Human Evolution

Human evolution is the process of evolution of humans from early man to anatomically modern humans. The process of evolution in humans leads to the gradual development of traits like bipedalism. Humans are the highly social animals that make them the most advanced animal on Earth. Human evolution is an outcome of interaction among the following processes:

Question

refers to evolutionary changes that occur when two similar species inhabit the same environment, natural selection favours a divergence in phenotypic traits.

		natural selection
		phenotypic plasticity
		character displacement
		none of the options are correct
		sexual selection

The percentage of women with "morning sickness" is highest during the _____________ trimester, when sensitive fetal tissues are developing rapidly.

third

last

first

none of the options are correct

Definition Definition Observable physical traits or characteristics of an organism, which are determined by its genetic makeup (genotype) as well as environmental factors. These traits can include anything from eye color or height to behavior or disease susceptibility. Understanding an organism's phenotype is important in fields such as genetics, medicine, and ecology.

Some worms eat at night (meaning they are nocturnal) and some worms eat during the day (meaning they are diurnal.) Most birds eat only during the day, so they are only eating diurnal worms, due to the fact that the nocturnal worms are burrowing during this time. Each spring when the worms reproduce about 500 offspring are born but only 100 of them live long enough to reproduce themselves. Explain how natural selection will occur and include the 4 principals of natural selection.
Climate change is an increasing threat that scientists are trying to not only combat but prepare for future increases in temperature and rainfall. One of the effects of climate change is the warming of ocean and air temperatures. The sex of sea turtle offspring is determined by temperature during development. Temperature over 87° Fahrenheit will result in female offspring. In 3-5 sentences, describe how organisms like the sea turtle might adapt to the rise in ocean and air temperatures. In your explanation, describe the correlation between environmental factors and natural selection.

The images below depict a female and male primate of the same species. Based on these images, would you agree that a high degree of sexual dimorphism is present? If so, what traits indicate this? Mark all that apply. Group of answer choices No sexual dimorphism - these would be considered an example of sexual monomorphism. Male is much larger in overall size Male has a sagittal crest Male has much larger canines.
Natural selection acts upon ____________________________, evolution upon _______________________________. What is the gene pool and how does natural selection act upon it? If a version of a gene confers an advantage to survival and reproduction, that version of the gene will be favored by natural selection and we can expect the frequency of that gene to ______________________ within the population over time. Versions of the gene that do not confer an advantage (or confer a disadvantage) should become _______________ prevalent . This generation to generation change in the gene pool is called ________________________. Changes to the genetic makeup of a population and the individuals within it can arise via two mechanisms. List and describe both. Both of these processes are ________________________________. Once created, new combinations of genes will be acted upon by _________new alleles_______________________. How is Darwinian “fitness” different than the typical definition used in…

In sexual reproduction, gametes that are large have the advantage of providing a good amount of resources for the developing offspring. Gametes that are small have the advantage of mobility. We call large gametes eggs and small gametes sperm. Medium-sized gametes neither have enough resources for the developing offspring nor they have the capacity of mobility and hence, are eliminated by natural selection. Which type of natural selection is this an example of? -stabilizing selection -sexual selection -directional selection -disruptive selection
The sex of sea turtle offspring is determined by temperature during development. Temperature over 87° Fahrenheit will result in female offspring. What is the correlation between environmental factors and natural selection in how the sea turtle might adapt to the rise in ocean and air temperatures.
The images below depict a female (left) and male (right) primate of the same species. Based on these images, would you agree that a high degree of sexual dimorphism is present? If so, what traits indicate this? Mark all that apply. Group of answer choices Yes, a high degree of sexual dimorphism. No sexual dimorphism - these would be considered an example of sexual monomorphism. Male has much larger canines. Male has a sagittal crest Male is much larger in overall size
Which of the following statements is NOT an observation or inference on which natural selection is based? Group of answer choices Only a fraction of an individual’s offspring may survive. Species produce more offspring than the environment can support. There is heritable variation among individuals. Modifications of an organism acquires during its lifetime can be passed to its offspring.
Environments all over the world are changing as a result of global warming. Will this cause natural selection to occur? A. No.The environment is always changing. Global warming is nothing new. B. Yes, warmer temperatures will induce mutations that are favorable to survial in the new teperature regime C. No. The only change will be that species from hot environments will expand their ranges. D. Yes. Traits that help individuals produce more offspring in warmer environments will increase in frequency. E. Yes. Warmer temperatures will increase the rate of chemical reactions in poikilothemic species and thus natural selection will be enhanced.
In your own words, explain the factors that lead to the Phenotypic variation and its importance to evolution.
