence for evolution than the little bit you ignored in high school.

What are you talking about? There are 6 definitions of evolution:

Cosmic evolution: the origin of time, space, and matter from nothing in the β€œbig bang” Chemical evolution: all elements β€œevolved” from hydrogen Stellar evolution: stars and planets formed from gas clouds Organic evolution: life begins from inanimate matter Macro-evolution: animals and plants change from one type into another Micro-evolution: variations form within the β€œkind”

Show me any evidence of any evolution other than micro. Listing similarities in animals is not evidence of them coming from common ancestry. https://world.wng.org/2017/03/jumping_genes_further_debunk_evolution

Come on. Some bacteria decided to one day grow lungs and fuck on the beach instead of in water... The fact people believe this is laughable but it shows the power of public schooling and the religion of science.....shit hasn't been proven or demonstrated how one thing can turn to another by chance and most of the world including the RC Church take it as fact.

I had a Based Biology teacher in high school like 20 years ago, he was like "We all know the truth but this is what the curriculum says we have to teach".

I’m still stuck on bacteria forming from acid rain on lifeless rocks. It requires oxygen to live but any oxygen in the air oxidizes the amino acids long before anything meaningful can arise. They’ve tried to test their theory already, you simultaneously need no oxygen for the acids to form without being oxidized under the extreme conditions, but also need the oxygen for it to survive once formed. Evolutionary theory is riddled with contradictions like this, so just focus on the first one they make. I guess that could be saying that everything came from nothing in the Big Bang, but most don’t care about that contradiction IME.

β€œIn the beginning God...” is a less religious phrase than β€œin the beginning rocks...”

Are dogs and wolves the same animal?
