One of my friends in maybe first grade asked me that why do giraffes have long necks? and when i said, i don't know, he bragged that giraffes once did not have long legs or neck, but it started to stretch towards trees and little by little, it morphed into a tall giraffe by generations.

As if their change in body parts during their lifetime was being inherited.

And these changes, these acquired long necks were passed into the next generation.

And even as a six -year -old, it didn't make sense to me.

Like, if giraffs morphed that way, then why didn't other herbie wars, like maybe cows or something? and once i took evolution in seventh grade and above, i realized that, this theory is wrong.

Physical changes especially is not inherited most of the time during its lifetime.

In women, meiosis happens very in the beginning and only those haploid genes are being passed.

But when we look at the other two theories that do all species have a common ancestor, then that makes sense.

We see those in our phylogenies...
