Question

List nine traits that developed during human evolution. Two species that have each trait (you can't use the same species twice so it must be two new species for each trait) and approximately in millions of years when these adaptations took place.

Answer 1

Evolution happens once these patrimonial variations become a lot of common or rare during a population, either non-randomly through activity or every which way through genetic drift one in all the earliest shaping human traits, bodily property -- the power to steer on 2 legs -- evolved over four million years past, different necessary human characteristics -- like an oversized and complicated brain, the power to form and use tools, and therefore the capability for language -- developed a lot of recently.

Humans take issue from all the opposite four hundred primate species in several respects, a number of the foremost placing ones being that they walk absolutely upright on their hindlegs, have big brains, Associate in Nursingd have an effectively naked rather than fur‐covered skin.

The 9 human traits: bodily property, Encephalization (big brain), F = body covering fat, N = status, L = descended speech organ, S = speech, civilization, Survival of the Fittest, activity. There was no general agreement among the respondents on why any of the unambiguously human traits have evolved: None of the planned hypotheses was universally either accepted or rejected. For somebody attribute, the share of respondents UN agency found none of the hypotheses “very likely” was between >30% (bipedalism) and >65% (nakedness).

In general, opinions on the credibleness of the hypotheses were freelance of an individual's background (gender, age, field of experience, degree of scientific experience), however (paleo)anthropologists were clearly a lot of vital than representatives of different fields. Evolution involves the gradual changes from straightforward to a lot of advanced forms. Humans are believed to possess developed from less complicated forms.

The evolution is hypothesized to possess begun within the oceans billions of years past. The Origin of Species, Darwin has mentioned that evolution has occurred through a series of activity. Struggle for Existence, Variation, Survival of the Fittest, activity

Evolution is that the results of the interaction between the subsequent 5 processes: Mutation, Genetic Recombination, body Abnormalities, activity, procreative isolation activity could be a mechanism, or cause, of evolution.

The lack of agreement on why humans evolved the traits we have today is very obvious in our results: No hypothesis was universally accepted, and for most traits, there were several almost equally popular alternative hypotheses rather than one that would generally be considered superior to the others.
