Hi brainiacs, does anyone know: what preceded the sarcopterygians in evolution? Is it the spiny fish? What came before them? Can humans be traced back to a stage where they reproduced asexually? submitted by /u/National_Rain5002 [visit reddit] [comments ..read more

I am endlessly confused on how phylogenic trees are made. I have to make some for a class I'm in but everytime I think i figure it out, I get confused again. Does anyone have any tips for making phylogenic tree? I have 7 species and 30 nucleotides to organize but it seems that the traits don't match up with how similar the organisms are. submitted by /u/Ok-Consideration7949 [visit reddit] [comments ..read more

Page 2 of Why Evolution is True. Darwin had his own answer to the conundrum of design. A keen naturalist, who originally studied to be a minister at Cambridge University(where, ironically, he occupied Paley’s former rooms), Darwin well knewthe seductive power of arguments like Paley’s. The more one learns aboutplants and animals, the more one marvels at how well their designs fittheir ways of life. What could be more natural than inferring that thisfit reflects conscious design? Yet Darwin looked beyond the obvious,suggesting—and supporting with copious evidence—two ideas that forever dispel ..read more

I was thinking earlier about what effect having predation of eggs has on a large breeding population as far as through an evolutionary scope. I really don't have all the science details to call it but I feel/think there is something there as far as co-contributing to other species evolution... submitted by /u/Particular_Cellist25 [visit reddit] [comments ..read more

Hi! I am doing some research for a project and can't seem to get clear answers for a few things, so I figured I would ask them here... Is there a specific hypothesis about mate choice that is more widely accepted? Are any largely disregarded? Going off of that, am I missing any of the major hypotheses? I've been looking mainly at the good genes theory, sexy sons, and sensory bias. Where does runaway selection fall into all of this? Are Bateman's principle and the handicap principle as controversial as my preliminary search results have made them seem? Thank you! submitted by /u/cruthkaye [vi ..read more

So there’s this overwhelming question called the Fermi Paradox which ask the question. “Where is everybody?” Everybody being of course aliens. Our planet isn’t one of the oldest, it isn’t unique since there are other planets with the same capability to cradle life but where are they. I have a theory that these advance civilization suffered with the greatest problem known to man. Natural selection, Where traits most Ideal is left to the progeny. My theory is the species are wiped out by natural selection through A. Genetically Terrible where people are genetically used to violence and commits ..read more

Humans, along with some primates and some bats, possess MS while others don't, why? And why is MS so painful in humans as compared to other (is it just a pain tolerance threshold of humans and other primates?) submitted by /u/Coc_Alexander [visit reddit] [comments ..read more

Hello guys, I would like recommandation from you. I’m just a guy really fascinated by evolution and that love to read. But the only book i read about it so far is Dawkins selfish gènes years ago. Thought I reread it again 2 years after. And now I like… want to know more ? Learn more ? Discover what is up to date cause selfish genes still is an « old » book. Do you have recommandation? Remember i don’t study biology or something im an IT guy I just love knowledge and since so many people around me doesn’t believe in evolution, knowing a little better allow me to explain to them. Thanks submit ..read more
