I mean, water buffalos eat grass. It seems like there is an endless supply of energy and nutrition for them because we find grass wherever we look. If an individual buffalo is a little bigger and stronger than the majority, lions will hunt someone weaker, and the size of buffalos will continue to grow even bigger through evolution. And why isn't the same happening with antelopes making them even faster? Are their possible speeds already maxed out? Maybe faster antelopes injure themselves from the enormous forces their bones have to go through while running? submitted by /u/Optimal_Leek_3668 ..read more

Just finished t sci fi movie Voyagers. In the movie they sent out 30 individuals on a generation ship to colonize a new planet. I don’t know enough about evolution to say for sure, but 15 breeding pairs seems too low. How many breeding pairs of humans would you need to repopulate the species? submitted by /u/Lovebeingadad54321 [visit reddit] [comments ..read more

I have wondered for a while now, why do humans go through menopause and how did we start going through it? Its a really unique feature that very few animals have. submitted by /u/DieselDeletus_ [visit reddit] [comments ..read more

(Just found this out today) One of the few venomous mammals, and the only venomous primate, the Slow Loris evolved to produce venom through modified sweat glands unlike most other venomous (Vertebrate) animals which have modified salivary glands. They lick their armpits where the sweat glands are and coat their teeth with it. submitted by /u/DieselDeletus_ [visit reddit] [comments ..read more

The balance organ in the inner ear consists of three semicircular canals. This structure is remarkably strongly preserved all the way from sharks to humans, so must have a strong survival value. When did it evolve? (And how?) submitted by /u/Turbulent-Name-8349 [visit reddit] [comments ..read more

Why would animals like camels, penguins, or any complex lifeform adapt as they have to live in such hostile environments (e.g. adapting to thrive on little water for the camel and extra layers of fat for the penguin). Especially since the world was more connected with Pangea, why and how did this natural selection occur instead of migration to more habitable environs? If you could explain like I'm five, that would be great. I grew up in YEC circles and am trying to learn about evolution (as opposed to the creationist strawman version) for the first time. Thanks! submitted by /u/pickle_p_fidd ..read more

Im learning about Ediacaran fauna right now and I just wanted to ask if my assumption that the evolution of eyes in bilaterals is the cause of the Cambrian explosion. Seems like Cambrian explosion is mostly about animals. Maybe new animals created new niches for plants or whatever, but I’m not really seeing an explosion in the Cambrian of flora much. So was it sight that caused the explosion? In my mind, after reading and watching a bunch of material about this, it seems like some worm about 540 million years ago got a pair of eyes, and that animal is the cause of the Cambrian explosion and a ..read more

It seems like a high % of mothers today are unable to, due to problems latching, milk supply, pain, etc. Has evolution optimized for breastfeeding? It would seem to be as basic of a survival need as drinking water, eating, sleeping, etc. submitted by /u/Rcrez [visit reddit] [comments ..read more
