Speculative biology is simultaneously a science and form of art in which one speculates on the possibilities of life and evolution. What could the world look like if dinosaurs had never gone extinct? What could alien lifeforms look like? What kinds of plants and animals might exist in the far future? These questions and more are tackled by speculative biologists, and the Speculative Evolution welcomes all relevant ideas, inquiries, and world-building projects alike.

This topic is for the descussion of what Mammals would be like if they Never developed Pariental care.

Here are some things we can figuer out:

What are the Mammalian milk glands going to be used for?

How would this effect Mammalian developement and dominance?

How would this change other features of Mammals?

How will this effect Mammalian behavior?

How will this effect other groups?

Along with any other differences that you can think of happening.

I also Have some Ideas already but I would like to hear your thoughts before I post them.

Any way Please post, comment and share ideas please.

The milk glands would never have developed. Marsupials would never have evolved pouches. I might be stretching it, but I doubt mammels would have ever gotten to be large without some sort of parental care. Take mice or rabbits. Their young are totally defenseless. Easy meal for carnivores.

It would have all to do with the mammary glands I think. The whole point of being a mammal is to have mammary glands. They would need to evolve for an entirely different purpose early on in mammal evolution. It's likely parental care evolved earlier than the development of mammary glands. If mammary glands evolved as a result of parental care, removing parental care greatly reduces the chances of mammary glands ever evolving. Something similar may evolve for a different purpose (For who-knows what purpose), but the bearers of those organs would not be mammals.

Among other things, muscular lips wouldn't evolve. And, without parental care, they'd be pretty much like reptiles, fending by themselves since birth, meaning they would occupy many ecological niches across their lifetime. Consequently, there would be far less species.

We certiantly wouldn't be around, I don't think any really intelligent mammals would exist without parents teaching them what they know.

I was thinking pack hunting could evolve from females offering Milk to males inorder to make them hunt for her?

The other use of Milk was as an offering to a seperate species Kinda like how Aphids are protected by Ants?

Also Mammals would need to be born more developed in some species.

The lip thing would not be a common feature but instead develope in males of certain species and the previously mentioned symbiotes.

Also I still think Mammals would be simular to ours since fur, skulls and stance would devolope along simular lines.

I'm happy that I finnaly made a good topic.

Also please keep posting. Some of the above answeres were generated thanks to your posts and are very helpful.

the aphid idea sounds pretty cool, i imagine round, soft, fuzzy critters being cared for by possibly... dinosaurs? them terrestrial toothed birds that we all love... they'd still have the parenting dealy going for them and that would certainly help them go along with taking care of another species.
Oh Fine.

Oh hi you! Why don't you go check out the finery that is SGP??

That opens interesting possibillities like Mammals having Birds and Non-Mammal species taking care of thier young instead of their parents.

Could that allow burrowing Dinosaurs(and could that cuase them to survive the K-T)?

Not nescisarily what about the things that were said about how milk glands might still be used?

And if you think that then try to think of a way these new Mammals can equate to more than Reptiles with fur.

They would be furry reptiles. The only thing that separated early mammals and lizards was parental care. It lead to the development of mammary glands, and social behavior, and communication, and emotion, and intelligence. It would probably end up being birds that become the dominant species.
We should all aspire to die surrounded by our dearest friends. Just like Julius Caesar.

"The Lord Universe said: 'The same fate I have given to all things from stones to stars, that one day they shall become naught but memories aloft upon the winds of time. From dust all was born, and to dust all shall return.' He then looked upon His greatest creation, life, and pitied them, for unlike stars and stones they would soon learn of this fate and despair in the futility of their own existence. And so the Lord Universe decided to give life two gifts to save them from this despair. The first of these gifts was the soul, that life might more readily accept their fate, and the second was fear, that they might in time learn to avoid it altogether." - Excerpt from a Chanagwan creation myth, Legends and Folklore of the Planet Ghar, collected and published by Yieju Bai'an, explorer from the Celestial Commonwealth of Qonming

Well not reptile as much as primitive synapsids, maybe they would look kind of like modern monotremes except without the parental care.

I think fossilized burrows of Hypsilophodont have been discovered so dinosaurs where already burrowing.

Please, flightless birds are a joke. Mammals, being endothermic, would end up dominant, parental care or not

I never said flightless birds. I just meant birds in general would end up being more intelligent and thus more dominant.
