The maximum rate of mammal evolution

“How fast can a mammal evolve from the size of a mouse to the size of an elephant? Achieving such a large transformation calls for major biological reorganization. Thus, the speed at which this occurs has important implications for extensive faunal changes, including adaptive radiations and recovery from mass extinctions. “
The Costs of Carnivory
journals.plos.org/plosbiology/...
“Our model provides insights into dietary changes and the evolution of body size in mammalian carnivores. Using a simple energetic model, we predicted that hunting costs and resulting energy requirements would increase with an increase in prey size.”
On the Rareness of Big, Fierce Animals: Speculations About the Body Sizes, Population Densities, and Geographic Ranges of Predatory Mammals and Large Carnivorous Dinosaurs
earth.geology.yale.edu/~ajs/19...
“Although some workers have suggested that tyrannosaurs and other large theropods were able to achieve huge size only by becoming sluggish carrion-eaters, an alternative explanation is presented here.”

+Andrew B (IrishRebel92) "There's a 10 percent loss of energy at each stage removed from plants" This statement would mean that at each stage it goes up from plants you lose only 10% of the total energy. so Plant (100%) to herbivore (90%) to carnivore (81%). In reality you lose 90% of energy so it goes from plant (100%) to herbivore (10%) to carnivore (1%) and if a carnivore eats another carnivore it only gets .1% of the energy in the plants

@jillianm8958 8 жыл бұрын

Reptiles have a completely different metabolic system than mammals. Reptiles can go much longer without food because they digest and use calories a lot slower than mammals because they're cold blooded unlike mammals. Most of mammals calories go toward maintaining the right body temperature. Since reptiles don't regulate their own body temp, their calories go farther and so they can grow to be much bigger while still not needing to eat as often as a mammal. Mammals need food every few hours or once a day to be healthy, reptiles can go days or weeks without food and be perfectly comfortable. Hope this helped

holy cow people... "vegetarian" and "herbivore" are NOT synonymous!! deer are herbivores, while a human that chooses to eat only fruits and veggies (by choice even though he or she can physically consume meat) is a vegetarian (or vegan if no animal products of any kind (like milk etc.) aren't consumed). Deer etc do on occasion eat meat, but they are not able to survive off of only meat, and do not have the proper stomach to process it, hence they are herbivores.

It's probably a matter of food availability. a giant carnivore would need a lot of meat, which means eating and hunting a lot of animals. Or, hunting equally large animals. There were plenty of huge carnivorous dinosaurs, afterall, but there were plenty of even bigger herbivores living at that time. Whales get fuckhuge, and they eat krill, which there's a near endless supply of in the ocean.

fatsamcastle You are taking my argument out of context, i am talking about humans. Natural predator carnivores don't breed animals and don't over populate the planet. Expecting all carnivores to be herbivores is not only impossible, but incredibly useless. We humans don't need meat or animal products to survive, we can thrive better on plants and it uses less resources. Unlike other carnivores we breed livestock for an increasing population. Since meat is already hard to produce land and resources wise it will only exponentially get worse if we continue this trend.

I have to agree with the energy expenditure idea over the physical limitation one when it comes to carnivore size. Looking at big cats, we can see that they have a very active method of hunting, so they're going to be burning energy to do it. Anything larger is going to rely on ambush tactics, like crocodiles or anacondas, or simply evolved to be hyper-efficient, like sharks. Both of which save energy compared to an intense chase followed by wrestling prey.

Even with humans the people that are "larger boned" only have bones that are maybe a few ounces, to a half pound or so bigger then other peoples bones. I saw the video on here about how people think big boned is a real thing when its not. Eating more only make you fatter, and maybe over thousands of years or more our animals today might adapt to become bigger once again, but more food does not make you larger.

short answer: because they can and need to be. longer answer: they need the size to house their large digestive tracts, the size also help fend off predators and since the don't have to chase down their food its always easy to get and they *allways* have a steady supply.

well actually it is pretty rare for animals to only eat meat or plants.most animals will eat a combo of both mainly animals we thing of as solely being plant eaters will actually eat bugs and sometimes small animals to gain what plants just won't give them.one good example of this is deer they will mainly eat grasses and shrubs but if they happen to come across say a bird or rabbit they will eat it.

Male polar bears average around 800-900lbs and are primarily carnivores. Granted not nearly the size of an elephant, but still something to consider, and as jsideproject mentioned whales and nearly all large sea creatures are carnivorous. Not that this theory holds to weight at all, but it should be seen as more of a guideline than a rule.

They were just comparing the stereotype (real men eat meat) to the animal kingdom. They weren't actually claiming the stereotype is true. However, I would say it is easier to get bigger with meat (I.e. The strongest man in the world), but at the same time it also increases the overall fat.

i´m a vegetarian since 1993 (23 years now) when younger i was jumping like a goat daily and there was no way to stop me (natural high , not induced) 4 years ago i stopped jumping , eating way much less since i didn´t need that much energy and in this 4 years i doubled my weight from 115lb to 225lb i eat only 1/3 of what I used to ... normal thyroid normal metabolism and no medicines that can cause me gain weight ... at a moment I started exercising again and lost 15lb in one month ... I got tired (i'm over 50 now) and I do not find any fun into exercising at all .. my quiet sedentary life all of the sudden turned a person that for 48 years never got up the 130lb limit to in 4 years get into a 225lb .. when the escalade started as I said , I was 115 pounds ... 48 years... i'm 5.9" tall ... I really do not see many big animals dancing the night away ...

@@allisondoak9425 Myself as an Alkarian, I feel the same way. Since the body heals much faster with chlorophyll and less metabolic acids have to be neutralized, I need less sleep. When I used to eat acidic meat and acidic sugar, I remember how tired I would feel a few hours afterward. Plants are energy and humans are biologically herbivores, that is why I feel sustained energy throughout the day. Those that behave more like omnivores and carnivores, will age much faster and have a shorter lifespan with medical problems.

Herbivores aren't vegetarians or vegans. Herbivores can only survive on a plant based diet. Vegetarians and Vegans are cabable for the most part of living off of pretty much anything edible by humans. They just chose not to. A reason for herbivores wasn't covered in this video that I think is pretty important. Survival. If you are built like a freakin tank and can take out a lion then it is clear that a lone elephant has a clear advantage over something smaller and less well built for defense. Size, whether large or small, has a clear defensive advantage.
