Both have the same isekai themed anime where it involves an entire group of students whom were drafted to fight the biggest evil or at least that was the plan of those who summon them, it also involve one outcast to be left out and that outcast becoming better than his weaker self...in also involves then weak outcast having a harem.  

- Both main characters are weak and bullied by their follow classmates at the beginning - Both ends up in a pinch right at the beginning of the story - Both develops "OP" powers/skills from surviving their unique environment - Both develops a harem of females (and even both have loli-like characters) - Both main characters falls in love with the other Heroine they first meet. - Both ends up fighting against evil that plots something against their classmates at the "late game" of the show. - Both are anti-hero and hero at the same time. - Both never wanted the OP cheat power they obtained/earned and just wanted to be "ordinary". - Both have weird and unique characters that makes the story interesting - Both have a second season (with Arifureta having even a 3rd upcoming season and Shinka no Mi having a upcoming 2nd season) read more 

Both male protagonist and his class transported to a video game world with fantasy and magic. Male protagonist sets out on a solo journey and meets female side-kicks, basically kick starting a harem. 

Both of the main characters in each anime are bullied in their previous world before being teleported with their class. Both involve the main character becoming extremely powerful in a short amount of time overcoming a challenge which would be something that would be pursued only by the strongest. If you liked Shinka no Mi then you would most likely enjoy Arifureta as I think it is just a superior version with practically the same plot just with different beginnings.  

Nearly the exact same story in both anime. In both the Mc ,along with his whole class is transported to another world. Both Mc go from weak and helpless to awesomely overpowered. "Arifrueta" does have a darker kind of them than "The Fruit of Evolution" though 

Both Isekai Both have op mc Both mc eat monster meat/strange fruits and get stronger skill Mc get bullied, betray and etc by classmate . Mc still have friend that care for him . Try watch shinka no mi and you will notice the similarity between this 2 .  

These two are very similar. Both have a male MC that starts off weak, but then become OP from eating strange things. Both involve a group of normal students being teleported to a fantasy world and gaining powers. 

- Both are Isekai anime and from a video game fantasy world - The MC was kicked because he was weak - Builds a harem of girls - Both MCs become OP 

Both MC's get reincarnated to another unknown world where they develop over powered skills. (and also cute girls) 

Both MCs are OP Both MCs start alone Both MCs get a harem Both are Fantasy Isekai anime 

Even if these anime don't have exactly the same genre their storyline has somewhat similar setting. Getting the whole class isekaied, strong lead MC. Gaining xp, defeating monsters and a lot more similarities. The difference is spider has a little dark theme and fruit of evolution has happy and harem + ecchi theme. The spider has female lead and the other has male lead. Other than that Both of them are a good watch
