#Evolution

I started several Morning Glory vines this year, that recently started shooting up and twirling looking for something to climb. So I staked them, and observed that all five were turning anti clockwise.…

Hi. When a new species evolves, it is because of the enviormental pressure the species finds itself under when the enviorment changes, the population of the species moves to a new enviorment, or the competition from other species gets more intense.…

like if humans evolved gradually from earlier primates, there couldn't have been a single generation where a non-human suddenly gave birth to a human, right? so where do scientists/philosophers draw the line?…

I know that mammals decended from synapsids and reptiles are from sauropsids and that both of these came from amniotes. But it is popularly agreed that early amniotes were cold blooded, egg laying, scaly animals. So why can't amniotes=reptiles?…

I had the pleasure of meeting a very intelligent parrot. This parrot mocked how I moved and danced, it knew many phrases and the context to use them in.…

Hi! I have a question about genetic diversity seen as an ecological feature of the environment. Let me preface this by saying that although I have a BS in Biology, I now study something else. It remains something I am deeply interested in though!…

From an in press study that was published yesterday[ 1 ] on terrestrial mammals: ... Comparative genomics identifies 25 hearing-related genes showing rapid evolution, positive selection, lineage-specific mutations and coevolution with [relative vocal fold…

I just finished the dinosaurs documentary, and it was pretty amazing. I love dinosaurs and I'm also very interested in ancient humans and the creatures and ages came with them so I'm hoping to find something which can show me what happened after the end…

Pardon, I'm approaching this with little knowledge beyond the wiki page for symmetry in species. It says it's been suggested that either symmetry could've evolved from the other, but I'm wanting to know how/why you think/know radialism could evolve from…

I know I know probably very stupid but after thinking about it I got kind off confused so I need clarification • Race: a social construct but basically about physical appearance (mainly skin colour) of a person and what part of the earth they’re from but…

"From so simple a beginning..." What morphologies are more likely to appear during evolution is a central question in zoology. Here we offer a novel approach to this question based on first developmental principles.…

As far as I know, no fossil ape species has yet been found which managed this. Human infants are sometimes born with a small tail, but this is just a vestige of the embryonic tail not disappearing correctly, it is not a true, bony tail.…

Of course many exceptions but these are general rules submitted by /u/LisanneFroonKrisK [link] [comments]

Is scolopax minor the American Woodcock only in the scolopax genus due to convergent evolution with scolopax rusticola and other Eurasian species?…

Published today, in press: Jenkins X, Peecook B, Choiniere J ... The phylogenetic origin of turtles Current Biology, 2026 https://doi.org/10.1016/j.cub.2026.04.070 The evolutionary origins of turtles remain poorly understood.…

like say ants who live in colonies versus spiders who tend to be solitary submitted by /u/Massive_Fisherman231 [link] [comments]

Would've included amphibians too but caecilians exist lol. There are countless lepidosaurs that evolved to have no limbs, and this condition has independently evolved within this group multiple times (rather than evolving just once and the trait being…

[Revised entry by Roberta L. Millstein on May 27, 2026. Changes to: Main text, Bibliography] Evolution in its contemporary meaning in biology typically refers to the changes in the proportions of biological types in a population over time (see the entries…
