Then consider that plants have a symbiotic relationship with animals.
And think about the size of Avocados (for example), and in particular the seed in the middle. Birds aren't going to distribute them...
- greggsy 4y agoI’ve read that sloths we’re responsible for spreading avocado seeds, but it makes me wonder whether those seeds were always that large?
- DrBazza 4y agoYes. I used avocados as an example because everyone is well aware how large the seed is. I couldn't find the original reference, but there's a few papers on how there are South American plants that now geographically isolated because there's no megafauna to eat and disperse the seeds.
- brnt 4y agoI'm assuming any fruit or veg grown by humans are heavily tuned versions of some wild ancestor, and may seem to have little in common with it. How 'original' are the avocados we all know and love?
