EngagementModerate engagement
Posts reference specific mechanisms like methylation states, horizontal gene transfer, and retroviral functions, demonstrating moderate to deep engagement with the science.
ImpactModerate impact
The discussions emphasize significant evolutionary implications, such as the role of viruses in mammal development, suggesting the article's ideas could influence broader scientific understanding.
Abstract in brief
The placenta is a specialized organ that evolved to support the developing fetus by facilitating the exchange of nutrients and waste between mother and young; it has independently evolved multiple times across different vertebrate classes, except birds.
As placentas and maternal systems become more closely linked, conflicts can arise, prompting adaptive changes in both mother and offspring, which has led to convergent evolution at various molecular levels in different species.
The review discusses the origins of placental structures in non-mammalian vertebrates, the evolution of mammalian placentas, and the mechanisms that have contributed to the diversity and complexity of placental forms in eutherian mammals.]
The evolution of the placenta in #poeciliid fishes.
Species in the livebearing #fish family #Poeciliidae have independently evolved placentas numerous times while retaining closely related non-placental sister species.

@ProTruth4Life The ancient Australian continent split from the rest of the landmass before the evolution of the placenta. That's why our mammals have pouches. Therefore, this is not a natural right in Australia.

This video explores the evolution of mammalian pregnancy and the origin of the placenta, highlighting its role in nutrient exchange and the adaptive changes that arose across vertebrate species, excluding birds.
Our study suggests that a unique extra-embryonic methylation state is a conserved feature of mammals – and therefore is likely to be important for the evolution of the placenta
@MakoSussyshima It's likely a function of the evolution of the placenta to accomidate the fairly large sizes of babies. Reptiles and more basal mammals like Marsupials and Monotremes all have cloacas which do all three.
If you have the time I bet your students would be amazed to learn a bit about horizontal gene transfer especially (of course) into animals. And/or a bit about human endogenous retroviruses, which might have something to do with the evolution of the placenta!

@jhumphre @DrPardi Yes, with best current evidence. But first eggs would have been soft and with the evolution of the placenta our branch of mammals would have stopped creating eggs entirely (females still produce ova, the unfertilized cells that grow into embryos).
Viruses can evolve alongside us! Endogenous retroviruses, incorporated into our DNA millions of years ago, may have helped drive the evolution of the placenta.

@jarlebreivik @Chris_Kamu @leroyb756 Mutations are random such as the accidental end-to-end fusion of human chromosome 2 and the evolution of the placenta from an accidental insertion of a virus' payload into a germ cell. Basically they are mistakes during the replication process and modulated by premature death.

@reluctantlyjoe I think a lot about the theory that retroviruses introduced the genetic material necessarily for the evolution of the placenta.
@ICRscience Mutations are random. They are all caused by mistakes made from DNA's error-prone replication system. Bad mistakes kill the offspring - ending that strain of mutation. Good mistakes allow propagation into new species such as the evolution of the placenta caused by a virus.
@TheHistoryGuy07 @AiG Yes it can. Random mutations often generate duplicates, triplicates or sometimes an entirely new chromosome. Other ways it can add information is with viruses - like the one that caused the evolution of the placenta.

However in placental mammals they’ve even been repurposed assisting in the evolution of the placenta.
The evolution of the placenta might not have been possible without it. “You could argue that without retroviruses you wouldn’t have mammals,” says Welkin Johnson, a virologist at Boston College. “It’s almost like life wouldn’t have evolved as it did.” https://t.co/Zka3AIuxhn
A gene from an ancient virus is responsible for the evolution of the placenta! “You could argue that without retroviruses you wouldn’t have mammals”. Amazing finding

Why it developed and is needed? Let's begin teaching basic biology in school again. You might be afraid of doing that.

@RisingDisciples @johngacinski Placenta’s offer an evolutionary advantage. Here’s an article on its evolution
The Evolution of the Placenta
R Michael Roberts, Jonathan A Green, and Laura C Schulz
@CarterAnthonyM @JNRutherford @AccretaResearch @placresearch @drjojames @IFPA_Official In an evolutionary context understanding the evolution of the placenta, almost always refers to the newly apposed maternal and fetal tissues. Not just innovations in the fetal membranes, but the new structure formed by the apposition of maternal/fetal tissues.
@EMERL9 Very conflicted. Like finding out you have lice that keep you from balding. But those lice are actually 8% of your DNA, and responsible for much of your development. Did you know the evolution of the placenta was driven by a ERV protein that fuses cell membranes?
@story_cosmos @DarecoGeorge Most of them are junk - meaning that they are so far mutilated from genetic drift that they lost their coding function. Some are still harmful. However, on a rare occassion, they can be hijacked to produce a beneficial mutation such as the evolution of the placenta.
@ardenking55 @GodDanC @pacmanx38 @AiG Yes, to a point, how important though are chance/ unexplainable events regarding how animals formed as opposed to natural selection? Like the evolution of the placenta in mammals is due to a random retrovirus. https://t.co/AMlfzaOtK8
