Lamarck evolution theory

[Kujiro]

Doing a science genetic research for my paper,
Thud became a point of group discussion, hence opening it to the floor for discussion and contribution.

It's been proven in the recent years by epigenetics that lamarck's theory of inheritance was partly correct on a molecular level.

Elephants walk long distances to get water at certain parts of the world during pregnancy, when the cub is horn it's able to retrace it's steps the mother took, without going through on it's own.
Labeling as soft inheritance, although a firm believer of sexuaility by not being a choice, is it possible that it's soft inherited through ancestry ?

Assuming thus to be true, homosexuality being inherited would be a logical paradox.
Hence evolving into bisexuality.

As Lamarck theorized that giraffes grow longer necks over time to reach leaves on higher ground, and elephants grew longer noses to reach for food.

While Darwin theorized that the weaker race died out and adapted to natural survival.

Anyone has any thoughts on this too add and share?

Disclaimer: I know nothing about the topic except what was in the OP. My analysis is strictly from a logical standpoint.

From what I'm understanding, this 'soft inheritance' deals with memory, not mental processes. The baby elephant remembers the trip, and can therefore make the trip on its own. The trip did not alter it's mind in any way.

I believe your conclusion is flawed for the reason stated above.

As Lamarck theorized that giraffes grow longer necks over time to reach leaves on higher ground, and elephants grew longer noses to reach for food.
Are the necks and trunks growing longer, or are they just stretching out over years of constant, well, stretching. Much like people gauge their ears and some African tribesmen use neck plates to elongate their necks.

While Darwin theorized that the weaker race died out and adapted to natural survival.
I'm pretty sure this is fact. I can't think of a single example of a surviving 'less evolved' species.

But the baby elephant was not born yet, how did it know the exact path to take?
It can't be memory.

That's where I get confused, about the paradox.

But it's true that darwin's theories were more accepted until recently, where its said that larmarck could be partly correct.

That's cool. It's true that genetic traits can affect personality. For example, in our hunter and gather era men who produced a certain type of hormone that made their mindsets happier were more likely to make children with women. These happier men were more likely to be nicer to children and be a more caring mate rather than abandoning their children and mistreating their female mates.

Of course now we do have guys who are mean to kids and beat their wives, but a large majority of men are kind( a term that is open to interpretation) fathers and try their best to please their wives.

How many times do you hear, "You got your mother's temper." or " That's grandma's kindness right there."? You can't pass down personality traits per say but you can pass down small things that will affect your child's personality.

The theory that bisexuality is passed down is very plausible to me.

It doesn't know the path to take (unless there;s something else you're not saying). This Lamarck evolution sounds to me like Pavlovian classical conditioning. It's not that the baby elephant knew where to go, but that it knew the path to take from a starting position.

To be more clear, it's not saying to itself "well, time to go to the watering hole, good thing I know how to get there." It's simply walking along a path that it's physical self has traveled many times before.

This is possible because a fetus is capable of taking in sensory information before they're born.

It can't be memory.
Why not? Rejecting a conclusion out of hand isn't good science. Conditioning (memory) could very well explain the evidence.

So it's possible that it's not inherited, but rather the fetus is able to take sensory information before their born.

I see would read up more on that part.
:) thanks for the tip
