Tasty Challenge
This morning I woke up with a craving for Mexican Guacamole, made of AVOCADO. Then I remembered that scientists say that Avocados are an example of evolutionary anachronism, why? First correct answer gets a 10!! (without copy and paste!)
It is an evolutionary anachronism because: an anachronism means something that is not in its correct time, it most certainly belongs to an earlier time. In this case, the Avocado belongs to the cenozoic era. How the avocado still exists in nature after surviving its evolutionary failures remains a puzzle. An it's evolutionary because it has middly adapted to the environment, without changing too much.
It survived by animals that ate it and spread the seeds. It was not necessary to be a mammal to eat it, because the Avocado was attractive for its tast, colour and it's easy way to eat it (in one bite). That's how it was spreaded and it survived
This is because in the past, the avocado depended on his principal predator, so as the avocado could survive, through the seed that remained in its poop, but it is said that its main predator is extinted since a long time ago, thats why its a mystery how the avocado survive, because it should be extinted as his main predator. This kind of mysteries are evolutionary anachronisms. I apologize because of my english, i hope you understand. Mauricio Comesaña
Evolutonary anachronism is a term that envolves plants that evolved with animals that are now extintct. In the case of the avocado, they were fruits that needed the animals to spread, but not all the animals could eat the avocado and dont get damaged in the process(because of its enormous seed), the only ones that could eat it were the gomphotheres and the ground sloths, whose digestive tracts could soport the size of the fruit easily. obviously, those animals no longer exist and yet, avocados do.
Evolutionary anachronism refers to those fruit, flower, leaf and stem attributes that evolved as an interaction with animals that are now extinct. The avocado was eatten by large animals(whole). These animals, traveled long distances and defecated the avocado seed, which then, grow again. This means survival and growth via seed dispersal. But mammals disappeared 13,000 years ago in the Western Hemisphere. That was why a lot of fauna was lost. But even after this, the wild avocado still requires the same method of seed dispersal, which makes it an evolutionary anachronism.

The avocado is a fruit from a different time. The plant existed during the cenozoic era when megafauna, including mammoths and horses roamed across America. This frit attracted this large animals which ate it whole, travelled far distances and defecated it, leaving the seed to grow in a new place. But the great mammals disappeared forever about 13,000 years ago. But even after this major change in the land mammal population, the wild avocado still requires the same method of seed dispersal, which makes it and evolutionary anachronism. What makes the avocado even stranger as an example of evolutionary anachronism is that the pit is actually toxic. We do not have the liver or the enzyme systems to detoxifye our bodies from something like the avocado seed. But at the same time, the rhino which has been around for ages, can eat all kinds of things that are toxic to everyone else. How the avocado still exists in the wild after suviving its evolutionary failures remains a puzzle. But once man evolved to the point where it could cultivate the species, the fruit had the chance to survive.

Hi Andrea! Evolutionary anachronism it´s when a plant evolved in order to the species that eat it, but nowadays it´s extinct. Avocados were eaten by gomophotheres, that were one of the few that could support the digestion of it. By the way, this species is extinct, yet the avocado still exists. Despite of this fact, they could develop from animal´s excrement and the protection that trees provided them, and that´s why we can still eat this delicious fruit. P.s: I´m Agustina Castro and I don´t thing I´m going to eat avocado again...
For the avocado, gomphothere and ground sloths are still real possibilities. Pulp thieves like us reap the benefits. Hummans are able turn support the digestion of the avocado and will continue to mold the traits of the few species as it prefers. Ultimately, however, wild breeds will devolve less grandiose fruits, or else follow their animal partners, now humans, into extinction. As the humans are able to eat the avocado, it is still here, but it was not originally evolving for humans; because the gomophotheres were their first animal partners
But the great mammals desappeared forever about 13,000 years ago. But even after this major shift in the land mammal population, the wild avocado still requires the same method of seed dispersal, which makes it somewhat of an evolutionary anachronism.

The avocado is an example of evolutionary anachronism baecause the atrivute of fruits, attract megafauna (animals with a weight of 44kg or more)

ReplyDeleteThis fruit attracted these very large animals that would eat it whole, travel far distances and defecate it, leaving the seed to grow in a new place.

you can go on eating avocado because this is not how they got to our days... How did they do it?

ReplyDeleteThe avocado is an example of evolutionary anachronism because it is a fruit adapted for relationships with exinted large mammals.
