Death and Evolution

[FearGod]

I don't like to encourage the spread of gross misinformation.

But you said you aren't a biologist and you don't know the answer, dishonesty always and always and always.

 

[FunctionalAtheist]

Is becoming old and die was good for the species?
Death is good for earth and for more species to come which is a sign that someone
has planned for it, living for some years and giving birth for new comers.

What do you think? was it just a coincidence or a programmed death mechanism?

With all respect, yes, death is good for the species! But it is in no way a sign of design or planning. You limit the responses.

 

[FunctionalAtheist]

Why incremental changes won't happen if there's no death?
I didn't say there's no reproduction.

Incremental changes will happen....this causes death...see "competition"

How it's good for the species in terms of survival and fitness?

 

[metis]

To make room for others since overcrowding/overpopulation is a threat to any organism.

Evolution requires 4 things. One of these things is competition for limited resources. Individuals that can't compete as well as others die, thereby freeing up limited resources for more fit individuals. If none ever died, then all would starve.

The slowest reproducing animals on earth, elephants, would completely cover earth in 100 years if none died.

And who planned for making room for the others?

And how aging and becoming old and weak is naturally selected?

 

[FunctionalAtheist]

And how aging and becoming old and weak is naturally selected?

Because no organism is perfect...we have genes that are favorable early in life, and genes that are favorable later in life. One hypothesis is that genes favored early, when most active reproduction occurs, are favored over genes for longevity. There are other hypotheses as well. Here is a very brief summary. The Evolutionary Theory of Aging and Life History Theory

 

[FunctionalAtheist]

And who planned for making room for the others?

There is no plan, it is just a fact of life that ALL species have the capacity to reproduce at a rate that will outstrip available resources. In some species more than 99% of all offspring die before reaching maturity. They die because they are slower, or because they are not as good at competing for the limited resources, or for many other reasons.

Why humans live to around 100 and not 40? how that was naturally selected?

Many die before 40. Nearly all die before 100. There are as many evolutionary strategies as there are species. It's interesting to note, from the link I posted above, that the life span of flies was increased by postponing the age of first breeding.

IFF humans were not allowed to reproduce until age 30, then the average age of humans would increase through selection out of 'younger' genes and selecting for slightly 'older' genes. If after 10 or so generations humans were not allowed to reproduce until age 40, life span would increase again. Through this process, with humans, pigs, or flies, life span can be increased. THIS IS NOT HYPOTHETICAL, it has been done in the laboratory with several species.

In this way, it is similar to a law of averages. While we do not, as humans, limit the reproductive age of others, nature has, for each species, a range in which reproduction is at it's highest. Past this age aging begins taking it's toll.

And how aging was due to mutations and natural selection?

You're assuming that it had to be planned. What we now know is that the laws of physics do not have to be planned, especially since these laws are not uniform, as quantum mechanics has shown us.

Everything seems to deteriorate over time, but while that's going on new combinations are borne everyday. We are born; we live; we die; but then others are born; they live; etc.

So answer my question according to science.

Why our lifespan is uniform, why not some aged at 30 and some at 40 and some others
at 150, why not 200 ...etc?

Because we don't have the same genetic make-up, nor do we all experience the same events in our lives.

So, since you believe in an Abrahamic concept of God, why did God make people different? Why do some die young? Why are there miscarriages? Seems sort of strange if God is a caring God, doncha think?

My question is why we aged the same? why aging is uniform?
IOW you won't see some people got old at 30, or you see young people at 70,
why aging is uniform?

 

[metis]

But we're not.

 

[FearGod]

But we're not.

Do you see some people aging at 30? and some others are still young at 70?

 

[Jose Fly]

Why humans live to around 100 and not 40? how that was naturally selected?

You had that question answered before. Remember r/K selection?

Or are you yet another creationist who demands we answer your questions and explain things for you, but then you ignore/forget it all?
